Abstract
PURPOSE:To prevent the dissipation of undesired impurity from the back surface of a water of disposing and heat treating many sets of two sheets of semiconductor wafer having no mask material on the back surface and intimately contacted between the back surface of the wafers in an oven at the prescribed interval. CONSTITUTION:An N<+>N<-> type semiconductor wafer 30 having an N<+> type region 31 and an N<-> type region 32 is prepared, and silicon dioxide films 33, 34 are selectively formed on the surface by an ordinary method. Many sets of two sheets of semiconductor wafers 30a, 30b intimately contacted back-to-back surface B are then formed, are implanted and supported on a boat 26 at the prescribed interval g, and are inserted into an oven 20. When the wafers are then heat treated in an impurity atmosphere, a P type impurity is diffused, and a P type base region 36 is then selectively formed in the region 32. When an N type impurity is similarly diffused, an N type emitter region 37 is formed. Thus, it is not necessary to form a mask material on the back surfaces B.
