Abstract
An integrated circuit package substrate includes a first and an additional electrically conductive layer separated from each other by an electrically insulating layer, a contact pad formed in the first electrically conductive layer for making a direct connection between the integrated circuit package substrate and a printed circuit board, and a cutout formed in the additional electrically conductive layer wherein the cutout encloses an area that completely surrounds the contact pad for avoiding parasitic capacitance between the additional electrically conductive layer and the printed circuit board.
