Abstract : The patent describes a furnace useful in treating semiconductor wafers by means of a gas atmosphere. The furnace is oriented vertically and comprises an outer chamber provided with gas inlet and gas outlet ports; means for creating turbulence in the admitted gas and means for imparting motion to the wafers to insure that the wafers are uniformly acted upon by the gas; means for providing the wafers with an inert gas cover when no treatment is desired; and means for safely removing residual gas from the furnace.
