Abstract: A storage system for storing material such as sample tube caps comprises a drawer with a reservoir, the drawer being movable between a first position and a second position. A storage container is arranged below the reservoir of the drawer when the drawer is arranged in the first position. A transport device is configured to retrieve material from the storage container and to transport the material out of the storage container. Therein, the reservoir of the drawer comprises a bottom with at least one closable opening.

Abstract: A holder manufacturing method for loading a substrate of a semiconductor manufacturing device, a batch type boat having the holder, a loading/unloading method of a semiconductor substrate using the same, and a semiconductor manufacturing device having the same are disclosed. For example, the manufacturing method of the holder of the boat for loading a semiconductor substrate includes the steps of molding a holder substrate of a pipe shape having inner and outer circumference of a predetermined size in such a manner that a lower portion of the semiconductor substrate is seated thereon; and forming a plurality of holder rings by cutting the holder rings from the holder substrate in such a manner that each holder ring is matched to a disposal interval of the semiconductor substrates in the boat.
