Latest Patents

One of Wei Yip Loh's latest patents is the "Fully Salicided (FUCA) MOSFET Structure." This patent describes a method to form a MOSFET with a fully silicided gate electrode and raised source/drain elements that are nearly coplanar. This design allows for a wider process margin when forming contacts to silicided regions. The process involves forming an insulator block layer over shallow trench isolation (STI) regions and using a conformal silicidation stop layer. The resulting structure enhances the performance of MOSFETs by utilizing a gate electrode and raised source/drain elements comprised of NiSi.

Another significant patent is the "Method of Fabricating Tensile Strained Layers and Compressive Strain Layers for a CMOS Device." This process enables the formation of both tensile and compressive strained silicon layers, accommodating channel regions of MOSFET or CMOS devices. The method involves the deposition of a semiconductor alloy layer followed by an oxidation procedure that segregates a germanium component into an underlying single crystalline silicon body. This innovation allows for different levels of strain in the subsequently deposited silicon-germanium layer.
