Abstract

PURPOSE:To enable the function of a comparator, for example, using only a hot electron transistor by a method wherein, out of two emitter-base layers for common use, either one is used as the emitter and the other one is operated as the base. CONSTITUTION:Emitter-base commonly used layers (for example, n-type GaAs emitter-base layers 4 and 6 for common use) are opposingly formed in such a manner that a tunnel-barrier layer (for example, AlGaAs tunnel-barrier layer 5) is pinched. A collector layer (for example, n-type GaAs layers 2 and 8) are opposingly formed in such a manner that said emitter-base commonly used layers, with which the tunnel-barrier layer is pinched, are pinched through the intermediary of a collector-barrier layer (for example, Al0.3Ga0.7As collector- barrier layers 3 and 7). As a result, the comparator wherein three transistors were required before, for example, can be constituted with only one transistor.

[Detailed Description of the Invention] [Summary] The present invention provides a tunnel barrier in a hot electron transistor, which is a type of high-speed semiconductor device in which thin semiconductor layers are laminated to allow current to flow in the vertical direction. Emitter/base common layers are formed to face each other so as to sandwich the layers, and collector layers are formed to face each other so as to sandwich the emitter/base common layers sandwiching the tunnel/barrier layer via a collector/barrier layer. In particular, a single hot electron transistor can function as a comparator, for example.
