Filed: 1992-04-23
Abstract: PURPOSE:To prevent the undesired diffusion of a p-type impurity and to obtain a high current gain and an excellent high-frequency characteristic by manufacturing a compound semiconductor device wherein a laminated region is used as a base layer and an n-type emitter layer is formed adjacently to one side of the base layer and an n-type collector layer is formed adjacently to the other side of the base layer. CONSTITUTION:On a base layer 5, an emitter layer is formed which is constituted of a first layer 6-1, a second layer 6-2, and a third layer 6-3 and whose composition increases from 0.1 to 0.3 as it gets away from the base layer 5, slowly decreasing to zero again, and which is brought into contact with an n<+>-type GaAs emitter cap layer 7. Because of this, the energy band structure from the base layer 5 through the emitter cap layer 7 is continuous and therefore the movement of the carrier can be made smooth by eliminating a notch or a spike. Consequently, a hetero-junction bipolar transistor of a high current gain and an excellent high-frequency characteristic can be obtained.
