Abstract: In a compound semiconductor device constituting a field effect transistor having a buried p region 3, a channel region 4 is formed thin and highly doped by n-type impurity, and the buried p region 3 is formed shallowly and highly doped by p-type impurity to compensate the highly doped channel region 4. In order to prevent a leakage current between the highly doped buried p region 3 and a gate electrode 5, a low concentration p-type impurity region 2 is formed on both sides of the highly doped buried p region 3 to thus prevent a current flow via a portion other than a channel region. Accordingly, there can be provided the compound semiconductor device including an FET which is able to suppress both the deterioration in the pinch-off characteristic and the leakage current between neighboring elements due to p-type impurity conduction other than a channel in an FET which has a high concentration and thin active layer, while suppressing the short channel effect.
