Latest Patents

Chang-Jen Wu holds a patent for a method of manufacturing a CMOS image sensor that is leakage-free with a double layer. This patent describes a method for forming a spacer structure for CMOS image sensors. The process involves forming a polysilicon gate electrode on a substrate, followed by the deposition of a thin layer of first dielectric over the exposed surfaces. A second layer of dielectric is then deposited, and etching is performed to create the electrode spacer. This innovative method ensures that the second layer of dielectric serves as an etch stop, preventing damage to the substrate surface between the gate electrode spacers. This technique also addresses the source/drain damage caused by the white pixel problem.
