Transistor having a heterojunction and manufacturing method thereof |
摘要 |
A transistor includes a semiconductor substrate comprising a first region and a second region. The transistor further includes an emitter and a base disposed on the first region, and a collector disposed on the second region. The emitter includes a heterojunction. The heterojunction is at a same height as a junction between two different insulating materials that separate the emitter and the base. |

1. A transistor comprising:
a semiconductor substrate comprising a first region and a second region; an emitter and a base disposed on the first region; and a collector disposed on the second region, wherein the emitter is disposed on an upper surface of the semiconductor substrate forming a heterojunction between the emitter and the upper surface of the semiconductor substrate, wherein the emitter and the base are spaced apart by a stacked layer including at least two different insulating materials, and wherein a junction between the at least two different insulating materials of the stacked layer has a substantially same height as a height of the heterojunction between the emitter and the upper surface of the semiconductor substrate. |
