Patent ID: 8586488

Claim:
A computer program product, comprising a computer readable hardware storage device having a computer readable program code stored therein, said computer readable program code configured to be executed by a processor of a computer system to implement a method for configuring radiation sources to simultaneously irradiate a substrate, said method comprising: said processor specifying J electromagnetic sources of radiation, wherein a power distribution of emitted radiation for each source of the J sources is a different function of wavelength and angular distribution of the emitted radiation, said J≧2; said processor specifying the substrate, said substrate comprising a base layer and I stacks on the base layer, said I≧2, wherein P j denotes a same normally incident energy flux on each stack from source j such that P j is specific to source j for j=1, 2, . . . , J; said processor specifying a target energy flux S i targeted to be transmitted via each stack i into the substrate such that S i is specific to each stack i; and for simultaneous exposure of the I stacks to electromagnetic radiation from the J sources, said processor calculating each P j such that an error E being a function of |W 1 −S 1 |, |W 2 −S 2 |, . . . , |W I −S I | is about minimized with respect to P j for j=1, 2, . . . , J, wherein W i denotes an actual energy flux transmitted into the substrate via stack i for i=1,2, . . . , and I.
