Patent ID: 6966952

Claim:
A deposition apparatus comprising: a deposition boat installed in the vacuum chamber to vaporize the deposition material; a wafer guide having a rotational member which is rotated together with the wafer; a wafer-rotation device rotating the rotational member when the wafer guide approaches, wherein the vapor deposition boat is installed at a first position that defines a vapor deposition zone at the first position, the wafer-rotation device being installed at a second position that is laterally separated from the first position and outside the vapor deposition zone such that the wafer rotation device is adapted to rotate the rotational member while the rotational member is outside the vapor deposition zone; and a wafer-transfer device which reciprocates the wafer guide between an inlet of the vacuum chamber and vapor deposition zone and between the vapor deposition zone and the wafer-rotation device via the deposition boat.
