DRILLED CVD SHOWER HEAD

摘要

A shower head for a chemical vapor deposition chamber can comprise a plurality of first injectors for a first reactant gas and a plurality of second injectors for a second reactant gas. The first and second injectors can be interspersed among one another so as to enhance control of the mixing and delivery of reactant gases within the chemical deposition chamber. Cooling water can be communicated through a plurality of gun drilled bores formed intermediate injectors of the shower head. In this manner, enhanced control of the mixing and delivery of reactant gases can be provided.
