Abstract
A vapor deposition apparatus includes a disc-shaped susceptor and a susceptor support member that supports and rotates the susceptor. The susceptor has a plurality of fitting grooves. The susceptor support member is provided with a plurality of support pins to be fitted in the respective plurality of fitting grooves. The fitting grooves each have an inclined portion that relatively moves the support pin with respect to the fitting groove in a circumferential direction of the susceptor with the support pin kept in contact by virtue of a self-weight of the susceptor and a positioning portion that positions the support pin relatively moved by the inclined portion at a specific position in the circumferential direction. The inclined portion and the positioning portion are formed continuously in a radial direction of the susceptor.
