Imaging or exposure device, in particular for making an electronic microcircuit
摘要:
The imaging or exposure device comprises a radiation source (1), a reticle (3) mounted between the radiation source and an optical projection system (4) for shaping the radiation downstream from the reticle (3), the optical projection system (4) comprising a series of mirrors (7, 8, 10, 11) including at least two mirrors (10, 11) that are deformable, having deformer members (12, 13) connected to a control unit (14) associated with an image analyzer (15) to deform the two deformable mirrors in separate manner, firstly as a function of differences relative to an image quality setpoint, and second as a function of differences relative to an image distortion setpoint.
