Latest Patents

WenYan Liu holds a patent for a method of manufacturing the trench of U-shape. This invention relates to the manufacture of CMOS semiconductor devices. The process involves several steps: first, a layer of silicon oxide is deposited to cover the surface of the polysilicon gates and the exposed upper surface of the silicon substrate. The silicon oxide layer is then removed from the upper surface of the exposed silicon substrate, followed by the formation of a barrier layer at the surface of the polysilicon gates. Next, ions are implanted into the exposed substrate, resulting in the formation of several doped silicon regions. These regions are subsequently etched to create the U-shaped trench, after which the barrier layer is removed. This innovative method protects the polysilicon gate and the substrate during the trench formation process, increases the etching rate, improves productivity, and allows for better control over the depth of the U-shaped trench. WenYan Liu has 1 patent to his name.
