Title: Kuo-Hua Yang: Innovator in Semiconductor Technology
Introduction
Kuo-Hua Yang is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of semiconductor technology, particularly through his innovative methods in photoresist stripping.
Latest Patents
Kuo-Hua Yang holds a patent for a method of photoresist strip. This method involves providing a semiconductor substrate and performing an immerse step and a strip step. The semiconductor substrate comprises a base, a bonding pad, a protective layer, an under bump metallurgy layer, a patterned photoresist layer, and a bump. The patterned photoresist layer covers the under bump metallurgy layer and a lateral surface of the bump. A first connection interface is formed between the patterned photoresist layer and the lateral surface of the bump, while a second connection interface is formed between the patterned photoresist layer and the under bump metallurgy layer. In the immerse step, the patterned photoresist layer contacts a chemical solution that degrades the bond strength of the first connection interface. Consequently, in the strip step, the semiconductor substrate is scoured by a flow with an appropriate force of impact, which strips the patterned photoresist layer from the base. Kuo-Hua Yang has 1 patent to his name.
