摘要:
A non-volatile memory cell having a structure having improved integration and simplified electrode wiring structure. The programmable non-volatile memory cell of the present invention adopts a mono-layer gate scheme to simplify the electrode wiring structure and to eliminate a current leakage problem of an insulating film between electrodes. A side and bottom of a semiconductor region, which is disposed directly below a capacity electrode section with a gate insulating film interposed therebetween that compose a control electrode, are isolated from another semiconductor region and semiconductor substrate by insulating films. Thus, a high programming control voltage which is not limited by a junction yield voltage between the semiconductor regions and semiconductor substrate may be applied. Due to that, an area of the capacity electrode section of a floating electrode may be considerably reduced.

A semiconductor device has a thin-film resistor trimmed by laser. The semiconductor device comprises a semiconductor substrate having an element region that covers at least part of the surface of the semiconductor substrate, a first insulation film disposed on the surface of the semiconductor substrate, and a second insulation film disposed on the surface of the semiconductor substrate through an opening of the first insulation film. The opening is formed by selectively removing at least part of the first insulation film at a location on the surface of the semiconductor substrate where the element region is not involved. The thin-film resistor is formed on the second insulation film.

A metal laminated substrate for an oxide superconducting wire is produced by removing, in a state where a copper foil to which rolling is applied at a draft of 90% or more is held at a temperature below a recrystallization temperature, an absorbed material on a surface of the copper foil by applying sputter etching to the surface of the copper foil; removing an absorbed material on a surface of a nonmagnetic metal sheet by applying sputter etching to the surface of the nonmagnetic metal sheet; bonding the copper foil and the metal sheet to each other by reduction rolls at an applied pressure of 300 MPa to 1500 MPa; orienting crystals of the copper by heating a laminated body obtained by bonding at a crystal orientation temperature of copper or above; and forming a protective layer on a copper-side surface of the laminated body by coating.

A semiconductor pressure sensing apparatus includes a metallic stem having a diaphragm and a semiconductor sensor bonded to the diaphragm. The semiconductor sensor includes a gauge section and first and second bonding pads. The gauge section is configured to be deformed according to a deformation of the diaphragm. The first and second bonding pads are respectively connected to different positions of the gauge section so that an electrical resistance between the first and second bonding pads can change with a change in the deformation of the diaphragm. The gauge section is formed to a semiconductor layer of an silicon-on-insulator substrate. The semiconductor sensor is directly bonded to the diaphragm by activating contact surfaces between the semiconductor sensor and the diaphragm.
摘要:
A method for manufacturing a semiconductor device having on a silicon substrate semiconductor elements and aluminum (Al) alloy wiring leads as electrically connected thereto is disclosed. The method includes the steps of forming on the silicon substrate an Al alloy layer containing therein copper (Cu), and forming on the Al alloy layer a titanium nitride (TiN) film with enhanced chemical reactivity by using sputtering techniques while applying thereto a DC power of 5.5 W/cm2 or less. Fabrication of such reactivity-rich TiN film on the Al alloy layer results in a reaction layer of Al and Ti being subdivided into several spaced-apart segments. In this case, the reaction layer hardly serves as any diffusion path; thus, it becomes possible to prevent Cu as contained in the Al alloy layer from attempting to outdiffuse with the reaction layer being as its diffusion path. This makes it possible to suppress or minimize unwanted fabrication of AlN on or above the surface of an Al containing lead pattern, thereby enabling increase in electromigration (EM) lifetime of electrical interconnect leads used.

摘要:
The object of the present invention is to provide a closed battery capable of rapidly releasing the internal pressure thereof and at the same time disconnecting the current to effectively prevent itself from temperature rising and exploding so that in such a completely closed battery it may assure the safety and reliability thereof, when the internal pressure is elevated due to short circuit, overcharge, reverse charge, or the like. A valve element 5 is provided with a slit 3 between the circumference thereof and a metal substrate 1. When the internal pressure of a battery is elevated, the valve element 5 is smoothly raised up together with a metal foil 2 from a bending fulcrum portion 4 to thereby cut a lead wire 6 or permit a braze portion 8 to detach from the lead wire 6, thus disconnecting the current reliably. Then, the metal foil which usually closes the slit formed around the circumference of the valve element 5 is allowed to burst stably and accurately at a prescribed pressure to thereby form a valve opening portion 7 so that the internal gas of the battery can be discharged.
