A semiconductor stack and a semiconductor base device with a wiring substrate and an intermediate wiring board for a semiconductor device stack is disclosed. In one embodiment, a semiconductor chip is arranged between the intermediate wiring board and the wiring substrate which is electrically connected by way of the wiring substrate on the one hand to external contacts on the underside of the wiring substrate and on the other hand to contact terminal areas in the edge regions of the wiring substrate. The intermediate wiring board has angled-away external flat conductors, which are electrically connected in the contact terminal areas of the wiring board. Furthermore, on the upper side of the intermediate wiring board, arranged on the free ends of the internal flat conductors are external contact terminal areas, which correspond in size and arrangement to external contacts of a semiconductor device to be stacked.
Abstract:
An electronic component is disclosed including a plurality of semiconductor packages soldered together in a side-by-side configuration. The packages are batch processed on a substrate panel. The panel includes a plurality of through-holes drilled through the panel and subsequently filled with metal such as copper or gold. These filled through-holes lie along the cut line between adjacent packages so that, upon singulation, the filled through holes are cut and a portion of the filled through-holes are exposed at the side edges of the singulated packages. These exposed portions of the filled through-holes form vertical surface mount technology (SMT) pads. After the semiconductor packages are singulated and the SMT pads are defined in the side edges, SMT is used to solder the SMT pads of a first semiconductor package to the respective SMT pads of a second semiconductor package to structurally and electrically couple the two packages together side-by-side.

The object is the capability of providing a method of manufacturing mounting boards that enables extensive adoption of a stacked structure at a low cost. As a solution, in the method of manufacturing a mounting board in which a mounting board is manufactured by mounting a first electronic part 11 and a second electronic part 12 each having a solder bump in its bottom plane on a substrate 3 in stacked plural levels, after the first electronic part 11 is mounted on the substrate 3 that has been fed with solder, the solder bump 18 of the second electronic part 12 is mounted on the electrode 17 provided on the upper plane of the first electronic part 11, and thereafter the substrate 3 is heated in a reflow step to solder-bond the first electronic part 11 to substrate 3 along with solder-bonding the second electronic part 12 to the first electronic part 11. By such process, a stacked structure can be applied to a wide variety of electronic parts at a low cost.

Abstract:
Systems and methods for reducing switching noise in an integrated circuit. In one embodiment, decoupling capacitors are connected to the integrated circuit from the underside of the substrate on which the integrated circuit die is manufactured. The decoupling capacitors are positioned with a higher concentration in the “hot spot” areas of the integrated circuit instead of being evenly distributed. In one embodiment, the decoupling capacitors and the corresponding hole(s) in a circuit board on which the integrated circuit is mounted are positioned so that the circuit board provides support for the central portion of the integrated circuit and thereby prevents the integrated circuit from flexing away from the heat sink/spreader. In one embodiment, the concentration of vias connecting the different ground planes and/or power planes within the integrated circuit is higher in hot spots than in other areas.
