Baffled box sources for SiO, ZnS
The “Baffled Box” Silicon monoxide source, SiO source, has proven to be an extremely successful method of depositing Silicon Monoxide. Source material is positioned in the boat within separate cavities, when heated it follows an indirect path through a series of baffles and then out of the exhaust chimney.
The substrate cannot see the bulk material at any time. This essentially eliminates any chance of spitting and streaming which causes pinhole type defects. Many of the sources shown are available with up, down or horizontal exhaust ports.
