Abstract:
1. A method for microdepositing droplets of fluid material using a microdeposition system having a microdeposition head with multiple nozzles that makes multiple passes across a substrate, the method comprising: defining a feature pattern for the substrate; creating a mask based on individual sub-features of the feature pattern; controlling the step of creating a mask to receive the feature pattern and to reduce a density of defects that occur due to at least one of tolerance variations and a malfunctioning nozzle of the microdeposition head; assigning the sub-features of the feature pattern to selected nozzles and selected passes of the microdeposition head based on the mask; generating position control a relative position of the microdeposition head and the substrate; and generating nozzle firing commands to fire the droplets onto the substrate from the selected nozzles during the selected passes to define the sub-features of the feature pattern.
