Wafer Information
DTU Danchip has a stock of silicon and glass wafers; the most used of these wafers are located on the wafershelves in cleanroom 2. Whenever you take a wafer from stock, you should buy the wafer from the wafer shop in LabManager. The Price can also be found in the wafer shop.
The waferbox name consists typically of a few letters and a number, eg OP337:
