The invention is a carrier comprising three support elements connected by an underlying frame. The periphery of a wafer rests upon the support elements. The invention also comprises a wafer handler with a plurality of arms. Spacers space the carrier above a base plate associated with a station in a wafer handling area. An arm slides beneath the frame and between the spacers, but the handler does not contact the wafer. A method of using the handler and carrier is provided where the handler lifts and rotates the carrier with the wafer through various stations in a wafer handling area. A control device reduces the handler speed only at critical points of the processing cycle. The handler is capable of moving a plurality of carriers and wafers simultaneously.
