Patterned by Printing—a New Approach to Printed Electronics
Carolyn R. Ellinger
Kodak Technology Center
"Printing by pattering" is an alternative approach to printed electronics where the patterning is achieved by printing, but the active material is deposited via atomic layer deposition (ALD). The three key elements of our "patterned by printing" approach are: 1) spatial ALD, 2) inhibitor materials and mechanisms, and 3) printing methods. Each of these elements will be discussed and linked into a process flow for fabricating ZnO thin film transistors (TFTs). Performance data from representative TFTs made using this method will be presented that show the potential to form high quality devices and ultimately circuits via roll compatible processes.
