Abstract
A seed retaining member has a recessed portion for breaking and separating formed at an arbitrary location and thereby allows stress concentration to occur at the recessed portion when applying a breaking load, to enable the seed retaining member to break with a smaller load than conventional. So that the seed retaining member can prevent a crack from propagating in an unintended location in the seed retaining member by allowing the crack to propagate along the recessed portion, and also can reduce a workload in a separation work of the seed retaining member and polycrystalline silicon.
