Patent ID: 7189601

Claim:
A compression molding method, comprising: positioning a film adjacent a first die structure such that a mold block coupled to the film is located in a die cavity in the first die structure, the mold block comprising mold compound and at least substantially holding its own shape; the cavity in the first die structure being wider than the mold block in a first direction such that one or more unfilled portions of die cavity exist around the mold block; positioning an integrated circuit structure adjacent a second die structure, the integrated circuit structure including one or more integrated circuit devices coupled to a substrate; moving the first die structure and the second die structure toward each other to cause the integrated circuit structure to compress the particular mold block within the die cavity in order to form a mold cap covering at least one of the one or more integrated circuit devices; and compressing the mold block causes the mold block to deform such that the mold compound of the mold block at least partially fills the one or more unfilled portions of the die cavity.
