Classification: CPC H | IPC H

Claim 11:
12. A semiconductor device assembly, comprising:
a semiconductor die comprising conductive structures spaced along a surface of the semiconductor die;
an other semiconductor die comprising other conductive structures spaced along a surface of the other semiconductor die; and
an anisotropic conductive film structure interposed between the surface of the semiconductor die and the surface of the other semiconductor die, the anisotropic conductive film structure comprising:
an array of discrete conductive regions within a continuous region of at least one adhesive dielectric material, the discrete conductive regions of the array being mutually laterally spaced from one another by at least one predetermined pitch, at least some of the discrete conductive regions each comprising:
a conductive carbon-based material, the conductive carbon-based material defining a void space therein; and
a seed material extending along vertical sidewalls of the conductive carbon-based material and along only one of an uppermost surface and a lowermost surface of the conductive carbon-based material.
