Abstract:
A multi layer interconnecting substrate has at least two spaced apart metal layers with a conductive pad on each one of the metal layers. Two different types of insulating layers are placed between the metal layers. The placement is such that one of the two different types of insulating layers is placed between the conductive pads and the other type of insulating layer is placed between the two spaced apart metal layers.
