Abstract:
1. A mold assembly configured for use in packaging a semiconductor die on a carrier, the mold assembly comprising: at least first and second mold sections to be assembled with one another; at least one cavity segment formed in each of the first and second mold sections, the at least one cavity segment in each of the first and second mold sections being sized and configured, when in alignment, to define at least one cavity configured to receive a semiconductor die on a carrier; and an enhanced portion of an inner surface of the at least one cavity segment of at least one of the first and second mold sections comprising a surface finish of enhanced smoothness relative to at least one other portion of the inner surface; wherein the enhanced portion of the inner surface is sized and configured to abut and form a seal with at least a portion of a coating element at substantially the outer periphery of a back side of the semiconductor die received in the at least one cavity.
