APPLICATIONS

Temperature control unit of semiconductor FAB process

Semiconductor manufacturing is a process with extremely high environmental requirements, and many process steps are very sensitive to temperature.
Precise temperature control can ensure uniform thickness and accurate composition of deposited films, thereby improving chip performance and yield.

for Semiconductor packaging & testing process

Semiconductor packaging and testing process is a key link in the semiconductor production process, including wafer testing, chip packaging and post-packaging testing. This process requires not only a high degree of accuracy and reliability, but also strict temperature control to ensure product quality and performance.
