ABSTRACT:
A semiconductor devive comprises;
a collector region of first conductivity type;
a base region of second conductivity type;
an emitter region of the first conductivity type;
a thin film provided on the emitter region and capable of flowing therein a tunnel current; and
a polycrystalline layer laminated on the thin film.
An energy .DELTA..phi..sub.B of potential barrier formed at a grain boundary is not less than a heat energy kT at a temperature therein.
