Abstract: A Chip-in Substrate Package (CiSP) includes a double-sided metal clad laminate including a dielectric interposer, a first metal foil laminated on a first side of the dielectric interposer, and a second metal foil laminated on a second side of the dielectric interposer. A recessed cavity is etched into the second metal foil and the dielectric interposer with a portion of the first metal foil as its bottom. A die is mounted within the recessed cavity and makes thermal contact with the first metal foil. A build-up material layer covers the second metal foil and an active surface of the die. The build-up material layer also fills the gap between the die and the dielectric interposer. At least one interconnection layer is provided on the build-up material layer and is electrically connected with a bonding pad disposed on the active surface of the die via a plated through hole.

Abstract: The present invention provides a method of manufacturing a double-sided printed circuit board. An insulation substrate is first formed by creating a plurality of through holes on a Copper Clad Laminate (CCL) whose copper foil surface has been removed. Next, an electro-less copper layer is plated on the substrate for forming a plurality of plated through holes. After a wire pattern is formed on the substrate, a solder preventive layer is formed on top of the wire pattern. Next, a plurality of openings is created in between the solder preventive layer for exposing the contact pads. Finally, a protective layer is plated on top of the contact pads.

Abstract: A packaging substrate is fabricated using two plating steps for respectively plating the gold-plating areas defined on two opposite sides of the substrate. Before plating, the gold-plating areas are defined by a layer of solder mask. By doing this, the plated gold layer will not overlap with the solder mask, thereby preventing peeling or reliability problems.
