Assembly method for vacuum processing apparatus
The disclosure provides an assembly method of a vacuum processing apparatus having a reaction vessel and an exhaust port that are made of quartz and airtightly connected to each other, in order to prevent breakage of the vessel. The method includes (a) mounting an attachment member on one end portion of the reaction vessel, (b) connecting and fixing at least a flange portion of an exhaust pipe to the exhaust port, (c) fixing the attachment member to a portion of the exhaust pipe including at least the flange portion connected and fixed to the exhaust port by using fixing members after (a) and (b), (d) fixing the attachment member to a support portion after (a), and (e) fixing the exhaust pipe to an exhaust pipe fixing portion different from the attachment member at a lower position than a fixing position of the attachment member after completing (a) to (d).
1. An assembly method of a vacuum processing apparatus which performs a vacuum process on a substrate in a depressurized atmosphere in a reaction vessel being made of quartz and having one end portion open as a loading port of the substrate and an exhaust port formed at said one end portion, the method comprising:
(a) mounting an attachment member on the one end portion of the reaction vessel;
(b) connecting and fixing at least a flange portion of an exhaust pipe to the exhaust port;
(c) fixing the attachment member to a portion of the exhaust pipe including at least the flange portion connected and fixed to the exhaust port by using fixing members after (a) mounting and (b) connecting and fixing;
(d) fixing the attachment member to a support portion after (a) mounting the attachment member on the reaction vessel; and
(e) fixing the exhaust pipe to an exhaust pipe fixing portion different from the attachment member at a lower position than a fixing position of the attachment member after completing (a) mounting to (d) fixing.
2. The method of claim 1 , wherein the reaction vessel is a vertical reaction vessel into which a holding unit including a plurality of substrates stacked in a form of shelves is loaded from a lower end portion of the reaction vessel which is the one end portion, and
the fixing members are fixed to the flange portion of the exhaust pipe, which is connected to the exhaust port.
3. The method of claim 1 , wherein the flange portion is detachably installed on one end portion of the exhaust pipe, and
(b) connecting and fixing the flange portion of the exhaust pipe to the exhaust port is fixing the flange portion to the exhaust port in a state where the flange portion is separated from the exhaust pipe,
the method further comprising connecting and fixing the flange portion to one end portion of the exhaust pipe after (c) fixing the attachment member to the flange portion by using the fixing members; and
(e) fixing the exhaust pipe to the exhaust pipe fixing portion is performed after connecting and fixing the flange portion to one end portion of the exhaust pipe.
4. The method of claim 1 , wherein the fixing members are arranged in at least three locations to be spaced from each other around an axis extending in a longitudinal direction of the exhaust port, and
each of the fixing members is arranged to face another one of the fixing members through an inner region of the exhaust port.
5. The method of claim 1 , wherein the fixing members are configured such that a length dimension between the portion of the exhaust pipe and the attachment member is adjustable.
6. The method of claim 1 , wherein a bellows member is interposed between a position at which the exhaust pipe is fixed to the exhaust pipe fixing portion and a position at which the exhaust pipe is fixed to the attachment member by using the fixing members.
7. The method of claim 1 , wherein the fixing members are configured such that the angles of connection portions connected to a portion of the exhaust pipe and the attachment member respectively is adjustable.
8. An assembly method of a vacuum processing apparatus which performs a vacuum process on a substrate in a depressurized atmosphere in a reaction vessel being made of quartz and having one end portion open as a loading port of the substrate and an exhaust port formed at said one end portion, the method comprising:
(a) mounting an attachment member on the one end portion of the reaction vessel;
(b) connecting and fixing at least a flange portion of an exhaust pipe to the exhaust port;
(c) fixing the attachment member to a support portion after (a) mounting the attachment member on the reaction vessel;
(d) fixing the exhaust pipe to an exhaust pipe fixing portion; and
(e) fixing the attachment member to a portion of the exhaust pipe including at least the flange portion connected and fixed to the exhaust port after completing (d) fixing,
wherein a bellows member is interposed between a position at which the exhaust pipe is fixed to the exhaust pipe fixing portion and a position at which the exhaust pipe is fixed to the attachment member by using the fixing members.
