摘要:
A chip package is described (450). This chip package includes a stack of semiconductor dies (110-1,110-2,110-N) or chips that are offset from each other, thereby defining a terrace with exposed pads. A ramp component (112), which is positioned approximately parallel to the terrace, electrically couples to the exposed pads. Mechanical stops (460-1) are formed on respective semiconductor die for mechanical contact between the semiconductor die and the ramp component. The ramp component is electrically coupled to the semiconductor dies using microsprings (114). Consequently, the electrical contacts may have a conductive, a capacitive or, in general, a complex impedance. By removing the need for costly and area-consuming through-silicon vias ( TSV s) in the semiconductor dies, the chip package facilitates chips to be stacked in a manner that provides high bandwidth and low cost.

An electronic component storing package which generates a large quantity of heat during operation and an electronic apparatus storing such an electronic component are provided. In the electronic component storing package and the electronic apparatus, a heat dissipating member (1) is used which comprising at least five layers including first metal layers (11) having good thermal conductivity and second metal layers (12) having a smaller coefficient of thermal expansion and less thickness compared with the first metal layers (11), the first metal layers (11) and second metal layers (12) being alternately stacked, the first metal layers uppermost and lowermost layers of the layers, a thickness of at least one internally-arranged first metal layer (11a) being thicker than that of the lowermost and uppermost layers. Accordingly, heat generated from the electronic component (5) can be dissipated well to the outside, and a coefficient of thermal expansion of a mounting portion (1a) can be brought close to that of the electronic component (5) or the like.

A bond wire circuit includes bond wires arranged relatively to provide a selected inductance. In connection with various example embodiments, respective bond wire loops including forward and return current paths are arranged orthogonally. Each loop includes a forward bond wire connecting an input terminal with an intermediate terminal, and a return bond wire connecting the intermediate terminal to an output terminal. The return bond wires generally mitigate return current flow from the intermediate terminal in an underlying substrate. In some implementations, the loops are arranged such that current flowing in each of the respective loops generates equal and self-cancelling current in the other of the respective loops.

The present invention aims to provide a surface protection tape for use in a dicing step, which protects a surface of a material to be cut from staining owing to attachment of dust and the like such as shavings by sticking the surface protection tape on the surface of the material to be cut in the dicing step and cutting the tape together with the material to be cut, and which is easily peeled and removed from individual chips after the dicing step. There is provided a surface protection tape for dicing to be stuck on a surface of a material to be cut and to be cut together with the material to be cut, which includes a contractible film layer that contracts in at least one axis direction by a stimulus and laminated thereon a restriction layer that restricts the contraction of the contractible film layer, and which is peeled off with undergoing spontaneous rolling from one end part in one direction or from opposing two end parts toward a center to form one or two cylindrical rolls when the stimulus that causes the contraction is applied.

An integrated circuit (IC) package includes an interface die and a separate storage die. The interface die has a synchronous interface to receive memory access commands from an external memory controller, and has a plurality of clockless memory control interfaces to output row and column control signals that correspond to the memory access commands. The storage die has a plurality of independently accessible storage arrays and corresponding access-control interfaces to receive the row and column control signals from the clockless memory control interfaces, each of the access-control interfaces including data output circuitry to output read data corresponding to a given one of the memory access commands in a time-multiplexed transmission.
