Abstract:
A combination of a substrate transport container and an automatic door opener configured to open and close automatically a wafer loading/unloading door of a substrate transport container;wherein said automatic door opener has charging terminals for automatically charging a secondary battery of said substrate transport container when said substrate transport container is placed on said automatic door opener; wherein said substrate transport container comprises: a carrier box including a container body and said wafer loading/unloading door sealably covering an opening provided in a front or a bottom of said container body; partitions configured to form a circulating flow path in said carrier box, said circulating flow path having a flow path in which air flows toward substrates and a flow path in which air flows toward a fan; a substrate carrying section disposed in said flow path in which air flows toward the substrates to carry the substrates in such a way that principal surfaces of the substrates are approximately parallel to said flow path in which air flows toward the substrates; a combination of a particle removing filter and a gaseous impurity trapping filter placed on an upstream side of said substrate carrying section in said flow path in which air flows toward the substrates; and a fan motor incorporated in said carrier box and configured to drive said fan to form an air current for circulating through said circulating flow path.
