Abstract
A method of using adhesive tape to temporarily retain a die being temporarily held in a fixture during testing and burn-in. The method of the present invention uses a die cut piece of adhesively coated tape to hold a die in a test and burn-in fixture. Upon subsequent heating of the tape beyond the normal operating range of the adhesive coating on the tape, the die is removed from the tape, the tape is removed from the test and burn-in fixture, and the remaining adhesive, if any, is removed from the test and burn-in fixture.
Claims51
A method of retaining a semiconductor die in a fixture to perform operations on said semiconductor die, said method comprising:
- providing said fixture;
- providing tape having adhesive on at least one side thereof;
- cutting a piece of the tape having a size to fit in said fixture;
- transferring the piece of the tape to said fixture;
- placing said semiconductor die on the piece of the tape transferred to said fixture;
- adhesively securing one of said fixture and said semiconductor die by the adhesive on at least one side of the piece of the tape:
- performing operations on said semiconductor die when mounted in said fixture;
- removing said semiconductor die from said fixture after performing said operations on said semiconductor die;
- and
- removing the piece of the tape from the fixture after the performing of said operations on said semiconductor die in said fixture.
A method of retaining a semiconductor die in a fixture to perform testing and burn-in operations on said semiconductor die, said method comprising:
- providing said fixture;
- providing tape having adhesive on at least one side thereof;
- cutting a piece of the tape having a size to fit in said fixture;
- transferring the piece of the tape to said fixture;
- placing said semiconductor die on the piece of the tape transferred to said fixture;
- adhesively securing one of said fixture and said semiconductor die by the adhesive on at least one side of the piece of the tape;
- performing said testing and burn-in operations on said semiconductor die when mounted in said fixture;
- removing said semiconductor die from said fixture after the performing of said testing and burn-in operations on said semiconductor die;
- and
- removing the piece of the tape from the fixture after the performing of said testing and burn-in operations on said semiconductor die in said fixture.
A method of securing a semiconductor die in a cavity of a fixture for performing operations on said semiconductor die, said method comprising the steps of:
- cutting a piece of tape having an adhesive coating thereon;
- transferring the piece of tape to said cavity of said fixture;
- and
- inserting said semiconductor die in said cavity of said fixture wherein the piece of tape retains said semiconductor die in said cavity.
A method of retaining a semiconductor die in a fixture to perform operations on said die, said method comprising:
- providing said fixture;
- providing tape having adhesive on each side thereof;
- cutting a piece of the tape having a size to fit in said fixture;
- transferring the piece of the tape to said fixture;
- placing said semiconductor die on the piece of the tape transferred to said fixture;
- adhesively securing said fixture and said semiconductor die by the adhesive on each side of the piece of the tape;
- performing operations on said semiconductor die when mounted in said fixture;
- removing said semiconductor die from said fixture after performing said operations on said semiconductor die;
- and
- removing the piece of the tape from the fixture after the performing of said operations on said semiconductor die in said fixture.
A method of retaining a semiconductor die in a fixture to perform testing and burn-in operations on said die, said method comprising:
- providing said fixture;
- providing tape having adhesive on each side thereof;
- cutting a piece of the tape having a side to fit in said fixture;
