Patent ID: 8664107

Claim:
A liquid material application method comprising the steps of creating a desired application pattern, discharging a liquid material from a nozzle while the nozzle and a workpiece are moved relative to each other, and filling the liquid material into a gap between a substrate and the workpiece by capillary action, the workpiece being placed on the substrate with three or more bumps interposed therebetween, the method further comprising: an initial parameter setting step of specifying, as a total pulse number, the number of times of transmitting a discharge pulse signal and a pause pulse signal, specifying, of the total pulse number, the number of discharge pulse signals necessary to achieve a required application amount of the liquid material, and specifying the rest as the number of pause pulse signals; a correction amount calculating step of measuring a discharge amount of the liquid material from a discharging device, and calculating a correction amount of the discharge amount; and a discharge amount correcting step of adjusting the number of discharge pulse signals and the number of pause pulse signals on the basis of the correction amount calculated in the correction amount calculating step, wherein when the bumps are non-uniformly arranged, the number of the discharge pulse signals per unit area is adjusted in the discharge amount correcting step to be larger in an application region adjacent to an area having a higher integration degree of the bumps than in an application region adjacent to an area having a lower integration degree of the bumps.
