Disclosed is a transistor having a first region of a first conductivity type for injecting charge carriers into the transistor and a laterally extended second region of the first conductivity type having a portion including a contact terminal for draining said charge carriers from the transistor, wherein the first region is separated from the second region by an intermediate region of a second conductivity type defining a first p-n junction with the first region and a second p-n junction with the second region, wherein the laterally extended region separates the portion from the second p-n junction, and wherein the transistor further comprises a substrate having a doped region of the second conductivity type, said doped region being in contact with and extending along the laterally extended second region and a further contact terminal connected to the doped region for draining minority charge carriers from the laterally extended second region. An amplifier circuit and IC including such transistors are also disclosed.

Transistor amplifier circuit and integrated circuit

The disclosure relates to bipolar transistor devices and a method of fabricating the same. The device comprises a field plate, in an isolation region adjacent to a base-collector junction of said active region. The isolation region comprises a gate terminal arranged to be biased independently of a collector, base or emitter terminal of said transistor.

Bipolar transistor device and method of fabrication

A semiconductor device comprising a bipolar transistor and a method of making the same. A power amplifier including a bipolar transistor. The bipolar transistor includes a collector including a laterally extending drift region. The also includes a base located above the collector. The bipolar transistor further includes an emitter located above the base. The bipolar transistor also includes a doped region having a conductivity type that is different to that of the collector.
