Abstract: A substrate evaluation chip is used to perform a test for evaluating a thermal characteristic of a mounting substrate that is mountable a power semiconductor. The substrate evaluation chip includes an insulating substrate bonded with the mounting substrate, and a heating pattern that is formed on a surface of the insulating substrate by a metallic film and is arranged by having a predetermined shape that is optimized to beat the insulating substrate more uniformly. The insulating substrate is a substrate in which an insulating film is formed on a surface of a single crystal substrate having a thermal conductivity of 250 [W/mK] or more.

Abstract: A bonding material (10) of the present invention includes an amorphous silver film (12).

Abstract: A bonding device (100) bonds at least one component (C) to a substrate (B) using a metal material (M). The bonding device (100) includes a wall section (20), at least one pressing section (40), and a rotational shaft (30). The rotational shaft (30) is fixed to the wall section (20). Each pressing section (40) has an arm (42) and a presser (43) or a substrate supporting member (90). The arm (42) extends from the rotational shaft (30). The arm (42) pivots about the rotational shaft (30). The presser (43) presses the component (C). The substrate supporting member (90) is disposed on a reference surface (142). The substrate supporting member (90) supports the substrate (B). The component (C) is bonded to the substrate (B) through point contact of the presser (43) with the component (C) or point contact of the substrate supporting member (90) with the reference surface (142).

Abstract: Provided is an electrode like a protruding electrode that is self-standing on a substrate. A conductive paste (202) contains a conductive powder, an alcoholic liquid component, and no adhesives. The conductive powder contains conductive particles having a thickness of 0.05 ?m or more and 0.1 ?m or less and a representative length of 5 ?m or more and 10 ?m or less, the representative length being a maximum diameter in a plane perpendicular to the direction of the thickness. The weight percentage of the alcoholic liquid component relative to the conductive paste is 8% or more and 20% or less.
