Abstract: According to the present disclosure, a strain gauge includes: a flexible substrate; a resistor made from a film containing Cr, CrN, and Cr2N, on one surface of the substrate; an insulating layer covering the resistor; and a conductive barrier layer covering the insulating layer.

Abstract: A method of manufacturing a semiconductor device includes forming a photoresist defining an opening on an upper surface of a semiconductor wafer; and forming an electrode in the opening using a plating technique, in which the step of forming the electrode includes forming a first plated layer at a first current density such that the first plated layer has a first thickness, and forming a second plated layer on an upper surface of the first plated layer at a second current density higher than the first current density such that the second plated layer has a second thickness greater than the first thickness.
