High performance integrated circuit packaging structure
First Claim
1. A high performance integrated circuit packaging structure comprising:
- a substrate;
alternating insulation and conductive layers on said substrate;
a plurality of internal circuits integrated into discrete semiconductor segments;
said discrete semiconductor segments mounted on an uppermost conductive layer;
said semiconductor segments placed in close enough proximity to each other so that performance is equal to that of a monolithic integrated circuit structure;
an array of feedthroughs in said substrate, a plurality of said feedthroughs located beneath said semiconductor segments;
wiring means incorporated into at least two of said conductive layers for providing connections for said internal circuits;
said wiring means being adapted for maintaining a noise voltage level in said integrated circuit structure which is substantially less than the lowest logic threshold voltage in said integrated circuit structure so that said plurality of internal circuit groups collectively have a number of drivers and receivers which is less than the number provided for by Rent'"'"'s Rule.

Abstract
A high speed, high performance integrated circuit packaging structure that may be used for emulating wafer scale integration structures. The preferred embodiment comprises an interposer having a base substrate having alternating insulation and conductive layers thereon, wherein a plurality of the conductive layers are wiring means which are adapted for maintaining an extremely low noise level in the package. The low noise level and low resistance and capacitance of the wiring means allows a plurality of discrete semiconductor segments to be mounted on and interconnected by the integrated circuit package with a significantly reduced number of drivers and receivers than required by Rent'"'"'s Rule. Each integrated circuit structure of the present invention emulates a large chip or wafer scale integration structure in performance without having to yield the large chip or wafer, and without redundancy schemes. A plurality of these integrated circuit packaging structures are combined by decals to form a central processing unit of a computer or a portion thereof. In an alternate preferred embodiment, the base substrate of the interposer is made of silicon and any required drivers are formed therein, thus substantially eliminating the need for any drivers on each of the discrete semiconductor segments.
