Title: Conductivity modulation type vertical mosfet
Inventor: SEKI YASUKAZU
IPC: H01L29/68
Filed: 1986-12-15
Abstract: PURPOSE:To suppress a latchup by digging a source region in a V-shaped section, and escaping the holes of a highest hole concentration region through a hole drawing layer from a hole drawing hole, thereby reducing the number of holes flowing through a P-type base layer under a channel region. CONSTITUTION:A P<+> type hole drawing layer 17 is formed directly under a hole drawing hole 16 at a region except a channel and a source 1 on the main surface of an N<-> type base layer 4. Holes implanted from a drain layer 7 in which a source region is so dug as to become a V-shaped section can be removed through the layer 17. Particularly, the holes are electrostatically attracted to electrons of high density flowing to the layer 4 through a gate to operate to escape the holes of a highest hole concentration region. Thus, the number of the holes which pass a short-circuit resistor Rp is reduced, and since an N-P-N transistor 13 is scarcely operated without raising the base potential of the transistor 13, a latchup can be suppressed.
