A semiconductor substrate (SUB) has a recessed portion (CP1) and a recessed portion (CP2) in a main surface. An n + source region (SR) and an n + drain region (DR) sandwich the recessed portion (CP1) and the recessed portion (CP2) in the main surface. A p - epitaxial region (EP) and a p-type well region (WL) serving as a channel formation region are formed in the main surface between the n + source region (SR) and the recessed portion (CP1). A gate electrode layer (GE) is formed on the channel region with a gate insulation film (GI) interposed therebetween, and extends onto an element isolation insulation film (SI) in the recessed portion (CP1). The recessed portion (CP1) and the recessed portion (CP2) are arranged to be adjacent to each other to sandwich a substrate protruding portion (CV) protruding toward the main surface side with respect to a bottom portion of each of the recessed portion (CP1) and the recessed portion (CP2).

A method comprisesproviding a monocrystalline silicon wafer (11) having a principal surface (17) which supports a masking layer (24), for example silicon dioxide or polycrystalline silicon, having windows (25) to expose corresponding regions of the silicon wafer, forming silicon carbide seed regions (30) on the exposed regions of the wafer, for example by forming carbon and converting the carbon into silicon carbide, and growing monocrystalline silicon carbide (31) on the silicon carbide seed regions. Thus, monocrystalline silicon carbide can be formed selectively on the silicon wafer which can help to avoid wafer bow.
