Abstract:
A method for packaging a semiconductor device assembly, comprising:providing a semiconductor device assembly including at least one semiconductor die having an active surface and a carrier therefor positioned adjacent to the active surface; applying a coating element defining an outer periphery to a backside of the at least one semiconductor die; positioning the semiconductor device assembly within a cavity of a mold, with the coating element between the backside of the at least one semiconductor die and an inner surface of the cavity; compressing the coating element between the inner surface of the cavity of the mold and the backside of the semiconductor die from an initial thickness prior to compressing to a second, reduced thickness at least during compressing; and introducing an encapsulant into the cavity to encapsulate at least a periphery of the at least one semiconductor die while preventing encapsulant flash over a portion of the backside of the at least one semiconductor die within the outer periphery of the coating element.
