The accuracy with which European metrology laboratories can measure photomask linewidths for the microelectronics industry has been evaluated by a measurement audit. This report describes the techniques that can be used and discusses the performance of those techniques actually employed in the exercise. The achievement of accuracies of a few hundredths of a micron in the measurement of linewidths down to below 1 micron is demonstrated, and the necessary measurement practice and precautions described.
