Introduction

Yi-Ching Wu is a prominent inventor based in Kao-Hsiung Hsien, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 13 patents. His work focuses on methods that enhance the manufacturing processes of semiconductor devices.

Latest Patents

Among his latest patents is a method for planarizing semiconductor devices. This innovative method involves several steps, including the provision of a substrate with a first dielectric layer covering at least one electrode structure. A chemical-mechanical polishing (CMP) process is performed on the first dielectric layer until the electrode structure is exposed. Following this, a second dielectric layer is deposited, covering both the electrode structure and the first dielectric layer. An etching-back process is then executed on the second dielectric layer until the electrode structure is again exposed.

Another notable patent is related to a semiconductor structure having a metal gate and its manufacturing method. This method begins with a substrate that has at least one first transistor formed on it. The first transistor includes a first conductivity type and a first metal gate, which is protected by a layer covering its sidewalls. The process involves removing a portion of the first metal gate to create a recess, followed by the removal of part of the protecting layer to form a second recess. An etch stop layer is then formed in the second recess, showcasing the complexity and innovation in his work.
