    摘要: A semiconductor device includes: a semiconductor substrate including a first semiconductor layer on the semiconductor substrate; multiple semiconductor elements in the semiconductor substrate; and an ineffective region. Each semiconductor element includes: a second semiconductor layer in a surface portion of the first semiconductor layer; a third semiconductor layer disposed in another surface portion of the first semiconductor layer and spaced a part from the second semiconductor layer; and a control layer disposed on a portion of the first semiconductor layer between the second semiconductor layer and the third semiconductor layer. The ineffective region is disposed in the semiconductor substrate between at least two adjacent semiconductor elements; and does not provide a function of the semiconductor elements.
