Abstract:
The present invention relates to CNT filled polymer composite system possessing a high thermal conductivity and high temperature stability so that it is a highly thermally conductive for use in 3D and 4D integration for joining device sub-laminate layers. The CNT/polymer composite also has a CTE close to that of Si, enabling a reduced wafer structural warping during high temperature processing cycling. The composition is tailored to be suitable for coating, curing and patterning by means conventionally known in the art.

Claim (Index 13):
A method of forming a 3D integration circuit system comprising the steps of:\n Forming a top wafer and a bottom wafer into a stack by; affixing a conductive metal key to an underside of said top wafer; etching a trench in an upper surface of a bottom wafer; inserting a metal contact in said trench; coating an oxide insulation covering said metal contact and said upper surface of said bottom wafer; coating said an upper surface of said oxide insulation with a high temperature polymer composite fill; applying a lithographic pattern to an upper surface of said high temperature polymer composite fill and etching a trench through said high temperature polymer composite fill to said metal contact to form a lock; coating said underside of said top wafer and exposed portions of said key with said high temperature polymer composite; removing a portion of said high temperature polymer composite that encapsulates a terminal end of said key to expose said terminal end; inserting said key into said lock to form a lock and key bond wherein said terminal end of said key is in contact with said metal contact in said lock.
