Title: Understanding the interplay of surface, interface and process parameters on thin film magnetic materials used in advanced sensors

Funding sources: Science Foundation Ireland (SFI)/ Analog Devices International

Amount of Project Funding: €646,500

Type: Industrial R&D in ADI premises

Purpose: The purpose of the SFI Industry Fellowship Programme is to enhance industry-academia collaborations. The main research and development objective of the fellowship is to build new generation fully integrated with CMOS architecture sensors and devices based on existing Analog Devices (ADI) technology.

Reference: UL/ADI

Personal involvement and contribution: ADI has a wide range of innovative products include data converters, amplifiers and linear products, radio frequency (RF) ICs, power management products, sensors based on micro electro mechanical systems (MEMS) technology and other sensors. Some of the current areas of interest for Analog Devices are iCoupler® technology, magnetic field sensors, and energy harvesting technologies. ADI supply products, such as high precision AMR angle sensor ADA4571 and isoPower® products ADuM524x. The next generation of these systems poses several materials, technology, and integration challenges. During the tenure of the project, I have been involved in seven key development projects as a senior scientist. My role was to design the experiments (for advanced material and device processing), literature review and preparing final reports. I was fundamentally involved in the development of magnetic core  micro-transformer project. The magnetic core transformer is a new generation of the products in the iCoupler® technology. I was also involved in R&D for the thermoelectric generator and pre-silicide cleaning for 0.18 µm dual gate CMOS. Apart from that I have provided the failure analysis on root causes of magnetic core losses, failure of lithographic and sputtering process in micro-transformer, isolator, AMR sensor and thermoelectric projects at various stages of the process using FIB, SEM, EDX, XPS, TOF-SIMS, TEM and electrical characterization. In total over 60 reports were prepared for the company which boosted the development. The key achievements are

  • Solving wafer bow problem in magnetic core transformers that were causing handling errors in auto-processing tools and lithographic errors. It was one of the major milestones of the project. The job was initially expedited to three external vendors including two companies and one research institute who were not able to develop the solution compatible with ADI processing.
  • Development of first selective wet etch solution for magnetic multilayer on Si. That improved products quality factor from 6 to 12 and reduced three processing steps which will minimize the overall cost of the unit by 20%. This job was expedited to external vendor initially where it failed.
  • Failure analysis on developments projects at various processing steps to understanding root cause of failures
  • Developed lift-off process for high temperature and higher thickness layers

As an SFI industry fellow, I actively worked to develop long term partnership between ADI and UL. ADI top hierarchy is seeing the fellowship a huge success; now we have one Employment based Postgraduate Scholarship and one Master’s student with ADI (working in the research areas that I have started).  The chances of ADI’s involvement in the future partnerships with UL are bright.

Title: Low tolerance and Cost effecting formulations for Positive Temperature Coefficient thermistors (LoCo-PTC)

Funding sources: Enterprise Ireland Innovation Partnership

Amount of Project Funding: € 368,734

Type: Research, Industrial R&D

Purpose: The aim of this partnership was to develop novel ceramic powder formulations that will offer closer tolerance in electrical resistance for PTC thermistors.

Reference: UL/ BorgWarner Beru Systems Ireland Ltd

Personal involvement and contribution: As a senior postdoctoral researcher, my role was to lead UL team comprising postdoctoral researchers, technical staff, and students to achieve research and development goals on tight schedule and develop a working partnership with industrial partner BorgWarner to realize highly innovative industrial technology goals. I was involved in the development of the chemical formulation for powder processing, sintering process, microstructural, chemical and electrical characterization. MOSAIC team successfully reverse engineered commercial formulation used in PTC stones including La with a control over chemistry below

<0.05 atomic% using state of the art analysis tools at MSSI. We demonstrated highly reproducible PTC in La doped BaTiO3; suitable composition and process identified and disclosed to the company and identified process parameters to reduce drift in resistivity. We developed powder processing protocols and sintering profile for control over chemistry, densification, Tc and cold resistivity. We identified that a tight control over chemistry (e.g. La below 0.05 at%), Ba/Ti ratio and control over sintering profile is critical.

Title: Screen Printing of PTC Thermistors (SCREENSTOR) Funding sources: Enterprise Ireland Innovation Partnership Amount of Project Funding: €186,000

Type: Research, Industrial R&D

Purpose: The aim of this partnership was to realize a lead-based screen printable PTC thick film that the industrial partner, BorgWarner (BW) intends to translate into a low volume manufacturing product using its own in house screen-printing facility.

Reference: UL/ BorgWarner Beru Systems Ireland Ltd

Personal involvement and contribution: In this project, my role was to lead the team of UL researchers to develop screen printable PTC thick films from the powder chemistries developed in LoCoPTC. We developed a disruptive solution to the problem of manufacturability of PTC devices. This solution offers a significantly better manufacturability of PTC devices when compared to current PTC stone devices. The incorporation of the screen printable technology in PTCR is a highly desirable goal for the industry for many decades. The advantages of a multilayer (ML) or thick film PTCR would be the reduction of the total resistance, miniaturization, high throughput and low-cost production.  However, there were several challenges that hindered screen printable PTC for

e.g damage of electrical contacts in co-firing conditions, the porosity of the films and sintering profile for removal of unwanted chemicals.We have developed a process for the cast tapes that

 

 

 

 

provide sufficient green strength that can allow defect-free removal of the green tape from the substrate and handling for further processing steps such as transport and loading to calcination/sintering furnace or kiln and free standing calcination and/or sintering. The tapes do not require co-firing of electrodes thus major obstacle for realizing screen printable PTC has been overcome. We developed a formulation of PTC paste with optimized combination of particle size, solvent, binder, plasticizer and dispersant for high particle loading (over 70% content of functional powder) while sufficient flow property and viscosity for fully dense green tapes obtained by tape casting and of sufficient thickness (300-400 μm) in the tape in a single step with PTC effect.

Title: Real time optimization of dynamic spin-coating and blade-coating process for solar cell and semiconductor fabrication

Funding sources: University of Sheffield Amount of Project Funding: about £80,000 Type: Research

Purpose: Develop optical platforms to study real time optimization of phase separation in polymer blends.

Reference: UoS

Personal involvement and contribution: My work on the “Real time optimization of dynamic spin- coating and blade-coating process for solar cell and semiconductor fabrication” was particularly aimed to develop understanding of the process that would lead to better organic photovoltaics, light- emitting diodes, and solar cells. The performance of the organic semiconductor devices relies upon the nanoscale phase separation morphology of the blade or spin coated film. Understanding the factors that determine the final phase-separated morphology in these systems is consequently an important goal. In this study, I have used a direct laser imaging and exploited improved optics, light source and video capture methods to demonstrate a straightforward method to allow micrometer- scale lateral resolution and nanometer vertical precision metrology during the blade and spin-coated phase separation of a polymer blend from solution. It was demonstrated that real-time laser interference microscopy could be used to directly observe the dynamics of film formation and phase separation processes for a bar-spread polystyrene/poly(methyl methacrylate) blend. The ability to dynamically image laser interference patterns allows competing drying curves and polymer content to be determined throughout the film formation process. Our work on this topic is highlighted as a cover article in the journal of polymer physics 52, 985 2014; [Further details of my work on the spin coating in Journal of Polymer Science Part B: Polymer Physics 51, 875 2013].

Title: The exclusion force microscope

Funding sources: Infinitesma

Amount of Project Funding: £70,000 approximate Type: Research/Industrial R&D

Purpose: Development of “The Exclusion Force Microscopy” using dual frequency AFM imaging Personal involvement and contribution: I worked with Professor Jamie Hobbs on The Exclusion Force Microscope”. In this project, the possibility of AFM to beat the resolution limit imposed by tip shape and the water meniscus, and reveal the atomic structure of matter in ambient conditions was

 

 

 

 

explored. This relied on the fact that the frequency response of the tip sample interaction mediated through the water meniscus is different from that resulting from direct tip sample contact. This could be achieved by oscillating the cantilevers at two frequencies separated by at least a decade, and potentially in two different axes (e.g. laterally and vertically). The frequency and energy loss response of the cantilever was monitored as the interaction force is varied. In the time scale of the project, we observed features at high resolution when a sample was imaged in bimodal mode and data characterization procedures were set up using the software tool IGOR pro.

Title: Apertureless Photocatalytic nanolithography

Funding sources: Engineering and Physical Sciences Research Council (EPSRC)

Amount of Project Funding: £700,000 approximate Type: Research

Purpose: To develop photo-catalytic nanolithography (PCN), a simple generic method for patterning organic films based on the photocatalytic degradation of adsorbates.

Personal involvement and contribution: I developed aperture-less PCN by using a helium-cadmium laser (325 nm), to excite titanium-coated, contact-mode atomic force microscope (AFM) probes. The development of a photocatalytic lithographic process means that the approach is applicable to any substrate coated with an organic film and adoptable to commercial AFM. The control of protein organization on sub-100 nm length scales is known to present particular challenges. Proteins are able to adsorb strongly to most surfaces, because they display a wide variety of functional groups (charged and uncharged, cationic and anionic, hydrophilic and hydrophobic) and because they exhibit substantial conformational freedom. The control of protein conformation following binding to a surface remains challenging: not only is it difficult to control the orientation of the biomolecule but additionally, ensuring the retention of protein activity following immobilization on nanostructured surfaces is difficult because of the propensity for immobilized proteins to undergo conformational changes. Here, we used PCN to nanopattern (on sub-100 nm length-scales) self-assembled monolayers of alkyl thiols on gold and protein resistant OEG-functionalised silane monolayers on Si and glass. OEG functionalized silane were transformed to aldehyde functionalized regions by PCN that were derivatized with aminobutylnitrilotriacetic acid, and complexed with Ni2+, enabling the binding of histidine-labeled green fluorescent protein, which yielded bright fluorescence from 70- nm-wide lines that could be imaged clearly in a confocal microscope. [Further details of this work can be found in ACS Nano. 7, 7610 (2013)].

Title: SNOMipede

Funding sources: Engineering and Physical Sciences Research Council (EPSRC)

Amount of Project Funding: £3.2M Type: Research

Purpose: Development of novel instrument the “Snomipede”, to provide massively parallel for near- field optical nanolithography platform. beyond the diffraction limit.

Reference: http://www.leggett.group.shef.ac.uk/Snomipedemoreinfo.htm

Personal involvement and contribution: As the postdoctoral researcher, I led the highly ambitious instrument design that involved an open architecture AFM system constructed on an optical bench allowing the integration of additional optics for UV lithography, as well as multi-probe detection. [E. Haq et al. “Parallel Scanning Near-Field Photolithography: The Snomipede”, Nano Lett. 10, 4375 (2010)]. The open architecture enables the insertion of several different methods for coupling light to multiple probes. The focus of work has been particularly interesting as it enables the selective transformation of chemical structures on length scales as small as single biological molecules over macroscopically extended areas and in very rapid timescales. A team of investigators from four major  universities of UK (Sheffield,  Nottingham, Glasgow,  and  Manchester)  was assembled to

 

 

 

 

provide expertise across the breadth of science (from molecular biology through cell biology and organic synthetic chemistry to molecular electronics). Two different innovative approaches have been taken (the ability to continuously innovate was a feature of the team), none of which have been previously used in SNOM: the use of a spatial light modulator to (dynamically) create an array of diffraction limited laser spots in the focal plane of an objective and hence couple light to a probe array and the use of a custom fabricated zone-plate array to provide a small form factor method of individually focussing a series of light beams onto the cantilevers. As a postdoctoral researcher, I brought the idea of using state of art SLM technology which proved key for highly scalable multiprobe SNOM. My conference paper, Parallel Scanning Near-field Photolithography: The Snomipede was chosen as one of the outstanding papers from the 2010 MRS Fall Meeting. I was invited to write a feature paper in Journal of Materials Research [E. Haq et al. JMR 26, 2997 (2011)]. The development of a complex instrument such as this inevitably lead to protectable intellectual property and we filed a patent application (Lithography Apparatus and Method; GB1002099.8).

Title: Scanning Hot Electron Magnetic Microscopy (SHEMM)

Funding sources: Dutch foundation for Fundamental Research on Matter (FOM)

Type: Research/PhD

Purpose: Correlate nanoscale spin dependent transport, magnetic and microstructural properties of magnetic multilayers on Si

Personal involvement and contribution: My Ph.D. research was mainly focussed on understanding the physics of spin-dependent transport in ferromagnetic-semiconductor hybrid structures which form the basis of spin valve transistor, magnetic tunnel transistor, and magnetic tunnel junctions. I developed a technique (ballistic electron magnetic microscope BEMM from a modified STM); the technique uses STM tip as an emitter to inject hot electrons into the magnetic structure; thus is inherently capable of correlating surface nanostructure, magnetic imaging and spin-dependent transport in ferromagnetic semiconductor hybrid structures. I demonstrated a nano-scale magnetic hysteresis and high-resolution magnetic domain imaging (resolution »20 nm) [App. Phys. Lett. 86, 082502 (2005); 88, 242501 (2006)]. Conventional electronics components work with both electron and holes which enable the design of low power circuits. For emerging field of spintronics, it is highly desirable that spin dependent phenomena work both with electron and holes. However, the spin filtering of non-equilibrium holes remained unexplored. I demonstrated for the first time that large spin filtering also exists for non-equilibrium holes ferromagnetic semiconductor hybrid structures; details are covered in [“Spin- filtering of hot holes in a metallic ferromagnet”, Phys. Rev. Lett, 94, 027204 (2005)]. The Dutch Foundation for Fundamental Research on Matter (FOM) chose this work as one of the outstanding examples of research in the area.

Title: Impuls-1: Growth of fully relaxed SiGe layers on Si

Funding sources: Linkoping University Sweden

Amount of Project Funding: Type: Research

Purpose: Growth of relaxed SiGe layers for optoelectronic applications

Personal involvement and contribution:   I worked on growth and characterization of relaxed Si1-

 

 

 

 

xGex layers on Si substrate for optoelectronics and fiber optic applications. Thin films were grown using Molecular Beam Epitaxy (MBE). It was observed that the combination of a low temperature (LT) Si layer and an oxygen doped compliant layer grown at LT (200-250°C) assist the growth of thin, flat and highly relaxed Si1-xGex layers. Two dimensional X-ray Diffraction Mapping technique was used to determine the degree of relaxation and the composition of the Si1-xGex layers. Atomic Force Microscopy (AFM) is used to study the roughness of the relaxed layers. Further details in
