Latest Patents

Ju-Yu Chang holds a patent for a "Self-aligned process for a stacked gate RF MOSFET device." This patent describes a novel process for fabricating RF type MOSFET devices, focusing on reducing performance-degrading gate resistance. The process features the formation of a stacked gate structure, which includes a metal gate contact structure directly overlying a portion of an underlying polysilicon gate structure. This design is strategically placed on an active device region of a semiconductor substrate. The subsequent formation of an overlying metal interconnect structure results in reduced gate resistance due to the direct vertical conductive path from the metal interconnect structure to the polysilicon gate structure, facilitated by the metal gate contact structure. Notably, this process sequence requires no photolithographic processing, allowing for self-alignment of the metal gate contact structure to the underlying polysilicon gate structure.
