Abstract: PURPOSE:To improve a frequency characteristic by a method wherein a contact layer composed of a compound semiconductor whose forbidden band width is narrower than that of a compound semiconductor forming an active layer is formed on a source region and a drain region which have been formed on the active layer composed of the compound semiconductor. CONSTITUTION:An active layer 4 composed of n-type GaAs, a gate electrode 5 formed in a prescribed position of the active layer 4 as well as a source region 7 and a drain region 8 which have been formed on the surface layer 4 so as to sandwich the gate electrode 5 are formed on one main face of a semiinsulating GaAs substrate 1; an FET transistor is formed. By this constitution, a contact layer 10, composed of In0.2Ga0.8As, whose forbidden band width is narrower than that of GaAs is formed on the source region 7 and the drain region 8.
