Claim:
1. A method of making a monolithic ceramic a gas stick usable in a gas delivery system of a semiconductor substrate processing apparatus, the method of making the monolithic ceramic component comprising: preparing a green compact of ceramic material; forming the green compact of ceramic material into a form of a desired monolithic ceramic gas stick having a plurality of inlet ports and a plurality of outlet ports and one or more conduits in fluid communication with the inlet and outlet ports, wherein the green compact of ceramic material is formed around a preform having a shape corresponding to an internal cavity structure of the monolithic ceramic gas stick; removing the preform from the formed green compact of ceramic material by heating the preform to thereby facilitate removal of the preform from the formed green compact of ceramic material; and firing the formed green compact of ceramic material to form the monolithic ceramic gas stick of the gas delivery system.
