Abstract:
1. An epitaxial growth furnace comprising: a sealed chamber; a pair of wafer holders for holding a pair of semiconductor wafers within said chamber; and means for rotating each of said wafer holders within said chamber, wherein formation of an epitaxial layer on a surface of each of said wafers is effected by supplying under a high temperature condition a source gas to a surface area of each of said wafers; wherein said wafer holders are rotatably supported at the peripheral thereof within said chamber and adapted to arrange said pair of wafers in such a manner that the wafers are disposed in mutually opposing positions with each said surface area adjacent to and parallel with each other so that a reaction chamber is formed between said wafers; wherein said surface areas are subject to epitaxial growth within said reaction chamber; wherein each of said wafer holders comprises: wherein said means for rotating each of said wafer holders comprises:
