Proximity exposure system that positions masks vertically to reduce the chance of distortion. lnline installation is possible with upstream/downstream systems of the horizontal transfer type.

Main feature

  • The mask holder and the substrate stage stand upright, which eliminates any compensation for self-weight bending of the mask / the mask holder / the substrate stage, realizing a simple and stable system.
  • With the newly adopted optical system, a parallel light source is employed so that the declination angle, which affects the transcription accuracy, is reduced by half, compared with previous models, thereby achieving more accurate transcription of pattern images.
  • The main body and the lamp housing are completely separate. This structure isolates heat from the lamp housing and improves the heat distribution property in the main body.
  • To prevent expansion/shrinkage by temperature difference between a mask and a glass substrate, a substrate stage thermocontroller and a mask cooling system are available (optional).
  • Max. substrate size is 1,200mm x 1,400mm. Further, our original optical system enables a uniform one-shot exposure.
  • A mask library storing up to 5 masks can be integrated.
