Abstract:
One embodiment of the invention is a semiconductor system (1400) of arrays (1401, 1402, etc.) of packaged devices. Each array includes a sheet-like substrate (1411, 1412, etc.) made of insulating material integral with conductive horizontal lines and vertical vias, and terminals on the surfaces. Semiconductor components, which may include more than one active or passive chips, or chips of different sizes, are attached to the substrate; the electrical connections may include flip-chip, wire bond, or combination techniques. Encapsulation compound (1412, 1422, etc.), which adheres to the substrate, embeds the connected components. Metal posts (1431, 1432, etc.) traverse the encapsulation compound vertically, connecting the substrate vias with pads on the encapsulation surface. The pads are covered with solder bodies used to connect to the next-level device array so that a three-dimensional system of packaged devices is formed.
Abstract:
Two or more semiconductor dies (102, 104) are electrically connected by connections 106 and encapsulated in a wafer scale package. A first die 102 enclosed in a wafer scale package is adapted and configured to mate with a printed circuit board (108) via solder bump (110). A second die 104 enclosed in a wafer scale package is electrically connected to a surface of the first die facing the board (108) to form a die stack.
Abstract:
A plastic package (100) in which a semiconductor chip (101) is attached with adhesive (102) to a metal stripe (110a) having an agglomerate structure, and electrically connected to bondable and solderable metal stripes (120) having particulate structures; metal stripes (120) are touching metal stripes (110b) of agglomerate structure to form vertical stacks. Coats of solder (140) are welded to the agglomerate metal stripes (110a and 110b).
Abstract:
A self-leveling heat sink includes a spring-arm device having at least one aperture and at least one spring-arm is coupled to a substrate. The substrate has at least one package mounted thereon, so that when the spring-arm device is mounted to the substrate the at least one package passes through the at least one aperture. A heat sink operable to remove heat from the at least one package has at least one heat sink post operable to receive a heat sink clip located at the distal end of each of the at least one spring-arms. Each of the at least one spring-arms extending from an inside edge of the at least one aperture and operable to couple the heat sink to the at least one package.
