Latest Patents

Among his latest patents is a comprehensive method of fabricating semiconductor devices. This method involves a series of strategic steps: first, forming a well of first conductivity type in combination with a well of second conductivity type within a substrate. Subsequently, it includes the formation of both a field oxide layer and a gate oxide layer on the substrate. The process is further enhanced by forming first and second polysilicon layers on the aforementioned layers, where the first polysilicon layer is doped with impurities of the second conductivity type and vice versa.

The innovation lies in the patterning of these polysilicon layers, which isolate them from each other to form distinct gates. Additionally, a conductive layer is strategically placed between the gates to connect them electrically. This approach not only simplifies the etching process during gate patterning by utilizing a single mask but also effectively prevents the mutual diffusion of doping impurities across the polysilicon layers.
