Abstract
In a vertical type wafer supporting jig, a ring-like support plate is fixed to support pillars by a simple structure without conventional welding and without risk of the ring-like support plate falling off. The vertical type wafer supporting jig is configured for mounting many wafers onto many support plates stacked in a vertical direction and fixed to support pillars with a predetermined wafer mounting interval between the support plates. Support groove portions into which the support plates are inserted and supported are formed in the support pillars with a predetermined interval in the vertical direction between them. A fixing rod is provided adjoining at least one of the support pillars. A peripheral part of the support plate has at least one receiving groove corresponding to the fixing rod, and the support plate is fixed to and supported by the support pillars by inserting the support plate into the support groove part, in which it is supported, and fitting the fixing rod into the receiving groove of the support plate.
