Patent ID: 7611754

Claim:
A microdeposition system for microdepositing droplets of fluid material onto a substrate, comprising: a microdeposition head that includes a plurality of spaced nozzles; a positioning device that controls a position of said microdeposition head relative to said substrate; and a controller including: a receiver that receives a feature pattern; a mask generating module that creates a mask based on said feature pattern to reduce a density of defects that occur due to at least one of tolerance variations and a malfunctioning nozzle of said microdeposition head, and that assigns sub-features of said feature pattern to selected nozzles and selected passes of said microdeposition head based on said mask; a positioning module that communicates with said positioning device and that generates position control signals for said positioning device based on said selected passes, and a nozzle firing module that communicates with said microdeposition head and that selectively generates nozzle firing commands to fire said droplets from said selected nozzles onto said substrate during said selected passes to define said sub-features of said feature pattern.
