Abstract
The present invention relates to a process for irradiating a processed surface (5) of a processed substrate (1) so as to obtain a predefined temperature profile, the processed surface (5) comprising a first area (11) and a second area (13), said first area (11) having a first combination of optical properties and thermal properties, and said second area (13) having a second combination of optical properties and thermal properties, said first combination and second combination being different. A further object of the invention is a system (21) for irradiating a processed surface (5) of a processed substrate (1) so as to obtain a predefined temperature profile, the processed surface (5) comprising a first area (11) and a second area (13), said first area (11) having a first combination of optical properties and thermal properties, and said second area (13) having a second combination of optical properties and thermal properties, said first combination and second combination being different.
