Patent ID: 7943000

Claim:
A method of fabricating an organic light emitting device comprising: preparing a first substrate and a second substrate; coating a sealant on a portion of the first substrate or the second substrate; loading the first substrate and the second substrate inside a process chamber to load the first substrate and the second substrate on a first substrate supporter and a second substrate supporter, respectively, the process chamber including the first substrate supporter and the second substrate supporter for supporting the first substrate and the second substrate, a substrate detachable part positioned inside the second substrate supporter, and an open-close valve; vacuuming the process chamber; moving the second substrate supporter on which the second substrate is positioned to align the first substrate and the second substrate; detaching the second substrate from the second substrate supporter by applying a physical force from the substrate detachable part to the second substrate to fall down the second substrate onto the first substrate so that the first and second substrates are attached to each other; injecting air into the process chamber through the open-close valve to apply an atmospheric pressure outside of the attached first and second substrates evenly over the whole surface; and hardening the sealant to seal the first and second substrates.
