Lectures

Lectures at the Institute for Large Area Microelectronics

Important!!! Online teaching

Due to the special situation caused by the novel corona virus teaching will continue to take take place online. The contents of all lectures and exercises will be available via ILIAS as .mp4 files just as they have been during the past semesters.

As of now the lab course "Flat Panel Displays" will take place as a regular offline lab course.
