Abstract
A semiconductor device includes: a silicon substrate; and a silicon oxide film disposed on the silicon substrate. The silicon oxide film includes a part, which separates from a surface of the silicon substrate, so that the silicon oxide film provides a three-dimensional construction. By using the three-dimensional construction, an additional function such as a resistor or a capacitor is easily added in the device. Further, a manufacturing method of this three-dimensional construction is simple and has a low cost.
