Abstract
The inventive multilayer semiconductor integrated circuit has a columnar semiconductor region provided between adjacent two layers and a control electrode provided in the vicinity of the columnar semiconductor region. The transference of a signal between the adjacent two layers is carried out through the columnar semiconductor region the electric conductivity of which is controlled by a control signal applied to the control electrode. That is, the area corresponding to the columnar semiconductor region functions as an active element.
