    Abstract: A transport vehicle includes a holder and a lifter. The lifter includes an elongated member and a lifting unit. The holder includes a support, at least one first holder member, at least one second holder member, and a holder drive. The first holder member and the second holder member are located below the support. The holder drive is located in a space in a vertical direction below the support. The space includes the first holder member and the second holder member. The elongated member fastener fastening an elongated member to the support is located on the support. The elongated member fastener protrudes downward from the support.

    Abstract: Some implementations described herein provide a method that includes loading, from a load port and into a first buffer of a multiple-buffer overhead hoist transport (OHT) vehicle, a first transport carrier storing one or more processed wafers. The method includes unloading to the load port, while the first buffer retains the first transport carrier, and from a second buffer of the multiple-buffer OHT vehicle, a second transport carrier storing one or more wafers for processing. In other implementations, the method includes loading, into a first buffer of the multiple-buffer OHT vehicle, a first transport carrier storing one or more wafers for processing, while a semiconductor processing tool, associated with a load port, is processing one or more wafers associated with a second transport carrier. The method includes positioning the multiple-buffer OHT vehicle above the load port while the multiple-buffer OHT vehicle retains the first transport carrier in the first buffer.
