Inventor: WADA MASAHIRO
IPC: H01L21/67
Filed: 2019-10-10
Abstract: An objective of the present invention is to easily perform position determination of a ring frame held by a sucker. In a ring frame holding mechanism (10), an air layer is formed between the upper surface (13) of a table (11) and the lower surface of a ring frame (1) by air ejected from a sucker (41) when determining the position of the ring frame (1). The ring frame (1) and the sucker (41) are in a non-contact state by the air layer. The sucker (41) is pressed downwards to allow the upper end (41a) of the sucker (41) and the upper surface (13) of the table (11) to become the same plane. Therefore, since the ring frame (1) can be separated from four suckers (41), a position determination unit (21, 23, 25, 27) allows the ring frame (1) to easily side-slip. Therefore, the ring frame (1) is easily position-determined at a target position to suppress position determination defects.
