Abstract:
To realize low-profile electronic apparatus (a memory module and a memory card) of a large storage size by mounting tape carrier packages (TCPs) with a memory chip encapsulated onto a wiring board in high density. To be more specific, a TCP is composed of an insulating tape, leads formed on one side thereof, a potting resin with a semiconductor chip encapsulated, and a pair of support leads arranged on two opposite short sides. The pair of support leads function to hold the TCP at a constant tilt angle relative to the mounting surface of the wiring board. By varying the length vertical to the mounting surface, the TCP can be mounted to a desired tilt angle.
Abstract:
This invention relates to three dimensional packaging of integrated circuit chips (306) into stacks to form cube structures. Between adjacent chips in the stack, there is disposed an electrical interconnection means which is a first substrate (300) having a plurality of conductors (316) one end of which is electrically connected to chip contact locations and the other end of which extends to one side of the chip stack to form a plurality of pin-like electrical interconnection assemblies. The pin-like structures (318) can be formed from projections of the first substrate having an electrical conductor on at least one side thereof extending from this side. Alternatively, the pin-like structures can be formed from conductors which cantilever from both sides of an edge of the first substrate corresponding conductors from both sides are aligned and spaced apart by the first substrate thickness. The spaces contains solder and form solder loaded pin-like structures. The pin-like structures can be directly solder bonded to conductors on a second substrate (302) surface or the pin-like structures can be adapted for insertion into apertures (320) in a second substrate. The second substrate provides a means for electrically interconnecting a plurality of these cubes. Preferably, the first and second substrates are circuitized flexible polymeric films. The second substrate is disposed on a third substrate, such as a PC board, with a resilient material therebetween which permits a heat sink to be pressed into intimate contact with an opposite side of the cube.
