Patent ID: 8906599

Claim:
A method for patterning a substrate, said method comprising: providing a substrate that is divided into a plurality of die arranged in columns and rows; providing an illumination source, a reticle and a projection lens; patterning said substrate with a pattern from said reticle by projecting a beam from said illumination source through said reticle and said projection lens and onto said substrate by scanning by carrying out a plurality of scans, each said scan comprising continuously translating said substrate relative to said beam in a continuous linear scan along a complete one of said columns in a scan direction, wherein said patterning a substrate includes forming said beam by directing light from said illumination source through an exposure slit and translating said reticle relative to said beam during said scanning, said translating said reticle including translating said reticle along said scan direction to form a first die of said plurality of die and translating said reticle along a direction opposite said scan direction to form an adjacent second die of said plurality of die along a first column of said columns of said scan direction.
