Title: Manufacture of junction type field effect transistor
Inventor: KISHIMOTO MITSUO
IPC: H01L21/265
Filed: 1978-01-18
Abstract: PURPOSE: To reduce the variance of a saturation drain current inside of a Si substrate by forming a well of low density through ion injection.  
     CONSTITUTION: An opening is made in p-typt Si 1 of 2 to 4Ωcm covered with SiO 2  10 and phosphorous ions are injected under conditions of 80keV, 8 degrees-off, and 3×10 12  to 16×10 12 cm -3 ; diffusion is done at approximate 1200°C for five hours  after annealing in dry N 2  below 950°C, thereby forming n-type well 11. Next, p + - type layer 4 and channel stopping layers 12 in substrate 1 are formed, and n + -type connection layers 5 and 6 are made before main parts of the JFET are formed. In this way, since the density of drain-source formation region 11 is uniform and low through ion injection and an adequate quantity of ions are injected into the region 11, the variance in saturation drain current lessens and gm can be made large, so that the yield will improve.
