Title: Lee Yu-Chou: Innovator in Liquid Crystal Technology
Introduction
Lee Yu-Chou is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of liquid crystal technology, holding 2 patents that address critical challenges in manufacturing processes.
Latest Patents
One of his latest patents is a manufacturing method and structure of copper lines for a liquid crystal panel. This invention addresses issues found in conventional arts, particularly for large-size LCDs. The traditional process of copper damascene interconnect often results in an uneven copper seed layer and hollows during electrical plating due to the large electroplating area. Lee's innovative approach employs a Cu tape that directly adheres to a substrate, eliminating the need for a copper seed layer and electroplating. This method effectively resolves the problems of unevenness and hollows, making it suitable for large-size LCD applications.
Another significant patent by Lee is a method for reducing contact impedance of thin film transistors (TFTs). This invention focuses on enhancing the contact impedance of a gate electrode in TFTs. It utilizes a double layer of AlNd/Cr or AlNd/Cr silicide as the gate electrode material and incorporates a plasma atmosphere to clean the contact surface. This advancement contributes to improved performance in thin film transistors.
