Patent ID: 8252383

Claim:
A method for ejecting a liquefied material from an ejection member onto a substrate, the method comprising: detecting a temperature of the liquefied material in the ejection member with a first temperature detector; adjusting the temperature of the liquefied material in the ejection member to a first target temperature with a first temperature regulating element secured to a surface of the ejection member; detecting a temperature of a standby stage with a second temperature detector that is different from the first temperature detector, wherein the standby stage is arranged to oppose the ejection member when the ejection member is held in a standby state; adjusting the temperature of the standby stage with a second temperature regulating element mounted in the standby stage to a second target temperature so that a temperature in a proximity of the ejection member when the ejection member is held in the standby state on the standby stage is substantially equal to the temperature in the proximity of the ejection member when the ejection member ejects the liquefied material onto the substrate, wherein the first target temperature is different from the second target temperature; and moving the ejection member from the standby position to a position at which the substrate is located, thereby performing ejection of the liquefied material onto the substrate;
