Patent ID: 7335584

Claim:
A method of using SACVD deposition to deposit at least one layer of dielectric material inside a deposition reactor during the fabrication of at least one semiconductor integrated circuit, said method comprising the steps of: providing a reaction chamber for carrying out SACVD deposition; supplying a stream of a first reaction gas containing oxygen plasma into a first gas feed conduit connected to the reaction chamber; applying microwaves inside the first gas feed conduit in order to produce sufficient oxygen radicals from the oxygen plasma, the oxygen radicals being necessary to initiate SACVD deposition; supplying a stream of a second reaction gas into the reaction chamber through a second gas feed conduit, the second reaction gas being suitable to initiate SACVD deposition when reacting with oxygen radicals; and supplying the first reaction gas, in which sufficient oxygen radicals have been produced from oxygen plasma, from the first gas feed conduit into the reaction chamber to perform an SACVD deposition within the reaction chamber through reaction of oxygen radicals with the second reaction gas.
