In this study, an inverse algorithm based on the conjugate gradient method and the discrepancy principle is applied to estimate the unknown space- and time-dependent Biot number in deep X-ray lithography using temperature measurements. It is assumed that no prior information is available on the functional form of the unknown Biot number; hence, the procedure is classified as the function estimation in the inverse calculation. The accuracy of the inverse analysis is examined by using simulated exact and inexact temperature measurements. Results show that an excellent estimation of the space- and time-dependent Biot number can be obtained for the test case considered in this study.
