  • Publication number: 20060219162
    Abstract: A process for making silicon ingots using a multi-part, reusable, graphite crucible of at least two mold pieces configured for assembly into an open top mold having an interior surface functional as a mold cavity for receiving molten silicon; removing or reducing a prior applied release coating from the interior surface until a uniformly smooth finish is achieved; coating the interior surface with a first layer of release coating comprising silicon nitride; coating the interior surface with a second layer of release coat comprising silica suspended in water; coating the interior surface with a third layer of release coat comprising silicon nitride; curing the release coat on said crucible; casting a silicon ingot in the crucible; and then repeating the prior steps multiple times.

  • Patent number: 6508259
    Abstract: A pressure vessel for use in production processes requiring elevating and ranging of temperatures and pressures during the process cycle, readily adaptable to production line operation, suitable for wafer processing in the semiconductor industry and for other industries and processes. The pressure vessel is configured within an open support frame with a stationary, preferably inverted, orientation. The cover or closing plate is vertically movable towards the mouth of the pressure vessel and functions as the platform by which the object under process is transferred into the vessel. The moving and locking mechanism for the cover is isolated and shielded from the process environment.
