A multi-layered circuit substrate for a semiconductor device comprises a multi-layered circuit substrate body having first and second surfaces and comprising a plurality of conductive pattern layers integrally laminated one on the other from the first surface to the second surface, so that a plurality of semiconductor device elements can be arranged on the first surface of the substrate body; and a plate member, a rigidity thereof being higher than that of the substrate body, attached to the second surface of the substrate body. A plurality of semiconductor elements can be mounted on the semiconductor element mounting surface defined on the first surface of the substrate body.
摘要:
A centrifugally cast double-layer tube with resistance to carbon deposition, comprising an inner layer of a specific metallic material containing 1-10 wt % of Al and an outer layer of a heat resisting metallic material, can be applied to apparatuses for treating a fluid, containing hydrocarbons, their derivatives, or carbon monoxide, at elevated temperatures and to piping for transferring the fluid without carbon deposition on its inside surface, because the surface of said inner layer is oxidized to form a firm Al-containing oxide film prior to and/or during the treatment of the fluid, and also a sufficient strength and ductility of the tube are preserved by the support of the outer layer of said tube.

A multilayer wiring substrate for providing a capacitor structure inside a multilayer wiring structure is disclosed. The multilayer wiring substrate includes a dielectric layer including a resin material mixed with an inorganic filler, wherein the inorganic filler is fabricated by mixing a paraelectric filler with an inorganic filler having a high dielectric constant.
摘要:
A multilayer circuit board for mounting a semiconductor element thereon, comprising a core substrate of a metal material and a plurality of wiring layers stacked on either side of the core substrate, each of the stacked wiring layers being isolated from an adjacent wiring layer by an insulating layer interposed therebetween, the multilayer circuit board having an area at which a heat spreader for dissipating heat generated from the semiconductor element mounted on the circuit board is to be joined to the multilayer circuit board, wherein the multilayer circuit board allows the heat spreader to be joined to the core substrate without the insulating layers being interposed therebetween. A semiconductor device using the multilayer circuit board is also disclosed.
摘要:
A resin plate having wiring pattern recesses and via through holes is made. All of the surfaces of the resin plate including inner walls of the wiring pattern recesses and via through holes are coated with a metal film. An electro-plating is applied using the metal film as a power-supply layer to fill a plated metal into the wiring pattern recesses and via through holes. The metal film formed on the resin plate except for the inner walls of the wiring pattern recesses and via through holes is removed, so that wiring pattern and via are exposed on a surface the same as that of the resin plate.
