Publication number: 20090029527Abstract: A non-linear element is formed on a flexible substrate by securing the substrate to a rigid carrier, forming the non-linear element, and then separating the flexible substrate from the carrier. The process allows flexible substrates to be processed in a conventional fab intended to process rigid substrates. In a second method, a transistor is formed on a insulating substrate by forming gate electrodes, depositing a dielectric layer, a semiconductor layer and a conductive layer, patterning the conductive layer to form source, drain and pixel electrodes, covering the channel region of the resultant transistor with an etch-resistant material and etching using the etch-resistant material and the conductive layer as a mask, the etching extending substantially through the semiconductor layer between adjacent transistors.Type: ApplicationFiled: October 1, 2008Publication date: January 29, 2009Applicant: E INK CORPORATIONInventors: Karl R.
