A capacitive interposer (caposer) is disposed inside an integrated circuit package between a die and an inside surface of the package. Conductive layers within the caposer constitute a bypass capacitor. In a through-hole caposer, micro-bumps on the die pass through through-holes in the caposer and contact corresponding landing pads on the package. As they pass through the caposer, power and ground micro-bumps make contact with the plates of the bypass capacitor. In a via caposer, power and ground micro-bumps on the die are coupled to power and ground landing pads on the package as well as to the plates of the bypass capacitor by power and ground vias that extend through the caposer.

Sealed cell having non-resealable safety valve
ActiveUS20050112455A1Thicker valve structureReduce decreaseNon-aqueous electrolyte accumulatorsNon-aqueous electrolyte cellsInternal pressureEngineering
A sealed cell having a safety mechanism is provided. The safety mechanism has a non-resealable valve structure formed in a sealing plate that seals the cell. The valve structure is broken as soon as the internal pressure reaches or exceeds a predetermined value so as to permit the internal gas to be released outside. The valve structure has at least one dome protruding toward the interior of the cell, which in turn has at the periphery thereof a break groove for facilitating the breakage of the valve structure. This makes the valve structure highly responsive to the internal pressure and causes to form a break-opened orifice of a sufficient area at the time of operation in response to the increased internal pressure. The valve structure is not unnecessarily broken by the impacts of, for example, dropping. As a result, the safety of the sealed cell is significantly improved.
