Abstract:
A semiconductor die and a retaining fixture used during burn-in operations for said semiconductor die, said assembly comprising:a semiconductor die having a first side having at least one bond pad thereon and a second side; a fixture having a cavity having a bottom surface for temporarily retaining said semiconductor die therein during said burn-in operations, said fixture including at least one contact pad located on a surface of said fixture other than said bottom surface for connection to said at least one bond pad on said semiconductor die, said bottom surface having a hole extending therethrough for use in removal of said semiconductor die from said fixture; a piece of tape having an adhesive coating on each side thereof for temporarily retaining said semiconductor die in said cavity in said fixture, said piece of tape located in said cavity in said fixture, said piece of tape temporarily secured to said second side of said semiconductor die and temporarily secured to said bottom surface of said cavity of said fixture covering said hole extending through said bottom surface of said cavity of said fixture, said piece of tape having a maximum working temperature of at least 155Â° C.; and at least one lead wire directly connecting said at least one bond pad of said semiconductor die to said at least one contact pad of said fixture.
