Claim:
1. A method of fabricating a microelectronic device comprising: forming a microelectronic substrate having a plurality of microelectronic device attachment bond pads and at least one interconnection bond pad formed in and/or on an active surface thereof; attaching a microelectronic device to the plurality of microelectronic device attachment bond pads; forming a mold chase having a mold body and at least one projection extending from the mold body, wherein the at least one projection includes at least one sidewall and a contact surface, and wherein the at least one projection includes a portion comprising a resilient material that is different from the material of the remainder of the at least one projection, and wherein the portion of the at least one projection includes the mold chase projection contact surface; contacting the at least one mold chase projection contact surface to a respective microelectronic substrate interconnection bond pad; disposing a mold material between the microelectronic substrate and the mold chase; and removing the mold chase to form at least one interconnection via extending from a top surface of the mold material to a respective microelectronic substrate interconnection bond pad.
