Abstract: A method of measuring wear of a substrate holder that is configured to hold a production substrate, the method includes: clamping a measurement substrate to the substrate holder; and measuring strain in the measurement substrate to generate a measurement result. The measurement substrate may have a body having dimensions similar to that of the production substrate; and a strain sensor in the body configured to measure strain in a peripheral portion of the measurement substrate.

Abstract: Method for calculating a reparation dose for a die of a substrate, the method including: a) obtaining a function of a distribution of an energy dose applied to the die over time based on a measurement of exposure energy, b) determining energy dose in a timeslot with a reparation point in the centre of the timeslot, c) calculating a slope of the function in the timeslot to determine at least one measurement point, the at least one measurement point being positioned within the timeslot based on the slope of the function in the timeslot; d) calculating a reparation dose at the measurement point; e) calculating a repair energy based on the reparation dose; f) updating the function over the timeslot based on applying the repair energy at the reparation point.
