Classification: H01L

Abstract:
A semiconductor device comprising:a semiconductor chip which has multiple electrode pads on the main plane;an insulating film which has an opening smaller than the main plane of the aforementioned semiconductor chip and is arranged in such a way that the opening is positioned on the aforementioned main plane;an inner lead part which is a conductor pattern comprised of multiple leads formed on the aforementioned insulating film and has each of the leads extended into the opening of the aforementioned insulating film and connected to an electrode on the chip;an outer lead part which is extended to the outside from the inner lead part; multiple support bumps which are positioned between the main plane of the aforementioned semiconductor chip and the aforementioned insulating film to form a gap between the main plane and the plane opposite the aforementioned main plane of the insulating film;an elastic film which is formed on the aforementioned insulating film on the side opposite the main plane of the aforementioned semiconductor chip; anda potting resin which is used to cover the opening of the aforementioned insulating film.
