METHOD FOR DIFFUSION JOINING AND DEVICE THEREFOR WITH PRESSURE VARIATION
A method for diffusion joining by way of a first and a second stamp, wherein plate-like joining parts are arranged between the two stamps. A pressure is applied to the joining parts by way of the first and/or the second stamp for the purpose of diffusion joining. In addition, a variation of the pressure is also introduced. The pressure and the pressure variation are applied via the first stamp, whereas the second stamp can be rigid. Further disclosed is a device for carrying out the method.
METAL JOINT, METAL JOINT PRODUCTION METHOD, SEMICONDUCTOR DEVICE, AND WAVE GUIDE PATH
Provided is a metal joint (5) including: a Ag—Cu—Zn layer (7); and Cu—Zn layers (6) joined to both surfaces of the Ag—Cu—Zn layer (7), wherein the Ag—Cu—Zn layer (7) has a composition in which a Cu component is 1 atm % or more and 10 atm % or less, a Zn component is 1 atm % or more and 40 atm % or less, and the balance is a Ag component with respect to the total 100 atm %, and wherein the Cu—Zn layers (6) have a composition in which a Zn component is 10 atm % or more and 40 atm % or less and the balance is a Cu component with respect to the total 100 atm %. It is therefore possible to obtain the metal joint (5), which is capable of joining metal base materials to each other without being limited to aluminum-based materials, and also have high mechanical strength.

METHOD OF MANUFACTURING ALL-SOLID-STATE BATTERY WITH STABLE INTERFACE OF LITHIUM ANODE
A method of manufacturing an all-solid-state battery includes preparing a solid electrolyte layer, providing lithium metal to the solid electrolyte layer to prepare a stack, and radiating ultrasonic waves or sound waves to the stack. The method provides an all-solid-state battery with a stable interface between an anode formed of lithium metal and a solid electrolyte layer.
WELDING APPARATUS AND METHOD OF MANUFACTURING WELDED BODY
Provided are a welding apparatus having a reduced size. A welding apparatus includes a support base having a placement surface, and a restriction member. A substrate with a semiconductor element disposed thereon is placed on the placement surface such that a surface electrode of the semiconductor element faces upward. A wiring member is placed on the surface electrode. The restriction member restricts movement of the surface electrode and the wiring member in the directions away from each other, by holding the substrate with the semiconductor element disposed thereon and the wiring member, between the placement surface and the restriction member. The welding apparatus further includes a laser device. The laser device locally heats a welding interface between the surface electrode and the wiring member by irradiating a laser beam onto the surface of the wiring member through a hole in the restriction member.
