Abstract:
A vapor deposition apparatus for supplying raw-material gas into a reactor to form a thin film on a wafer substrate disposed in the reactor by vapor deposition, characterized by including: at least a rotator which is disposed in said apparatus and adapted to mount the wafer substrate thereon, a treatment gas introducing port which is disposed at the top portion of said apparatus, a straightening vane having plural holes which is disposed at the upper portion in said apparatus, and a wafer substrate feed-in/out port at the side portion of said apparatus, wherein the lowermost portion of said wafer feed-in/out port is located at a position higher than the upper surface of said rotator, and the difference in height (I(mm)) between the lowermost portion of said wafer feed-in/out port and the upper surface of said rotator is set to be larger than the thickness of a transition layer (T) of the upper portion of said rotator (I>T).
