Abstract
PURPOSE: To increase relative conductance without decreasing counter withstanding voltages, threshold voltages, and the like by forming the gate regions of J-FETs having many channels in a hollow hexagonal-column shape, and by using a same chip size.
CONSTITUTION: An N-type layer 2 is epitaxially grown on a P-type Si substrate 1, and a P+ gate region 3 reaching the substrate 1 is diffused on both ends of the layer 2. Then, a plurality of P+ regions 4 which do not reach the substrate 1 are provided in the layer 2 which is surrounded by the region 3, and all the surface is covered by an oxidized film 7. Openings are made on both sides of the regions 4, and N+ source regions 5 and drain regions 6 are diffused. In this constitution, the shape of the P+ gate region 4 is formed as a hollow hexagonal column. Said source regions 5 and drain regions 6 are located in the hollow portions constituted by the regions 4. In this method, the area of the channel region is increased 2.5 times that of the ordinary case, and the effective gate width is also increased 2.5 times, thereby relative conductance is increased.
