Abstract: A system (10) is disclosed for cleaning a vertical furnace (12) pedestal (34) and cap (36) including at least one inlet conduit (40) in fluid communication with a pressurized cleaning medium source (46). The system also includes at least one exhaust conduit (42) in fluid communication with a negative pressure source (48). A boat assembly (30) may be positioned such that the at least one conduit (40) is operable to direct cleaning medium at the boat assembly (30) to dislodge contaminate particles associated with the boat assembly. The exhaust outlet (42) then evacuates the cleaning medium and any dislodged contaminate particles. The system may operate automatically within a closed processing environment and after each process cycle.

Abstract: A method for reducing thickness of spin-on glass on semiconductor wafers includes rotatably mounting a semiconductor wafer and positioning a grinding member proximate an outer edge of the semiconductor wafer. The method further includes rotating both the semiconductor wafer and the grinding member, and engaging the rotating grinding member with the outer edge of the rotating semiconductor wafer while applying a chemical to the outer edge.
