摘要： A CVD apparatus is equipped with a reactor, a substrate holder, an evacuation section, a reactive gas supply mechanism, a heating mechanism for heating the substrate holder, a differential pressure chuck clamping section for clamping the substrate, and a purge gas supply mechanism for supplying purge gas. The substrate holder is configured to have a circular purge gas blowing channel on the top surface thereof, in which a diameter of an outside wall-surface is less than a diameter of the substrate, and a plurality of purge gas passages in an inside thereof, each of which supplies the purge gas into the purge gas blowing channel. The purge gas passing the purge gas blowing channel is blown off through a clearance between the outer periphery of the substrate and the substrate holder. The purge gas passage includes a radius-directed part directed in a radius direction of the substrate holder and has a purge gas outlet provided on the outside wall-surface of the purge gas blowing channel. The flow of the purge gas in a circumferential direction within the purge gas blowing channel is turbulent and dispersed, and therefore the purge gas blow-off pressure in the whole periphery of the substrate is uniform.

摘要： This invention discloses ionization sputtering apparatuses which have a function for ionizing sputtered particles. Those apparatuses comprise an ionization means for ionizing sputtered particles from a target. The ionization means generates a plasma by applying radio frequency energy with plasma generation gas at an ionization space between the target and a holder holding a substrate. An disclosed apparatus comprises a magnetic device preventing the plasma from diffusing from the ionization space. Another disclosed apparatus comprises a magnetic device which orients the ionized sputtered particles toward the substrate.
