Abstract: Methods and systems for calibrating system parameter values of a target inspection system are presented. Spectral Error Based Calibration (SEBC) increases consistency among inspection systems by minimizing differences in the spectral error among different inspection systems for a given specimen or set of specimens. The system parameter values are determined such that differences between a spectral error associated with a measurement of a specimen by the target inspection system and a spectral error associated with a measurement of the same specimen by a reference inspection system are minimized. In some examples, system parameter values are calibrated without modifying specimen parameters. Small inaccuracies in specimen parameter values have little effect on the calibration because the target system and the reference system both measure the same specimen or set of specimens. By performing SEBC over a set of specimens, the resulting calibration is robust to a wide range of specimens under test.

Abstract: A method is proposed for the simultaneous optimization of an arbitrary number of electromagnetic pulses, which act in a cooperative way, or mutually compensate each other's errors. The method generally relates to pulses which can have improved properties when cooperating with each other compared to single pulses. In experiments with several scans, undesired signal contributions can be suppressed by COOP pulses, which complements and generalizes the concept of phase cycling.

COOP pulses can be optimized efficiently with the aid of an extended version of the optimal-control-theory-based gradient ascent pulse engineering (GRAPE) algorithm. The advantage of the COOP pulse method is demonstrated theoretically and experimentally for broadband and band-selective excitation and saturation pulses.
