Latest Patents

Polysilicon Layer Having Improved Roughness After POCl3 Doping. This invention describes a two-stage polysilicon deposition process for forming a gate pedestal. Deposition begins at approximately 630°C and continues after the temperature is lowered to about 560°C, without interrupting film growth. The resulting surface is smoother because the top layer is less prone to uncontrolled grain growth. Oxidized dielectric layers made from these films can consequently achieve improved breakdown voltages.

Conical Baffle for Semiconductor Furnaces. This invention describes a conical baffle positioned inside a furnace tube between the gas inlet and the wafers. The apparatus is designed to improve the uniformity of thin-film growth and dopant distribution across semiconductor wafers and other substrates.
