Abstract: PURPOSE:To make it possible to form a film without having the surface of a wafer subjected to oxidation before a vapor-growth operation by a method wherein an inert gas jetting hole is provided on the wafer supporting part of a wafer boat so that inert gas can be allowed to flow along the wafer surface while the wafer is being carried in a furnace tube. CONSTITUTION:An inert gas jetting hole 12 is provided on the supporting part of a wafer boat 4 in order to allow inert gas to flow along the surface of a wafer 3.
