Mtech program of IIT-B is quite good if you want to do in India. One of my junior is doing Mtech in microelectronics from IIT B and many ex-IIT professors told him to go for it than IISc.
Now, actually i was doing Mtech from Amity University, Noida. after getting into it i realized it was not worth it, so left it in december. By that time admission lines of all good universities were closed.
Finished Btech, will be doing MS in Nanoelectronics. Applied in many universities, got selected in some premier British university, but reluctant to got there as their economy is in ****.
