Physimeca

The Physicmeca, Located in cleanroom B-1.

Physimeca is a system for deposition of metals through electron-beam evaporation.


Wafers are loaded into the system through the load lock and transferred into the deposition chamber. Physimeca allows you to deposit metals on samples up to 4 inch wafer. There are three different sample holders, one for chips (arbitrary size), one for 2" wafers and one for 4" wafers. The sample holder can be tilted during deposition, but is normally kept in a horizontal orientation.

Six different metals are present at each time in the Physimeca. The metal combination is changed if needed. A list of currently allowed metals is included in the table below; contact the ThinFilm team (Metal@nanolab.dtu.dk) if you have wishes for other metals.


The user manual and contact information can be found in LabManager:
