Thermal Coupler Equipping Service
It is very important for the Semiconductor manufacturing process and the LCD or OLED manufacturing process to control the surface temperature of the wafer and glass panels. We offer the service to equip a thin cable of thermal coupler to the wafer or glass panel, and also provide the measurement data of the temperature map of these products.
A difference between current service and our offered service
•We can supply a range of wafers including Silicon wafers, SiC wafers, Glass and Metal plates.
•We can provide custom made specifications as requested.
•We can also provide temperature measurement in a vacuum environment.
Film Deposited Wafer and Patterned Wafer
We also offer the service for various Film deposition and Pattern making on both 8inch and 12inch wafers.
