Here you can see a list of wafers that we have on stock. Most of these are in the cupboard, called "B1 cage" (located inside the cleanroom, in room B1). Some of the wafers are stored in our basement and you must always contact DTU Nanolab personnel for buying these in advance. In the list you can see the specifications, prices as well as a link to a pdf file with more detailed information about the wafer specifications.

The door can be opened by twisting the handle counter clock wise. Please leave the door open while taking the wafers you have bought. After taking the wafers out of the box, place the wafer box back into the cupboard and close the door. This will enable lock the door again. | ||
Please note, when taking new wafers always use the dedicated vacuum tweezer hanging on the wall labeled Wafer Shop Tweezer. | |||
