Abstract:
A semiconductor device, comprising:a semiconductor chip having a plurality of electrode pads formed on a peripheral portion of a front surface of the semiconductor chip, an effective device region occupying an interior of the peripheral portion;an insulating, thick film protective layer laminated on the effective device region of the semiconductor chip, said insulating thick film protective layer entirely covering the effective device region; anda semiconductor chip package in which said semiconductor is secured, said semiconductor chip package including:a) a plurality of leads comprised of outer leads and inner leads integral with and extending from the outer leads, the inner leads having tips connected to the electrode pads of the semiconductor chip;b) an insulating film protecting the outer leadsc) external connection terminals formed on the outer leads;d) a reinforcement plate provided so as to surround the semiconductor chip; ande) a sealing resin filling in a peripheral space between the semiconductor chip and a portion of the semiconductor chip package within which the semiconductor chip is secured;wherein both surfaces of the insulating, thick-film protective layer parallel to the front surface of the semiconductor chip are resin-free, and wherein said effective device region is resin-free.
