Latest Patents

Shimizu's latest patents include a groundbreaking semiconductor device that describes a multi-step fabrication process. The procedure begins with the formation of a gate insulating film, followed by a gate electrode and an on-gate protective layer on a silicon substrate. Lightly-doped source and drain regions are established, and first and second sidewalls are formed around the gate electrode. Heavily-doped source and drain regions are generated by implanting dopant ions using these sidewalls as masks. A critical aspect of his invention lies in the selective removal of the second sidewall before depositing an overall protective film, allowing for an unfilled gap between adjacent gate electrodes. This design minimizes the risk of short circuits between the gate electrode and contact members while contributing positively to device miniaturization.
