Latest Patents
Masafumi Shinbo holds a patent for a method of producing a liquid-crystal display device. This patent describes a process where a thin film transistor array for an LCD is produced by simultaneously forming gate electrodes and picture element electrodes. The method involves creating islands of a layered structure, which includes a gate insulating film, a thin semiconductor film, and a light shielding film, all in a single masking step. Additionally, the gate, source, and drain wiring metals are formed in contact windows using the 'lift-off' technique after employing a resist film for opening the contact windows. This innovative approach requires only three masking steps, significantly increasing production yield and lowering production costs compared to conventional techniques that typically require seven masking steps.
