Abstract:
A method of forming a thin film, wherein a sample boat having an EL material contained therein a substrate having an electrode provided thereon, and a mask between the sample boat and the substrate are provided,wherein the EL material is made to be in a vapor state in the sample boat, wherein the EL material in the vapor state is discharged from the sample boat toward the substrate, wherein the EL material in the vapor state is made to pass through an opening of the mask corresponding to the electrode, and to deposit the EL material on the electrode over the substrate in order to form a thin film, and wherein voltage is applied to the mask in order to control the deposition location of the EL material, and wherein voltage is applied to the electrode in order to control the deposition location of the EL material.
