Specific Process Knowledge/Back-end processing

Feedback to this page: click here

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.
