Claim 25:
26. A method for forming a semiconductor device assembly, the method comprising:
adhering, above a surface of a semiconductor die, an anisotropic conductive film structure, 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;

adhering, above the anisotropic conductive film, a surface of an other semiconductor die; and
compressing the anisotropic conductive film between the semiconductor die and the other semiconductor die to displace at least some of the adhesive dielectric material and directly contact at least some of the discrete conductive regions with conductive structures spaced along the surface of the semiconductor die and with other conductive structures spaced along the surface of the other semiconductor die.
