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 a number of different places. We also have a laboratory called PackLab located in building 347 1st floor. It is a class 1000 cleanroom and in here we have equipment commonly used for back-end processing. Some equipment is further placed in the basement of building 346 and some on the 1st floor in building 346.

Below you can see a list of equipment for back-end processing that is available at DTU Nanolab.
