<p>A semiconductor device (10) comprises a substrate (11), a semiconductor layer (12), an insulation film (13), a protective film (15), a source electrode (21), a drain electrode (22), a gate electrode (23). The semiconductor device (10) comprises a protective film (15) formed so as to cover at least an upper surface of the insulation film (13). This enables preventing aluminum contained in the source electrode (21) and the drain electrode (22) from reacting with material contained in the insulation film (13). Accordingly, the increase of the resistance of the electrode and the increase of current collapse are prevented. Accordingly, the semiconductor device (10) has a satisfactory electric performance characteristics.</p> |
