Courses

We are building up a number of courses to educate our users in using the cleanroom facility and the equipment inside. Below you can see the courses that are presently running. The "Cleanroom introduction Course" is mandatory for all users that need to enter the cleanroom facility on their own. Then there is a number of TPT's (Tool Package Training Courses) that you need to attend depending on which kind of tool you need to use inside the facility.

The Cleanroom Introduction Course

For information regarding the Introduction Course, please take a look at the DTU Danchip homepage, a direct link is given here: [1]
