Latest Patents

One of his latest patents is a method for forming offset spacers for semiconductor device arrangements. This innovative method enhances transistor short channel control by fabricating abrupt and tunable offset spacers. The process involves the formation of a gate electrode within a dielectric layer, with only a top portion of the gate electrode exposed. Silicon is added to the exposed portion through selective epitaxial growth. The etching of the dielectric layer utilizes the added silicon as a mask, preventing etching directly underneath and creating offset spacers in a production-worthy manner. This methodology allows for the creation of asymmetrical offset spacers, improving Vt roll-off by enabling wider spacers on narrower polysilicon gate features.

Another significant patent by Groschopf addresses the reduction of polish-induced damage in a contact structure by forming a capping layer. This capping layer is applied after a chemical mechanical polishing (CMP) process, effectively sealing surface irregularities. This innovation significantly reduces the risk of conductive surface irregularities during further processing, thereby minimizing yield loss effects caused by leakage paths or short circuits in the first metallization layer.
