Abstract
A vertical MOS-FET device having a planar multicell structure which is constituted by an assembly of elementary cells of a polygonal form having a source zone, a shortcircuit region, a channel zone and a drain zone. In the space between adjoining apices of a number of elementary cells there are provided complementary elements having a construction similar to that of the previously-mentioned cells but having a polygonal form adapted to the configuration of the cells. Thus, the overall length of the channel zones per unit surface area can be optimized.
