INTEGRATED CIRCUIT WIRE BONDED TO A MULTI-LAYER SUBSTRATE HAVING AN OPEN AREA THAT EXPOSES WIRE BOND PADS AT A SURFACE OF THE INNER LAYER

Abstract:

An apparatus includes an integrated circuit and a substrate coupled to the integrated circuit. The substrate includes a primary layer having a first surface that is a first external surface of the substrate. The primary layer includes an open area that extends through the primary layer to an inner layer of the substrate. The substrate includes a secondary layer. The inner layer is located between the primary layer and the secondary layer. The inner layer includes a third surface that is orientated approximately parallel to the first surface of the primary layer. A portion of the third surface of the inner layer is exposed via the open area of the primary layer. A first plurality of wire bond pads are disposed on the portion of the third surface of the inner layer that is exposed via the open area of primary layer.
