Abstract: PURPOSE: A semiconductor device and its manufacturing method are provided to contain a variable capacitance element having a large capacitance changing range. CONSTITUTION: A depletion layer extends in a greater region, i.e., from a position near the surface of the silicon substrate to the lower end of the N layer. Therefore, in the variable capacitor, the depletion layer can extend across the whole depth of the N layer. As a result, the capacitance of the variable capacitor has a greater variation range than that of the case where the PN junction is present within the silicon substrate. In particular, the capacitance of the variable capacitor has a greater variation range as the range of the depletion layer is increased, making it possible to deal with a higher frequency.
