A method of physically and electrically joining two chips to each other includes aligning a conductive contact of a first chip with a corresponding conductive contact on a second chip; the conductive contact of a first chip is rigid The conductive contact of the second chip is a malleable material; contacting the aligned conductive contact of the first chip with the corresponding conductive contact on the second chip; While applying pressure to the chip to penetrate the malleable material and form a conductive connection, the chip contacts are brought to a temperature below the liquidus temperature of both the rigid material and the malleable material. Raising the temperature; and, following the formation of the conductive connection, cooling the contacts to ambient temperature. |
