Abstract:
1. A layout of a printed circuit board, adaptive to be bonded to an integrated circuit device, the layout comprising: a first metal layer, disposed in a first insulation layer; and a second metal layer, disposed in a second insulation layer over the first insulation layer, wherein the first metal layer and the second metal layer are connected to each other through a plurality of contact hole filled with conductive materials and are arranged to be substantially parallel to each other throughout a pad structure region and a line structure region of the printed circuit board, wherein the connected first metal layer and second metal layer are used for a signal path from the printed circuit board to the bonded integrated circuit device, and wherein in the pad structure region, the second metal layer is exposed and an Indium Tin Oxide (ITO) layer is disposed on the second metal layer.
