Abstract
Abstract A semiconductor wafer receiving apparatus has a base, a table for supporting a wafer, a receiving member having at least three receiving pins which project from a supporting surface and are concealed under the supporting surface upon vertical movement of the table, and a driving unit for vertically moving the table. The wafer is transferred onto the receiving pins while the receiving pins project, and is held on the table while the receiving pins are concealed.
