T-ESC®

Semiconductor

The T-ESC® Technology by ProTec® offers safe and easy handling as well as processing of fragile, thin and ultra-thin substrates (thinner 50 µm), e.g. GaAs, InP, LN, LT, thin silicon, thin MEMS wafer and many more. The basic concept behind this adhesive free temporary bonding technology involves using electrostatic force to chuck thin and ultra-thin wafers onto mobile rigid Carriers (T-ESC®). Such wafer-Carrier packages can be handled and processed like wafers of standard thickness.

Therefore, existing standard cassettes, handling tools, and fabrication equipment can be used without modifications. Additional effect: the warping and bowing of thin and ultra-thin substrates are eliminated, which is highly welcome. All our Carriers are available in standard sizes from 2" to 12" and additionally in customized shapes suited to the intended application.
