PROBLEM TO BE SOLVED: To eliminate existing inconvenience such as decrease in laser output and make laser heating possible. SOLUTION: The vacuum processing device is used for vapor deposition while heating a substrate in a vacuum chamber having an optically transparent window in a part thereof. In the vacuum processing device, a holding section for holding the substrate and the optically transparent window are connected in a linear interspace, which is isolated from other places of the chamber. A laser oscillator is arranged outside the optically transparent window and irradiates a laser beam to the substrate through the linear interspace to heat the substrate. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a rapid heat treatment reactor for processing improved semiconductor substrate. SOLUTION: The rapid heat treatment reactor has a rapid heat treatment reaction chamber vessel, a table which is arranged around the rapid heat treatment reaction chamber vessel and comprises a top surface, a shell arranged at a first position so as to contact with the top surface of the table, a rail which is fastened on the table, while extending in a first direction perpendicular to the top surface of the table, and a connection part which is movably connected to the rail so that the shell can be moved to a second position apart from the top surface of the table along the rail, when needed and comprises a plurality of connectors selectively detachable from the shell. When the shell is present at the second position, by detaching one of the plurality of connectors from the shell means, the shell can be made to turn with the left connectors as the axes.
