Abstract
An integrated circuit device has a plurality of active devices which are formed on a semiconductor body. A plurality of narrow isolating regions of insulating material are vertically formed on the semiconductor body such that at least one of the narrow isolating regions separates and thereby isolates adjacent active devices. Essentially all of said isolating regions are substantially equal in width, preferably less than or equal to about 0.5 .mu.m.
