Introduction

Yen-Shou Kao is a prominent inventor based in Taichung, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work focuses on innovative methods for fabricating semiconductor devices, which are crucial for modern electronics.

Latest Patents

One of his latest patents is titled "Method of forming self-alignment contact." This patent discloses a method for fabricating a semiconductor device that includes forming a first gate stack over a substrate. The first gate stack consists of a gate electrode, a first hard mask disposed over the gate electrode, and sidewall spacers along the sidewalls of the first gate stack. The method also involves forming a first dielectric layer over the first gate stack, followed by the formation of a second hard mask over the first hard mask and the top surfaces of the sidewall spacers. Additionally, a second dielectric layer is formed over the second hard mask and the first dielectric layer, and the removal of these layers creates a trench that exposes a portion of the substrate while the second hard mask remains over the first gate stack.

Another notable patent is "Semiconductor device structure and method for forming the same." This method includes forming a gate stack, a spacer layer, and a dielectric layer over a substrate. The process involves removing a first portion of the dielectric layer to create a first hole, with a second portion of the dielectric layer located beneath it. A first protection layer is formed over the gate stack and spacer layer, followed by a second protection layer that includes a metal compound material. The method concludes with the removal of the second portion of the dielectric layer to form a through hole, allowing for the formation of a conductive contact structure within it.
