Title: Shau-Tsung Yu: Innovator in Semiconductor Technology

Introduction

Shau-Tsung Yu is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of semiconductor technology, holding a total of 4 patents. His work focuses on improving the manufacturing processes of integrated circuits, particularly in read-only memory (ROM) and field-effect transistors (FETs).

Latest Patents

One of his latest patents is titled "Post metal code engineering for a ROM." This invention provides a method of manufacturing a read-only memory that is code implanted late in the process after the first level metal, thus reducing the turnaround time to ship a customer order. The invention comprises several steps, including forming bit lines and word lines in a cell area and MOS transistors in a peripheral area of an integrated circuit. It also involves programming the ROM region by implanting impurities into the substrate under selected word lines.

Another notable patent is the "Method for preventing fluorine outgassing-induced interlevel dielectric." This method describes a process for forming P-channel field effect transistors with shallow source/drain junctions and improved reliability for CMOS circuits. The invention provides an improved process that uses a photoresist block-out mask to eliminate the implantation of BF2 ions in the P-channel FET gate electrodes, preventing voids from forming at the gate electrode/interlevel dielectric interface.
