include 26 uppercase letters, 10 numbers, dash and period. Their shapes and dimensions are specified by SEMI M12/M13 standard, which was approved by Global Traceability Committee and North American Traceability Committee. When used in “single-density” mode, laser scribers use a dot matrix of 5 dots horizontal and 9 dots vertical, in “double-density” mode, the matrix is 10 dots horizontal and 18 dots vertical.
