Back-end (or Post-fab) Processing are typical processes used to finish up your wafer/chip. This includes thinning and cutting out the wafer in chips that can be put on a carrier, a board or in a package, attaching the chip to the carrier and connecting it with wires to get electrical access to it.

These processes are usually carried out outside the clean room. At Danchip we have a laboratory called Packlab located in building 347 1.st floor. It is a class 1000 cleanroom and in here we have equipment commonly used for back-end processing.
