For some semiconductor metallurgies, an in situ evaporation of Cr followed by Al/Cu is required. The process incorporates a multiple hearth source such as that shown in the IBM Technical Disclosure Bulletin 20, 1738-1739 (October 1977). The multiple hearth source has a plate and shields of stainless steel.
