摘要:
A process and apparatus for the low pressure, cold wall, chemical vapor deposition of refractory metals, such as tungsten on a silicon wafer. The silicon wafer is introduced into a loading lock wherein the pressure is reduced to subatmospheric pressure. The silicon wafer is transferred to a deposition chamber where it is heated to an elevated temperature. A refractory metal carbonyl vapor is introduced into the deposition chamber and dissociates to deposit a refractory metal on the silicon wafer. The wafer is transferred to an unloading lock where it is allowed to cool and is then removed.

摘要:
A method of performing a liquid etching operation on a wafer surface includes placing the wafer into an etch container, filling the etch container with a liquid etch solution, retaining the etch solution in the etch container for a short predetermined length of time, releasing the etch solution from the etch container, and then repeating the above steps without replacing the wafer, to obtain a series of short etch cycles having collectively a predictable average etch rate.
