Abstract:
1. A semiconductor wafer mount apparatus for manufacturing a mount frame, the semiconductor wafer mount apparatus comprising: a stack of semiconductor wafers each having an annular convex portion left on an outer periphery of a back face thereof; a grinding unit for removing the annular convex portion formed at the outer periphery of the back face of a semiconductor wafer so as to surround a flat concave portion formed by back grinding such that the semiconductor wafer has a uniform thickness; a transport unit for allowing a robot arm to take the semiconductor wafer, from which the annular convex portion has been removed, and to transport the semiconductor wafer to a subsequent step; an inspection unit for inspecting whether or not damage occurs at the outer periphery of the semiconductor wafer which has been subjected to the removal of the annular convex portion; and a mount frame preparation unit for joining the semiconductor wafer transported by the robot arm to the ring frame through the adhesive tape to prepare the mount frame, wherein the mount frame preparation unit includes: an alignment stage for holding the semiconductor wafer placed thereon by the robot arm such that the front face of the semiconductor wafer, to which the protective tape is joined, is directed upward; joining means for transporting the semiconductor wafer subjected to alignment in the alignment stage to a joining section, and joining the semiconductor wafer to a adhesive surface of the adhesive tape joined to the ring frame; and a protective tape separation mechanism for separating the protective tape from the front face of the semiconductor wafer in the prepared mount frame.
