Patent ID: 8859929

Claim:
An apparatus for depositing a film on a substrate from a plasma comprising: an enclosure, a plurality of plasma generator elements disposed within the enclosure, and means, also within the enclosure, for supporting the substrate, each plasma generator element comprising: a microwave antenna having an end from which microwaves are emitted, a magnet disposed in the region of the said antenna end and defining therewith an electron cyclotron resonance region in which a plasma can be generated by distributed electron cyclotron resonance (DECR), and at least one gas entry element having an outlet for a film precursor gas or a plasma gas, the outlet being arranged to direct gas towards (as defined herein) a film deposition area which is situated beyond the magnet, as considered from the microwave antenna, the outlet being located above the ends of the magnets nearest the film deposition area, and thus being located in, or above, the hot electron confinement envelope, as defined herein.
