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 20):
A method of forming a 4D integration circuit system comprising the steps of:\n coating an upper surface of at least four wafers with a layer of CNT/polymer composite; bonding said wafers to form a stack comprising said wafers and said CNT/polymer composite, said stack having an edge; flipping said stack to rest upright on said edge; attaching a chip to said edge; said CNT/polymer base composite being compatible with a metal contact pad and having high thermal conductivity and a temperature stability of at least 350\u00b0 C. said polymer selected from the group consisting of polyimides, polybenzazole, polybenzoxazoles, polyimidazoles, polybenzimidazoles, polyarylenes, polyarylene ethers, polyetheretherketones, polyarylether ketones and polynorbornenes and being in admixture with a plurality of carbon nanotubes (CNT), wherein, in order achieve an optimum level of bond strength and thermal conductivity, a loading level of said CNT in said polymer base resin ranges from about 30% by volume to about 80% by volume, a length scale of said CNTs being substantially equal to a final bonded adhesive layer thickness so as to maximize said CNT's straddling an adhesive bond line with said length scale of said CNT, said admixture containing or in contact with between about 0.1% and 1% of an adhesion promoting coupling agent is selected from the group consisting of (3-aminopropyl)triethoxysilane, p-aminophenyltrimethoxysilane, 3-[2-(2-aminoethylamino)ethylamino]propyl-trimethoxysilane, 4-Ti[2-propanolato-tris(3,6-diaza)]hexanolato, 3-methacryloxy-propyl-trimethoxysilane, vinyl I-trimethoxysilane, 3-isocyanate-propyl-triexthoxysilane, mercapto-propyltrimethoxysilane, 3-amino-propyl-triethoxysilane and 3-methacryloxy-propyl-trimethoxysilane.
