摘要： A semiconductor strain sensor having a strain sensor chip composed of a semiconductor substrate having a piezoresistive element as a strain detection section. The semiconductor strain sensor has a stable characteristic for a long period of time and a stable conversion factor of a strain generated in the strain sensor chip corresponding to a strain of an object to be measured, within a strain range of a size to be measured. The strain sensor chip is bonded to a metal base plate with a metal bonding material. The metal base plate has two or four extending members, which protrude from a side of the strain sensor chip for attaching the strain senor chip to the object to be measured. Preferably, a groove is arranged between a metal base plate undersurface area, which corresponds to the bonding area where the strain sensor chip is bonded to the metal base plate, and the undersurfaces of the extending members, and a protruding section sandwiched by the grooves is arranged on the undersurface of the metal base plate.

摘要： PROBLEM TO BE SOLVED: To prevent a semiconductor element or a wafer from warping or the interface layer with a layer insulation film, etc., from peeling due to thermal stresses of a re-wired layer in a semiconductor device of a small size nearly the size of the semiconductor element. SOLUTION: The re-wired layer uses as a main material a Cu composite alloy containing Cu2O having smaller linear expansion coefficient and a smaller modulus of elasticity than those of Cu simple substance at a ratio of 80 vol.% or less, thereby lowering the thermal stress of the re-wired layer. Thus, a semiconductor device can be realized wherein a semiconductor element or wafer hardly warps and peeling between layers hardly occurs.
