A ZnSe based light emitting device enabling longer lifetime is provided. The light emitting device is formed on a compound semiconductor, includes an active layer positioned between an n-type ZnMgSSe cladding layer and a p-type ZnMgSSe cladding layer, and has a barrier layer having a band gap larger than that of the p-type ZnMgSSe cladding layer, provided between the active layer and the p-type ZnMgSSe cladding layer.

In the method for fabricating a semiconductor device of the present invention, a collector layer of a first conductivity type is formed in a region of a semiconductor substrate sandwiched by device isolation. A collector opening is formed through a first insulating layer deposited on the semiconductor substrate so that the range of the collector opening covers the collector layer and part of the device isolation. A semiconductor layer of a second conductivity type as an external base is formed on a portion of the semiconductor substrate located inside the collector opening, while junction leak prevention layers of the same conductivity type as the external base are formed in the semiconductor substrate. Thus, the active region is narrower than the collector opening reducing the transistor area, while minimizing junction leak.

An injected current restriction region for restricting an increase in defects by restricting an injected current for light emission is provided inside a ZnSe-based LED. When an end of a light transmitting Au electrode is separated from a cleavage plane, a region near the cleavage plane serves as the injected current restriction region.
