DTU Nanolab has a stock of standard silicon and glass wafers, as well as somes wafers pre-processed in one of our thermal furnaces. The most commonly used wafers are located in the wafer cupboard in cleanroom B-1. DTU Nanolab always tries to have new deliveries of wafers on stock. They will be available when the previous delivery has been used. Other substrates have to be purchased personally, though you are very welcome to ask us for help if needed.
