Title: Innovations by Wen-Shyang Tsai

Introduction

Wen-Shyang Tsai is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to device structures and etching processes.

Latest Patents

One of his latest patents is titled "Mechanisms for forming protection layer on back side of wafer." This invention provides embodiments of mechanisms for forming a semiconductor device structure. The structure includes a substrate with a front side and a back side, devices formed on the front side, and interconnect structures on the devices. Additionally, it features a protection layer on the back side of the substrate, which has a thickness of over about 10 A.

Another significant patent is the "Thermocoupled lift pin system for etching chamber." This system comprises multiple thermocoupled lift pins that can be vertically extended from a heater block inside a semiconductor etch chamber. The lift pins lower a semiconductor wafer onto the heater block before the etching process and lift it afterward. If the wafer's temperature exceeds a predetermined value post-etching, the lift pins trigger the release of a cooling purge gas, such as nitrogen, into the chamber. This initial cooling prevents thermal stressing when transferring the wafer to a cool down chamber.
