Abstract
A method and apparatus for assembling and packaging semiconductor die assemblies utilizes a coating element such as a wafer back side laminate formed on a back side of a semiconductor die is disclosed. The coating element may be formed from a somewhat compressible and, optionally, resilient material, which seals against a surface of a mold cavity while the semiconductor die assembly is being encapsulated. In this manner, the coating element prevents encapsulant material from covering at least a portion of the back side of the semiconductor die to prevent encapsulant flashing over the back side and thus improve heat dissipation characteristics of the packaged semiconductor die during operation.
