Abstract: An interposer having decaps formed in blind-vias, a packaged semiconductor structure having decaps formed in blind-vias, and methods for forming the same are provided. In one embodiment, an interposer is provided that includes an interconnect layer disposed on a substrate. A plurality of through-vias are formed through the substrate in an isolated region of the substrate. At least one of the plurality of conductive vias are electrically coupled to at least one of a plurality of top wires formed in the interconnect layer. A plurality of blind-vias are formed through the substrate in a dense region of the substrate during a common etching step with the through-vias. At least one blind-via includes (a) a dielectric material lining the blind-vias, and (b) a conductive material filling the lined blind-vias and forming a decoupling capacitor.

Abstract: Embodiments of the present provide an integrated circuit system, which includes an interposer having a plurality of electrical conductive vias running through the interposer, one or more high-power chips mounted on a first surface of the interposer, wherein the one or more high-power chips generate at least 10 W of heat during normal operation, one or more low-power chips mounted on a second surface of the interposer, wherein the one or more low-power chips generate less than 5 W of heat during normal operation, and the first surface and the second surface are opposite and substantially parallel to each other, and an encapsulating material formed over and configured to encapsulate the one or more high-power chips and the one or more low-power chips. Since low-power chips and high-power chips are respectively mounted on front side and back side of the interposer, the footprint of the interposer and manufacturing cost associated therewith is reduced.

Abstract: An IC system includes low-power chips, e.g., memory chips, located proximate one or more higher power chips, e.g., logic chips, without suffering the effects of overheating. The IC system may include a high-power chip disposed on a packaging substrate and a low-power chip embedded in the packaging substrate to form a stack. Because portions of the packaging substrate thermally insulate the low-power chip from the high-power chip, the low-power chip can be embedded in the IC system in close proximity to the high-power chip without being over heated by the high-power chip. Such close proximity between the low-power chip and the high-power chip advantageously shortens the path length of interconnects therebetween, which improves device performance and reduces interconnect parasitics in the IC system.

Abstract: A gate array is disclosed having a programmable polysilicon layer which serves as both the gate electrodes for MOS transistors and routing lines for some connections between gate electrodes. The gate array structure is formed on a semiconductor substrate and has an array of identical base cells located in a core region of the structure. Each such base cell des the following elements: (1) a plurality of transistors, each of which includes a gate electrode; and (2) one or more gate connection strips formed on the substrate and electrically connecting selected gate electrodes of two or more of the transistors. Preferably, the gate connection strips are made from the same material as the selected gate electrodes (e.g., polysilicon) and are integrally connected therewith. The gate connection strips may patterned (i.e., programmed) to form substrate level routing between gates of various transistors.

Abstract: A package for a semiconductor chip is provided which incorporates a plurality of levels of interconnect--conductive layers within the package which selectively direct signals to and from pins of the die and/or the pins of the package. A single general purpose chip may thus be fabricated in large quantities with the interconnect of the package used to define the specific purpose, functionality and pinout of the final device. Similarly, a standard package may be built to work with a large class of different chips and only the interconnect layers in the package need to be modified to allow the package to work with each different chip. In a second aspect of the invention, one or more layers of interconnect in the package may contain active electronic components which may be connected to nodes of the chip through the interconnect of the package and through the pins of the die.

Abstract: A radiation hardened MOSFET is fabricated by forming a dielectric layer of boro-phosphosilicate glass (BPSG) over the field oxide layer of the MOSFET. The BPSG covers only a small part of the gate electrode of the MOSFET. The gate electrode of the MOSFET is formed from two layers of polycrystalline silicon so as to prevent contamination of the gate oxide by the BPSG dopants.
