Abstract:
1. A wafer transfer equipment, comprising: first and second wafer carriers with grooves to hold a plurality of wafers in the grooves in an erected state; first and second wafer elevators each equipped with a comb-teeth portion to hold the plurality of wafers and provided to correspond to the first and second wafer carriers, each of the comb-teeth portions including comb-teeth members; and wafer transfer units to transfer the plurality of wafers from the first wafer carrier to the second wafer carrier; wherein the first and the second wafer elevators are further equipped with a position correction mechanism to correct positions of the comb-teeth members by moving the comb-teeth members back and forth in a direction along which the comb-teeth members are arranged when the plurality of wafers held in the grooves of the first or second wafer carriers touch the comb-teeth members of the first or second wafer elevators, respectively.
