Title: Buried gate type gto thyristor
Inventor: HAYASHI YASUHIDE
IPC: H01L29/10
Filed: 1984-04-26
Abstract: PURPOSE:To eliminate the dispersion of characteristics in elements and among the elements by directing the whole channels in the elements in the same direction and conforming the longitudinal directions of the channels to the direction of a pattern shift on epitaxial growth. CONSTITUTION:A P2<+> layer is formed to a pattern in which a latticed channel CH is divided and shaped extending over the whole surface in a region at a central section except the peripheral section of a wafer W. The longitudinal directions of each channel CH are aligned so as to be mutually arranged in parallel, and constituted so as to run parallel with an orientation flat CF in the wafer W. The flat CF and the direction of a pattern shift generated on epitaxial growth shown in the arrow PS coincide in the wafer W. Consequently, angles formed by the longitudinal directions of the channels CH and the direction PS are aligned. The dispersion of characteristics in elements and among the elements can be eliminated with regard to crystal defects to be generated when the sheet resistance of the P2<+> layer is reduced in order to improve turn-OFF characteristics in a GTO thyristor having such a buried gate pattern.
