  • Patent number: 7133121
    Abstract: A method and system are provided for printing a pattern on a photosensitive surface using a spatial light modulator (SLM). An exemplary method includes defining two or more exposure areas on the photosensitive surface, the exposure areas overlapping along respective edge portions of the exposure areas to form an overlap zone therebetween. Two or more exposure areas are exposed to print an image therein, the exposing extending through the overlap zone. The exposing within the overlap zone is then attenuated.

  • Patent number: 7130020
    Abstract: A photolithographic machine is described for transferring fine patterns from a photomask to a flexible roll-to-roll format. It is capable of printing multiple layers in exact registry onto a distorted format. It contains 1 to 1 reflective optics, dynamic distortion and magnification correction. The optical transfer assembly scans reciprocally across the format and back and the photomask/platen assembly moves incrementally forward between scans to complete a raster pattern. Both the object and image fields are autofocussed. The optical transfer assembly is retained into a straight-line scanning path by opposed air bearings retained on a straight guide. The photomask/platen assembly is retained into an orthogonal path by air/vacuum bearings operating on a vertical stone face. Together this arrangement substantially prevents yaw scanning errors. The web is fed through the machine from roll to roll without twisting. It remains stationary during each recording pass.

    Abstract: A projection exposure apparatus includes a diaphragm controlling unit controlling one or more of an diaphragm, an iris diaphragm, and a relay lens system. In addition, the projection exposure apparatus also includes a line width calculator which calculates a bias, which is a difference between a line width in a dense part and a line width in an isolated part, based on information regarding a mask pattern, the wavefront aberration of a lens, the effective light source of an illumination optical system, the half-width of a laser, the temperature change in a projection optical system due to exposure, etc. When the bias is out of a tolerance range, the line width calculator calculates a correction value for the diaphragm of the projection optical system or a correction value for the effective light source of the illumination optical system in accordance with the bias which is to be corrected. Then, the diaphragm controlling unit is driven in accordance with the calculation results.
