Abstract:
A floating region includes a high-concentration region and a low-concentration region that are arranged along a thickness direction of a silicon carbide substrate. A concentration of a p-type dopant in the low-concentration region is lower than a concentration of the p-type dopant in the high-concentration region. The high-concentration region contacts the low-concentration region, and is disposed between a bottom surface of a trench and the low-concentration region. In graph obtained by plotting the concentration of the p-type dopant in the floating region along the thickness direction, a bending point or an inflection point appears on a boundary between the high-concentration region and the low-concentration region. A content of the p-type dopant in the low-concentration region is equal to or higher than a content of an n-type dopant in a portion of the drift region, which is adjacent to the low-concentration region in the thickness direction.

Claim (Index 2):
The metal-oxide-semiconductor field-effect transistor according to  claim 1 , wherein,\n where NA represents the maximum concentration of the p-type dopant in the high-concentration region and NB represents the maximum concentration of the p-type dopant in the low-concentration region, a condition of NA/NB\u22652.5 is satisfied.
