Patent ID: 7687320

Claim:
A method for manufacturing a semiconductor device, comprising: a passivation film formation step of forming a passivation film on a main surface of a semiconductor chip including circuit elements and on electrode pads formed on said main surface; a removal step of removing a part of said passivation film so as to expose a first region of said main surface along an outer peripheral edge of said main surface so that an outer peripheral edge of said passivation film abuts said first region; an insulating film formation step of forming an insulating film covering said first region and said passivation film so as to have a step surface corresponding to said outer peripheral edge of said passivation film, and partially removing said insulating film on the basis of said step thereof, the partially removed insulating film extending over top and side surfaces of said passivation film and partially onto the exposed first region of said main surface, such that a second region within said first region is exposed along said outer peripheral edge of said main surface; and a sealing layer formation step of forming on said second region a sealing layer which covers said partially removed insulating film.
