ABSTRACT:
A method for creating an interface between a chip and chip carrier includes spacing the chip a given distance above the chip carrier, and then introducing a liquid in the gap between the chip and carrier. Preferably, the liquid is an elastomer which is hardened into a resilient layer after its introduction into the gap. In another preferred embodiment, the terminals on a chip carrier are planarized or otherwise vertically positioned by deforming the terminals into set vertical locations with a plate, and then hardening a liquid between the chip carrier and chip.
