Abstract:
The present invention discloses the use of a dielectric substrate panel suitable for supporting a plurality of independently packaged ICs. The substrate panel has a plurality of conductive landings arranged on its top surface, a plurality of conductive contacts arranged on its bottom surface and a multiplicity of electrically conductive vias. The vias pass through the substrate panel and are arranged to interconnect selected landings with their associated conductive contacts. The top surface of the substrate panel also includes a number of die attach areas. During packaging, dies are secured to their associated die attach areas on the substrate panel and electrically coupled to appropriate conductive landings. An encapsulant is then formed over each of the dies for protection.

Abstract:
A shielding assembly is configured to provide electromagnetic shielding and environmental protection to one or more electronic components coupled to a substrate. The shielding assembly includes a non-conductive mold compound layer, such as a dielectric epoxy. The mold compound layer is applied to a top surface of the substrate, thereby covering the electronic components and providing protection against environmentally induced conditions such as corrosion, humidity, and mechanical stress. The shielding assembly also includes a conductive layer applied to a top surface of the mold compound layer. The conductive layer is coupled to a ground plane in the substrate, thereby enabling the electromagnetic shielding function. The conductive layer is coupled to the ground plane via one or more metallized contacts that are coupled to the substrate and extend through the mold compound layer.
Abstract:
A structure and method of manufacture for an improved multi-chip semiconductor package that reduces package resistance to a negligible level, and offers superior thermal performance. Housing of multiple dies is facilitated by providing electrically isolated lead frames that are separated from a common base carrier by a non-conductive layer of laminating material. A silicon die is attached inside a cavity formed in each lead frame. Direct connection of the active surface of the silicon die to the printed circuit board is then made by an array of solder bumps that is distributed across the surface of each die as well as the edges of the lead frame adjacent to each die.

Abstract:
A method for forming a stud bumped semiconductor die is disclosed. The method includes forming a ball at the tip of a coated wire passing through a hole in a capillary, where the coated wire has a core and an oxidation-resistant coating. The formed ball is pressed to the conductive region on the semiconductor die. The coated wire is cut, thereby leaving a conductive stud bump on the conductive region, where the conductive stud bump includes an inner conductive portion and an outer oxidation-resistant layer.
