LabAdviser

LabAdviser is a wiki that contains information about

• equipment at DTU Danchip that covers micro and nano fabrication in the cleanroom facility in building 346 and surroundings (in building 346 and 347) and electron microscopy at DTU CEN in building 314 and surroundings.
• fabrication steps in micro and nano fabrication that takes place at the cleanroom facility and surroundings and
• electron microscopy methods that takes place at the DTU CEN facility.

An overview of the equipment in these facilities can be found and some fabrication process flows and singles fabrication steps are described. In general LabAdviser is meant to advise you to the right equipment and to advise you to a good starting point for your micro and nano fabrication steps as for your electron microscopy work. This should not be replacing communication with the staff of the facilities but we recommend it as a good starting point before contacting the staff. To enter LabAdviser you need to log in with your DTU login. LabAdviser is only editable for the staff of the facilities. If you need further information about certain machinery or processes, please contact the relevant staff. Any feedback or input you might have to LabAdviser is welcome and can be given by mail to the LabAdviser mailbox: labadviser@danchip.dtu.dk
