摘要：A semiconductor mounting system is provided for the detachable surface mounting of one or more semiconductor dies on a conductor substrate, such as a ceramic substrate or printed circuit board. The system employs a resilient, anisotropic conductor pad which is interposed between the semiconductor die and the conductor substrate. The conductor pad is capable of conducting electric signals in one direction only, and insulates in the other two orthogonal directions. Thus, by compressing the semiconductor die and resilient conductor pad against the conductor substrate, electrical contact is established between contacts on the semiconductor die and corresponding contacts on the conductor substrate. In the preferred embodiment, additional conductor pads are placed over the semiconductor dies, and a heat sink placed over the second conductor pads. In this way, the semiconductor dies are mounted in a resilient structure for protection, while heat dissipation is enhanced by the metallic elements in the second conductor pad.
