Abstract:
A method of testing a semiconductor chip using a separable connection, comprising the steps of:providing a semiconductor chip having contact pads located in an arrangement on a surface of the semiconductor chip;placing an electrically conductive adhesive material and a precious metal layer on the contact pads, so that the precious metal layer is between the contact pads and the electrically conductive adhesive material;providing a test substrate having conductive test pads located on a surface of the test substrate in a mirror image pattern corresponding to the arrangement of the contact pads;moving the semiconductor chip and the test substrate together, aligning the electrically conductive adhesive with the test pads, and applying a predetermined force;testing the semiconductor chip;moving apart the semiconductor chip and the test substrate;removing the electrically conductive adhesive material from the contact pads of the semiconductor chip.
