Abstract
A system for identifying wafers contained in a wafer carrier includes a wafer sorter. Each wafer includes a surface terminating in an edge and a plurality of sector identification codes disposed on the surface proximate the edge. The wafer sorter is adapted to scan at least a portion of a wafer extending from the carrier and to identify at least one of the sector identification codes on the wafer independent of the orientation of the wafer in the wafer carrier. A method for identifying wafers contained in a wafer carrier is provided. Each wafer includes a surface terminating in an edge and a plurality of sector identification codes disposed on the surface proximate the edge. The method includes scanning at least a portion of a wafer extending from the carrier and identifying at least one of the sector identification codes on the wafer independent of the orientation of the wafer in the wafer carrier.
