Patent ID: 7105841

Claim:
A raster-based photolithographic system for forming orthogonal and non-orthogonal images on a reticle, comprising: an imager and a worktable adapted to function to orthogonally image the reticle in an X direction and a Y direction using a raster motion, and to adjust a rotational position of the reticle with respect to the raster motion; a database, including a first data set for writing an orthogonal image with respect to the raster motion and a second data set corresponding for writing a non-orthogonal image with respect to the raster motion; an X-controller to control imaging of reticles in an X direction; a Y-controller to control imaging of reticles in a Y direction; and a θ-controller to control an adjustment of the rotational position of the reticle with respect to the raster motion.
