Abstract
PURPOSE: To minimize the gate serial resistance to enhance the area denisity and at the same time to obtain the necessary transmission conductance in order to realize reduction of the noise, by providing the poly-crystal Si layer connecting to the J- FET on the surface gate of the J-FET and then adding the electrode wiring on the Si layer.
CONSTITUTION: N-type layer 21 is epitaxial-grown on P-type Si substrate 20, and the P-type diffusion region reaching substrate 20 is formed into an island shape with formation of the electrode diffusion layers of P-type source regions 22 and drain region 23 each. Then P--type channel region 24 is formed by the ion implantation, and at the same time N-type region 27 for contact electrode use is formed by diffusion at the bottom part gate of epitaxial layer 21. After this, SiO2 film 24 is coated over the entire surface with the window drilled at the formation area of the surface gate, and then the poly-crystal Si layer containing the N-type impurity is stacked over the entire surface to be then removed except at the surface gate diffusion part. Using the Si layer as the diffusion source, surface gate region 25 is formed, and Al electrodes 31∼33 are attached to the source, the drain and the bottom part gate respectively.
