Abstract
PURPOSE:To improve the improper withstand voltage of a junction type field effect semiconductor device by forming gate diffused windows of source and drain of one mask and thereby improving the diffusing mask matching accuracy in a process of manufacturing the transistor. CONSTITUTION:An n type epitaxial layer 2 is grown on a P type silicon substrate 1 of a wafer, a surface thermal oxide film (SiO2 film) 3 is formed on the wafer, and source and drain diffusing windows 4 and gate diffusing window 7 are simultaneously formed by an etching treatment with one photomask. Subsequently, the gate diffusing window 7 is shielded with a CVD.SiO2 film 9. Phosphorus (or arsenid) is deposited (or ion implated) or diffused through the source and drain diffusing windows, and n<+> type source and drain 5, 6 are formed. Further, a CVD.SiO2film 9 is removed with etchant, boron is diffused through the gate diffusing window 7, and a p<+> type gate 8 is thus formed.
