I think you're using the college in the UK sense and dylz meant "college as in undergraduate study institution, where you get your first degree". but I might be wrong. Also I've hardly heard of independent institutions joining universities here in Germany. Maybe you thought of the Hasso Plattner Institute "HPI was founded in 1998 and is the first, and as of 2018 the only entirely privately funded faculty[3] in Germany." So the University of Potsdam has a private IT faculty.
