Student projects within Holst Program Lithography on flexible substrates

At TNO, Patterning for Flexible Systems

Lithography is well established in semiconductor industry, and is employed in manufacturing computer processes, image sensors for optical digital cameras, an DRAM / NAND flash memories; however, optical lithography on flexible substrate is relatively new technology, with different challenges ahead. Our goal is to pattern conductive circuits with nanometer and micrometer dimensions, on flexible substrates, making use of optical lithography, as well as developing novel processes and materials. As part of the student research project, the next areas of activity have been proposed:

• Imaging / Patterning with Maskless Optical Lithography
• Photo induced Reduction of Metal Complexes in Thin Polymer Films
• Direct patterning of metal nanoparticles by combined photo-imprint lithography

Your tasks will be:

Literature research to provide you with the required theoretical background about lithography and nanoparticles formation and properties

• Perform experiments in laboratory and clean room (substrate preparation, exposure, development)
• Fine-tune process parameters (concentrations, deposition methods, exposure conditions)
• Evaluate results and interpret data obtained with various characterization techniques (AFM, optical microscopy, SEM / TEM, UV-Vis absorption spectroscopy, electrical properties, ect.)
• Participate in group meetings, provide feedback, discuss results and propose solutions to various challenging aspects
• Write experimental reports, technical notes

This is a great opportunity for an internship in an exciting environment, doing cutting edge science and research, at the border between materials science, chemistry and engineering. You are an enthusiast student with a background in physical sciences (chemistry, physics, materials science, chemical engineering), with experience in laboratory activities, good academic records, at least some exposure to characterization equipment (microscopes) and good communication skills in English. If interested in joining our team and finding out more details about our research, send your resume and a cover letter to Dr. Marius Ivan (marius.ivan@tno.nl)
