Abstract

In one embodiment, an in-line furnace includes a continuous conveyor configured to hold wafers at an angle relative to ground. The conveyor may have fixedly integrated wafer retainers configured to hold the wafers in slots. The conveyor may be formed by several segments that are joined together. Each of the segments may include a base and a set of wafer retainers formed thereon. The conveyor may be driven to move the wafers through a chamber of the furnace, where the wafers are thermally processed.
