Patent ID: 7192804

Claim:
A method for fabricating a semiconductor device, said method comprising the steps of: (a) forming bonding pads above a wafer on which semiconductor elements and an interconnect layer are formed; (b) forming a passivation film having apertures including regions of the passivation film located above parts of the bonding pads and scribe line regions after the step (a); (c) forming a buffer coat film for covering part of the passivation film after the step (b), and removing a region of the buffer coat film extending from an edge of the wafer and located on the whole periphery region having a certain distance from the periphery of the wafer; (d) forming, in the buffer coat film, apertures including regions of the buffer coat film above the scribe line regions and above the parts of the bonding pads, respectively; (e) bonding a surface protection tape to the wafer using an adhesive material which contacts the passivation film in the whole periphery region of the wafer after the step (d); and (f) polishing the rear surface of the wafer after the step (e).
