Abstract
A transversal bipolar transistor is structured to have a single crystal semiconductor film provided on a single crystal semiconductor region which is provided on a semiconductor substrate. The semiconductor substrate is of a first conductivity type, and the single crystal semiconductor region is of a second conductivity type which is opposite to the first conductivity type. The single crystal semiconductor film is divided in the transversal direction into a central portion of the second conductivity type for a base region and left and right portions of the first conductivity type for emitter and collector regions. The transversal bipolar transistor may be integrated with a vertical bipolar transistor commonly on the semiconductor substrate.
