Abstract
A shower head for a chemical vapor deposition chamber can have a housing, a plurality of bosses formed upon the housing, and an inside cover. The bosses can have bores formed therethrough. The inside cover can be attached to the bosses and can have apertures formed therein such that the apertures are generally contiguous with the bores. The housing, the bosses, and the inside cover cooperate to communicate water through the shower head. The water can cool the shower head to a temperature that is substantially lower than the temperature of other parts of the chemical vapor deposition chamber, e.g., the susceptor thereof.
