Film-forming apparatus, film-forming system, and film-forming method
A film-forming apparatus comprises: a processing chamber defining a processing space, a first sputter-particle emitter and a second sputter-particle emitter having targets, respectively, from which sputter-particles are emitted in different oblique directions in the processing space, a sputter-particle blocking plate having a passage hole through which the sputter particles emitted from the first sputter-particle emitter and the second sputter-particle emitter pass, a substrate support configured to support a substrate and provided at a side opposite the first sputter-particle emitter and the second sputter-particle emitter with respect to the sputter-particle blocking plate in the processing space, a substrate moving mechanism configured to linearly move the substrate supported on the substrate support, and a controller configured to control the emission of sputter-particles from the first sputter-particle emitter and the second sputter-particle emitter while controlling the substrate moving mechanism to move the substrate linearly.
Shield for a substrate processing chamber
A shield encircles a sputtering target that faces a substrate support in a substrate processing chamber. The shield comprises an outer band having a diameter sized to encircle the sputtering target, the outer band having upper and bottom ends, and the upper end having a tapered surface extending radially outwardly and adjacent to the sputtering target. A base plate extends radially inward from the bottom end of the outer band. An inner band joined to the base plate at least partially surrounds a peripheral edge of a substrate support. The shield can also have a heat exchanger comprising a conduit with an inlet and outlet to flow heat exchange fluid therethrough.

Method for heating a wide bandgap substrate by providing a resistive heating element which emits radiative heat in a mid-infrared band
Methods and systems of heating a substrate in a vacuum deposition process include a resistive heater having a resistive heating element. Radiative heat emitted from the resistive heating element has a wavelength in a mid-infrared band from 5 μm to 40 μm that corresponds to a phonon absorption band of the substrate. The substrate comprises a wide bandgap semiconducting material and has an uncoated surface and a deposition surface opposite the uncoated surface. The resistive heater and the substrate are positioned in a vacuum deposition chamber. The uncoated surface of the substrate is spaced apart from and faces the resistive heater. The uncoated surface of the substrate is directly heated by absorbing the radiative heat.

SUBSTRATE PROCESSING APPARATUS
A substrate processing apparatus includes a processing chamber configured to process a substrate by using a processing gas; a rotary table that is rotatably provided in the processing chamber; a stage on which the substrate is to be placed and that is configured to be rotatable relative to the rotary table at a position spaced apart from a center of rotation of the rotary table, a lift pin configured to be displaced relative to the stage to raise and lower the substrate; and a housing configured to house the lift pin when the lift pin is not unexposed from the stage. The lift pin and the housing have a closing structure that closes a gap between the lift pin and the housing.
Apparatus and methods for depositing durable optical coatings
Apparatus for depositing germanium and carbon onto one or more substrates comprises a vacuum chamber, at least first and second magnetron sputtering devices and at least one movable mount for supporting the one or more substrates within the vacuum chamber. The first magnetron sputtering device is configured to sputter germanium towards the at least one mount from a first sputtering target comprising germanium, thereby defining a germanium sputtering zone within the vacuum chamber.
