Patent ID: 6918178

Claim:
A method of manufacturing a plurality of IC (Integrated Circuit) packages each having an heat sink matrix integrally attached thereon, comprising the steps of: providing a communal substrate; attaching a plurality of semiconductor dies fixedly onto said communal substrate; providing the heat sink matrix; providing a molding apparatus, comprising: a lower mold half for holding said communal substrate with said semiconductor dies fixedly attached thereon; and a upper mold half for holding said heat sink matrix; wherein, said lower mold half and said upper mold half of the molding apparatus are combined in order to be filled by a melted molding material during a molding process and said heat sink matrix is held on said upper mold half by means of vacuum suction; placing said communal substrate with said semiconductor dies fixedly attached thereon and said heat sink matrix into said molding apparatus; filling the melted molding material into said molding apparatus to collectively encapsulate said semiconductor dies fixedly attached on said communal substrate and said heat sink matrix thereby forming an IC package matrix integrated with said heat sink matrix after said molding material is permanently set; extracting said IC package matrix integrated with said heat sink matrix from the molding apparatus; and dividing said IC package matrix integrated with said heat sink matrix into said IC packages each having said heat sink integrally attached thereon.
