"Roll to Roll Processing
for Microelectronics Manufacturing"
- James Sheats, Ph.D.

Many emerging device technologies, including organic light emitting diodes, organic transistors, various reflective displays based on electrophoretic materials or liquid crystals, solid state memories, and batteries, are considered of value in large part because of the promise of lower cost of manufacturing. However, if the manufacturing paradigm is that of wafer or sheet-based processing, the equipment cost and throughput does not change significantly, and may even be worse due to difficulties in handling flexible substrates. These technologies will realize their full potential only if manufactured in a continuous roll process.

Typically the preferred substrate for web processing is
plastic (although metal foils have been used). Plastics present significant challenges in mechanical stability during handling and thermal cycling. Nevertheless, good quality amorphous silicon solar cells are being produced on polyimide, and Rolltronics has now made the first thin film transistors using the same equipment. The talk will review the issues and potential for this exciting field.

Biography for speaker:

James Sheats received his Ph.D. in Physical Chemistry from Stanford University in 1978. After postdoctoral work in nonlinear dynamics at MIT and Stanford, he joined Hewlett- Packard Laboratories, where he worked on a wide variety of projects in thin film electronics, including photolitho- graphic chemistry, high temperature superconductivity, and organic electroluminescence. He is currently chief technical advisor for Rolltronics Corp. Dr. Sheats has authored more than 40 papers and 12 patents and co-edited two books, and is a fellow of the American Association for the Advancement of Science.
