Title: Yih Song Chiu: Innovator in Semiconductor Technology

Introduction

Yih Song Chiu is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.

Latest Patents

Chiu's latest patents include a method for feature dimension measurement. This method involves providing a substrate and forming a reflective layer over it. A dielectric layer is then created, which includes a grating pattern and a resistivity test line inset in a transparent region. Radiation is directed onto the dielectric layer, allowing some of it to transmit through the transparent region to the reflective layer. The resulting radiation pattern is analyzed to determine first dimensional information. Additionally, the resistance of the resistivity test line is measured to ascertain second dimensional information, which is then compared to the first.

Another significant patent by Chiu is a method of forming a shallow trench isolation (STI) feature to avoid electrical charge leakage. This method includes providing a substrate with an overlying hardmask layer, patterning the hardmask layer to create an opening for etching a trench, and carrying out a wet chemical oxidizing process. The process results in a completed planarized STI structure filled with oxide, enhancing the performance and reliability of semiconductor devices.
