Patent ID: 7648944

Claim:
A transfer apparatus which transfers a transfer layer provided on a donor substrate onto a receptor substrate, the transfer apparatus comprising: a vacuum chamber having a base including a mount and sidewalls which together form a chamber and which accommodates within the chamber the receptor substrate and the donor substrate, and a cover which covers the base and which forms an upper portion of the vacuum chamber, the cover being a frame having an opening which is smaller than the donor substrate; and a radiation source disposed above the vacuum chamber and which can apply a radiant ray onto the donor substrate, wherein, the vacuum chamber is configured to clamp the receptor substrate and the donor substrate together by means of the mount and an upper portion of the vacuum chamber, the mount is fixed at a position where the receptor substrate and the donor substrate are stacked, the opening is closed by the donor substrate placed on the mount with the receptor substrate therebetween such that an airtight space is formed by the donor substrate, the cover and the base, the cover is spaced from the mount such that only the donor substrate and the receptor substrate are accommodated between the cover and the mount, and the radiation source can apply the radiant ray onto the donor substrate via the cover opening.
