Movement systems for sputter coating of non-flat substrates
A movement system is provided for moving a non-flat substrate across a sputter flux distribution without circumferentially exposing the non-flat substrate to the sputter flux distribution. The movement system is arranged for a first movement of translationally transporting the non-flat substrate along the sputter flux distribution, and a second movement of translating and/or rotating the non-flat substrate with respect to the sputter flux distribution.
FILM FORMING APPARATUS
A film forming apparatus includes: a rotary table provided in a chamber; a processing unit configured to perform plasma processing on a workpiece transferred by the rotary table; an inner wall configured to define a processing space and having an opening facing the rotary table; an outer wall configured to cover a periphery of the inner wall with a gap, and configured to form an exhaust space having an opening facing the rotary table; and an exhaust port connected to an exhaust device, wherein the processing unit is a film forming part configured to form a film by sputtering, and wherein both ends of the outer wall are in contact with a side surface of the chamber, and a portion of an outer periphery of the inner wall and the side surface of the chamber are partitioned, so that a reaction gas does not circulate in the exhaust space.
Defect control in RF plasma substrate processing systems using DC bias voltage during movement of substrates
A substrate processing system includes a processing chamber and an upper electrode arranged in the processing chamber. A pedestal is configured to support a substrate during processing and includes a lower electrode. An RF generating system is configured to generate RF plasma between the upper electrode and the lower electrode by supplying an RF voltage. A bias generating circuit is configured to selectively supply a DC bias voltage to one of the upper electrode and the lower electrode. A start of the DC bias voltage is initiated one of a first predetermined period before the RF plasma is extinguished and a second predetermined period after the RF plasma is extinguished. A substrate movement system is configured to move the substrate relative to the pedestal while the DC bias voltage is generated.
DROP-ON-DEMAND IDENTIFICATION DOCUMENT PRINTING WITH SURFACE PRE-TREATMENT
A single plasma nozzle of a plasma treatment station is used to treat the card surface prior to performing drop-on-demand printing on the card surface. The single plasma nozzle has a plasma discharge width that is less than the width of the card. The card and the plasma nozzle are moved relative to one another using a two direction control scheme during plasma treatment in order to be able to plasma treat a desired area of the card surface. The card and the plasma nozzle may also be moveable toward or away from one another to change the distance therebetween.
System and method for mitigating oxide growth in a gate dielectric
Oxide growth of a gate dielectric layer that occurs between processes used in the fabrication of a gate dielectric structure can be reduced. The reduction in oxide growth can be achieved by maintaining the gate dielectric layer in an ambient effective to mitigate oxide growth of the gate dielectric layer between at least two sequential process steps used in the fabrication the gate dielectric structure. Maintaining the gate dielectric layer in an ambient effective to mitigate oxide growth also improves the uniformity of nitrogen implanted in the gate dielectric.
FILM DEPOSITION METHOD AND FILM DEPOSITION APPARATUS
A film deposition method is provided for filling a recessed pattern formed in a surface of a substrate with a film. In the method, an adsorption blocking group is formed by adsorbing chlorine gas activated by plasma on a top surface of the substrate and an upper portion of the recessed pattern. A source gas that contains one of silicon and a metal, and chlorine, is adsorbed on a lower portion of the recessed pattern where the adsorption blocking group is not formed, by supplying the source gas to the surface of the substrate including the recessed pattern. A molecular layer of a nitride film produced by a reaction of the source gas and a nitriding gas is deposited on the lower portion of the trench by supplying the nitriding gas to the surface of the substrate including the recessed pattern.
