Patent ID: 7374262

Claim:
A pattern producing apparatus comprising: a stage for placing a substrate, a position adjusting mechanism for adjusting the relative positional relationship between the stage and a head unit comprising a plurality of integrated heads, and a control section for discharging liquid droplets from each integrated head while thinning out the liquid droplet discharge of each integrated head according to a predetermined rule such that the liquid droplet amount per unit area to be impacted on the substrate is made even between each integrated head, wherein forming the pattern on the substrate by discharging a plurality of liquid droplets from each head to the substrate while changing relative position of the head unit containing a plurality of integrated heads and the substrate, wherein the control section comprises a memory section for storing discharging position information, preliminarily determined for the each head, showing the position on the substrate of the liquid droplets to be impacted so that the liquid droplet discharged from the each head is controlled based on the discharging position information read out from the memory section, and further wherein the discharging position information is determined such that the position of thinning out the liquid droplet discharge is dispersed substantially even in the pattern formed on the substrate.
