Latest Patents

One of his latest patents is a method for forming a polysilicon germanium layer. This innovative technique allows for the formation of a polysilicon germanium layer on a gate oxide layer without the need for a polysilicon seed layer. The process utilizes chemical vapor deposition at temperatures ranging from about 500°C to about 600°C, employing SiH (disilane) gas and a germanium-containing gas as precursors. This results in a polysilicon germanium layer with a smooth surface directly formed on the gate dielectric layer.

Another notable patent addresses the reduction of surface humps in doped amorphous silicon layers. This method involves forming a dielectric layer on the device, followed by patterning to create openings for electrode exposure. A series of deposition steps are performed to create a conformal first doped amorphous silicon layer, followed by an undoped or lightly doped layer, and finally a second doped layer. This innovative approach effectively mitigates surface hump phenomena.
