Patent ID: 7704653

Claim:
A method for writing pattern data patterns onto a substrate with charged particle beam lithography using a selectively patterned charged particle beam, the method comprising: a) condensing an initial design pattern down to a set of profiles and associated locations for the profiles to form a formatted set of pattern records, the initial design containing pattern information that defines a desired pattern of features to be formed on a die and wherein the profiles define shapes and patterns that enable patterns to be transferred to the surface during charged particle lithography; b) adjusting the formatted set of pattern records to accommodate desired pattern corrections; c) extracting portions of the formatted set of pattern records to form a plurality of data streams each comprising a plurality of channels with each channel comprising a pattern of profiles and spatial indicators that specify a location for an associated profile, thereby enabling the initial design data to be defined by data streams of simplified instructions; d) sequentially reading the data streams to reconstruct the initial design as a printable pattern of profiles and spatial indicators specifying the locations of the profiles; and e) sequentially printing a pattern of profiles from each data strip onto a substrate at an appropriate location to thereby print the initial design pattern on the substrate.
