What EE specializations are these schools known for? Caltech vs UC Berkelet vs UCLA vs UCSD vs UM-Ann Arbor vs UIUC

Hi! UCLA EE undergrad student here. I applying to MS EE/EECS degree for Fall 2020. I am applying to the schools listed below. I heard that UCLA is known for its signal and system (?), but not 100% sure.  I am wondering what EE/EECS specializations are these schools known for:

1. Caltech

2. UC Berkeley

3. UCLA

4. UC San Diego

5. UM-Ann Arbor

6. UIUC

I am currently interested in VLSI, circuits, robotics, medical devices (I know... I will narrow it down...), any other suggestions for grad school would be great! Thanks in advance!
