ALIGNMENT METHOD, ALIGNMENT APPARATUS, AND ORGANIC EL ELEMENT MANUFACTURING APPARATUS

摘要

Provided are an alignment method and an alignment apparatus, in which the number of times to carry out alignment operation is reduced to reduce damage of a substrate and a mask and improve the productivity of evaporation using the mask. Vibrations in the direction of gravity of a substrate immediately after the substrate is brought in are measured by a laser vibrometer. Based on the obtained vibration data, a vibration control portion generates an antiphase vibrational wave. After the vibrational wave is applied to the substrate to reduce the vibrations of the substrate, the alignment between the substrate and a mask is carried out.
