Method of fabrication of dielectrically isolated CMOS device with an isolated slot.

摘要

A method of fabricating an integrated circuit on a body of semiconductor material having a major surface layer of (110) crystallographic orientation by etching vertical slots into the layer to form distinct islands; depositing dopant species in predetermined ones of the silicon islands so that the major surface and exposed edges of ones of the islands become second conductivity type; and thermally oxidizing the exposed surface portions of the body so that oxide fills the vertical slots between the islands.
