Abstract:
In a bipolar transistor, a collector layer includes three semiconductor layers: an n-type GaAs layer (Si concentration: about 5×10 15  cm −3 , thickness: about 350 nm), a p-type GaAs layer (C concentration: about 4.5×10 15  cm −3 , thickness: about 100 nm, sheet concentration: 4.5×10 10  cm −2 ), and an n-type GaAs layer Si concentration: about 5×10 15  cm −3 , thickness: about 500 nm. The sheet concentration of the p-type GaAs layer is set to less than 1×10 11  cm −2 .

Claim (Index 3):
The semiconductor device according to  claim 1 , wherein\n the first-conductivity-type semiconductor layers include a second high-concentration layer having an impurity concentration more than the impurity concentration of the impurity concentration layer, and the second high-concentration layer is disposed in contact with the base layer or between the base layer and the impurity concentration layer.
