Title: Hsiao Shih-Yi: Innovator in Semiconductor Technology
Introduction
Hsiao Shih-Yi is a notable inventor based in Taibau, Taiwan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approaches to manufacturing processes.
Latest Patents
One of his latest patents is titled "Method for wet etching of high k thin film at low temperature." This invention discloses an electrode structure of a light-emitting diode (LED) and the manufacturing method of the electrodes. The process involves forming a pn junction of an LED on a substrate, depositing a layer of SiO2 on the periphery of the die near the scribe line of the wafer, and then applying a transparent conductive layer. Following this, a layer of gold or AuGe is formed with an opening at the center of the die. The invention also details the formation of ohmic contact through heat treatment and the creation of both positive and negative electrodes on the front side of the LED.
Another significant patent by Hsiao is the "Puddle etching method of thin film by using spin-processor." This method involves pre-wetting the wafer with deionized water and etching solution to remove contamination. The wafer is then spun slowly while injecting the etching solution to create a puddle that remains on the wafer, allowing for effective etching. After the etching process, the wafer is rinsed and dried using a specific sequence of spinning and chemical treatments.
