LabAdviser

LabAdviser is a process handbook for equipment and processes at the DTU Danchip cleanroom facilities. The function and capacity of each piece of equipment is described in detail and general process steps, eg photolithography procedures, are clarified. LabAdviser is meant to advise you to a good starting point for your cleanroom process for further optimization to meet your needs. To enter LabAdviser you need to log in with your DTU login. LabAdviser is only editable for Danchip employees. If you need further information about certain machinery or processes, please contact the Danchip personnel. Any feedback you might have on LabAdviser is welcome and can be given by mail to the LabAdviser mailbox: labadviser@danchip.dtu.dk
