  • Patent number: 11609133
    Abstract: An object is to reduce the influence of noise due to electric conduction carriers trapped between the surface of a silicon substrate and an oxide and thus achieve strain detection with a high S/N ratio. This semiconductor strain detection element includes: a silicon substrate; and a first impurity diffusion layer having a conduction type different from the silicon substrate, the first impurity diffusion layer being formed inside under a surface of the silicon substrate, wherein an amount of strain in the silicon substrate is detected on the basis of change in a resistance of the first impurity diffusion layer.
