Title: Junction type field-effect transistor
Inventor: INOUE TAKU
IPC: H01L29/808
Filed: 1990-10-23
Abstract: PURPOSE:To maintain drain current in a saturated region independent of drain voltage by forming an epitaxial layer having a lower resistivity on the source side than on the drain side to prevent the pinch-off point of a depletion layer from moving toward the source. CONSTITUTION:An n-type epitaxial layer 7 is formed on a p-type semiconductor substrate 1, and a p-type guard ring 2 is formed in the layer. An n-type impurity is introduced to the source region to form n<+> diffused layer 6, and then p<+> diffused gate layer 4 is formed. An n-type impurity is introduced to form a source 3 in the n<+> diffused layer 6 and a drain 5 in the epitaxial layer 7. As a result, the depletion layer around the diffused gate layer 4 has a different width on the source side from that on the drain side, so that the formation of a depletion layer by drain voltage is limited. This prevents the movement of the pinch-off point of the depletion layer toward the source, thereby preventing the increase in drain current with drain voltage.
