Publication number: 20140138692Abstract: Disclosed is a method of forming array substrates having a peripheral wiring area and a display area. The method is processed by only three lithography processes with two multi-tone photomasks and one general photomask. In the peripheral wiring area, the top conductive line directly contacts the bottom conductive line without any other conductive layer. The conventional lift-off process is eliminated, thereby preventing a material (not dissolved by a stripper) from suspending in the stripper or remaining on the array substrate surface.Type: ApplicationFiled: January 28, 2014Publication date: May 22, 2014Applicant: INNOLUX CORPORATIONInventor: Cheng-Hsu CHOU

Patent number: 8273590Abstract: Disclosed is a patterned photoresist layer on a passivation layer, formed by a lithography process with a multi-tone photomask, having a non-photoresist region, a thin photoresist pattern, and a thick photoresist pattern. The passivation layer corresponding to the non-photoresist region is removed, thereby forming vias to expose a part of a drain electrode in a TFT and a part of a top electrode in a storage capacitor, respectively. The thin photoresist pattern is then ashed to expose the passivation layer in a pixel region. Thereafter, a conductive layer is selectively deposited on the exposed passivation layer and on the sidewalls/bottoms of the vias. Subsequently, the remaining thick photoresist pattern is ashed.Type: GrantFiled: March 17, 2011Date of Patent: September 25, 2012Assignee: Chimei Innolux CorporationInventor: Cheng-Hsu Chou
