Patent ID: 7204886

Claim:
An apparatus for performing multiple deposition processes, comprising: a chamber body; a lid assembly attached to the chamber body; a first gas delivery sub-assembly coupled to the lid assembly and configured for a cyclical layer deposition process, comprising: a gas conduit positioned on and extending through the lid assembly and having an expanding channel in fluid communication with the chamber body; a first gas inlet and a second gas inlet positioned on the gas conduit to form a circular gas flow pattern within the gas conduit; and a first high speed actuating valve coupled to the first gas inlet, a second high speed actuating valve coupled to the second gas inlet and the first and second high speed actuating valves are configured to sequentially pulse a first gas and a second gas during the cyclical layer deposition process; and a second gas delivery sub-assembly coupled to the lid assembly and configured for a chemical vapor deposition process, comprising: an annular mixing channel in fluid communication with the gas conduit and adapted to deliver a continuous flow of one or more compounds into the gas conduit during the chemical vapor deposition process.
