A shallow trench isolation type semiconductor device includes a gate insulating layer formed in a first region and in a second region. The gate insulating layer is of greater thickness in the first region, relative to the thickness of the gate insulating layer in the second region. A shallow trench isolation layer is also formed in the first region and the second region, the shallow trench isolation layer in the first region being thinner than shallow trench isolation layer in the second region.
