ABSTRACT:
A rack for supporting wafers has a pair of parallel struts with kerfs therealong for supporting the wafers. A dummy wafer is attached to the struts near each end of the struts to connect the struts structurally as the rack and serve as rack-handling handles. The dummy wafers are parallel to the adjacent kerfs and thus the wafers therein and dimensioned similarly to the wafers for providing favorable gas and heat distribution when a wafer loaded rack is placed in a furnace. This adapts the rack for diffusion treatment of semiconductor wafers.
