A tape bonding system may include a tape and a lead coupled to the tape. The lead may have a stress relief formed along its length which is adapted to relieve stresses and strains arising from differential thermal expansion of the materials to which the tape is coupled. The lead may have a first portion supported by the tape and a second portion which is unsupported by the tape due to an opening in the tape. The unsupported portion of the tape may be deflected to make contact with a bond pad. In this configuration, the lead may accommodate differential thermal expansion by cantilevered beam displacements. In addition, due to the provision of a stress relief, the beam can respond in a totally different rotational displacement to compressive stresses parallel to the surfaces of the integrated circuit elements being joined.

A vertically mountable semiconductor device including a plurality of stub contacts extending perpendicularly from a bottom edge thereof. A complementary alignment device includes a receptacle for receiving the vertically mountable semiconductor device. The alignment device is attachable to a carrier substrate. Upon attachment of the alignment device to a carrier substrate and insertion of a vertically mountable semiconductor device into the receptacle, a contact element applies a downward force to the vertically mountable semiconductor device to establish and maintain an electrical connection between the vertically mountable semiconductor device and the carrier substrate.
摘要:
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.

The present invention is directed to a method of attaching a leadframe to a singulated good die using a wet film adhesive applied in a predetermined pattern on the active surface of the good die, the lead finger of a leadframe, or both. By applying the adhesive only to identified good dice, time and material are saved over a process that applies adhesive to the entire wafer. By attaching the leadframe to the good die with a wet film, it is possible to remove the leadframe from the good die for rework if the good die subsequently tests unacceptable.
