Semiconductor
The T-ESC® Technology by ProTec® offers safe and easy handling as well as processing of fragile, thin and ultra-thin substrates (< 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.
