Abstract
The present integrated circuit package provides both a high density of conductor poles, and reduced crosstalk noise between the conductor poles. The conductor poles are arranged within a selected number of holes in an insulating substrate. Metallized layers for shielding the conductor poles are provided on the walls of the holes in the insulating substrate which receive the conductor poles. In addition, an insulating layer is provided on the inner circumferences of the metallized layers, which insulating layers directly surround the conductor poles to preclude direct contact between the conductor poles and the metallized layers.
