Abstract
PURPOSE: To obtain a J-FET which features a high density and the mutual conductance with low noise and can be unified suitably with the bipolar IC, by forming the source region within the gate region and then forming the channel region of a wider width than the source region within these regions and in parallel to the substrate.
CONSTITUTION: N--type layer 2 to become the drain region is epitaxial-grown on P-type Si substrate 1 to be covered with oxide film 7, and P-type gate region 3 is formed through diffusion whithin layer 2 with the opening drilled. Film 7 is then renewed, and the opening is drille dagain to form N+-type source region 4 through diffusion within region 3. At the same time, N+-type region 5 for draw-out of the drain electrode is formed too within layer 2. After this, film 7 is coated again. Then an opening wider than region 3 is drilled to inject the N-type impurity ion, and thus N-type channle region 6 featuring a wider width than region 3 and 4 is formed within region 3 and 4 through a heat treatment. After this, drain electrode 8 and source electrode 9 are attached to region 5 and 4 respectively.
