Title: Innovator Che-Hao Kuo: A Pioneer in Physically Unclonable Functions and Flash Memory Technology

Introduction: Che-Hao Kuo is a notable inventor based in Tainan, Taiwan, recognized for his contributions to the field of semiconductor technology. With an impressive portfolio of three patents, Kuo has made significant strides in the development of methods for fabricating cutting-edge devices, particularly in the realm of physically unclonable functions (PUFs) and flash memory cells. His innovative work has the potential to enhance security and efficiency in electronic devices.

Latest Patents: Che-Hao Kuo's latest patents showcase his expertise in advanced semiconductor fabrication techniques. One of his notable inventions is a method for fabricating a physically unclonable function device. This process involves defining a PUF cell region on a substrate and creating intentional defects in that region. The creation of defects is preferably achieved through the establishment of shallow trench isolation (STI), followed by the deposition of a gate material layer that is patterned into two distinct gate materials, ultimately leading to the formation of an epitaxial layer that interconnects them.

Another significant patent involves the formation of a flash memory cell. Kuo's method details the sequential deposition of a first dielectric layer and a floating gate layer on a substrate. He introduces three blocking structures with oblique sidewalls that extend from the bottom to the top, which penetrate through both layers. The floating gate layer is etched to create two distinct floating gates, each featuring sharp corners and oblique sidewalls. The removal of the blocking structures is followed by the formation of isolating layers and selective gates, culminating in a sophisticated flash memory cell design.
