Abstract

A vertical reactor for chemical vapor deposition having an H.sub.1 /D.sub.1 ratio in the range of 1.10 to 1.40, where H.sub.1 is the height of the reactor bell jar enclosure above the susceptor and D.sub.1 is the diameter of the susceptor. Reactor performance is further improved by extending the outermost coil of the induction coil heating the susceptor beyond the outer diameter of the susceptor and by extending the innermost coil of the induction coil within the inner diameter of the susceptor.
