He spoke of the challenges of printing transistors to be used in flexible displays. These transistors require very precise printing of a line source and drain with 1 um spacing. Print speed is 1 MPM. Subsequent layers for the gate and dielectrics do not require the same precision. His research has selected gravure print technology and work involves modeling the print process well enough to make tools to deliver the desired shapes. The need is to get the tools into the hands of electronic circuit designers so they can work on the product rather than the process.
Gravure printing at these geometries needs compensations in filling wells, wiping the wells, transferring to the substrate and drying.
Magnetic plates are made on silicon wafers using traditional lithography.
A very good introduction to the conference.
