Abstract:
1. An attaching device comprising: a process chamber; a first and a second substrate supporters that are positioned inside the process chamber to load and fix a first and a second substrates, respectively; a substrate detachable part that is positioned inside the second substrate supporter, and moves down to instantaneously apply a physical pressure to the second substrate to push and detach the second substrate from the second substrate supporter, wherein the second substrate free-falls down onto the first substrate; and an open-close valve that is positioned on a portion of the process chamber, and opens and closes the process chamber to control a pressure inside the process chamber, wherein the open-close valve is closed to maintain inside of the process chamber in a vacuum state for attaching the first and second substrates, and the open-valve is configured to make inside of the process chamber in an atmospheric pressure state for closely attaching the first and second substrates.
