30. A composite wafer comprising:
-
a semiconductor substrate comprising a plurality of at least partially unsingulated chips, each chip comprising (i) a plurality of exposed electrical contact pads and (ii) a non-contact region disposed between the electrical contact pads; and an anisotropic conductive adhesive (ACA) on the semiconductor substrate and contacting the electrical contact pads and at least a portion of the non-contact region of each chip, wherein (i) none of the electrical contact pads comprises a solder bump or a non-solder bump, and (ii) no solder bumps or non-solder bumps are disposed between the electrical contact pads and the ACA. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51)
