A semiconductor device includes a substrate, a SiC drift layer formed above the substrate, a GaN-based semiconductor layer that is formed on the SiC drift layer and includes a channel layer, a source electrode and a gate electrode formed on the GaN-based semiconductor layer, current blocking regions formed in portions of the SiC drift layer and located below the source and gate electrodes, and a drain electrode formed on a surface that opposes the GaN-based semiconductor layer across the SiC layer.
