摘要:
Methods of depositing and curing a dielectric material on a substrate are described. The methods may include the steps of providing a processing chamber partitioned into a first plasma region and a second plasma region, and delivering the substrate to the processing chamber, where the substrate occupies a portion of the second plasma region. The methods may further include forming a first plasma in the first plasma region, where the first plasma does not directly contact with the substrate, and depositing the dielectric material on the substrate to form a dielectric layer. One or more reactants excited by the first plasma are used in the deposition of the dielectric material. The methods may additional include curing the dielectric layer by forming a second plasma in the second plasma region, where one or more carbon-containing species is removed from the dielectric layer.

A method of making an electrostatic chuck comprising positioning a plate into a channel in a body to form a plenum and inserting a dielectric component into an opening in the plate, where the dielectric component defines a portion of a passage from the plenum. Thereafter, depositing a dielectric layer covering at least a portion of the body and at least a portion of the plate to form a support surface. The dielectric layer is polished to a specified thickness. In one embodiment, the polishing process forms an opening through the dielectric layer to enable the dielectric component to define a passage between the support surface and the plenum. In another embodiment, at least a portion of the dielectric layer is porous proximate the dielectric component such that the porous dielectric layer and the dielectric component form a passage between the support surface and the plenum. In a further embodiment, a hole is formed through the dielectric layer and the hole in the dielectric layer and the dielectric component form a passage between the support surface and the plenum.

A method and apparatus for providing a fluid distribution element for an electrostatic chuck that reduces plasma formation and arcing within heat transfer fluid passages. One embodiment comprises a plate and a dielectric component, where the dielectric component is inserted into the plate. The plate is adapted to be positioned within a channel to define a plenum, wherein the dielectric component provides at least a portion of a fluid passage coupled to the plenum. A porous dielectric layer, formed upon the dielectric component, provides at least another portion of a fluid passage coupled to the plenum. In other embodiments, the fluid distribution element comprises various arrangements of components to define a fluid passage that does not provide a line-of-sight path from the support surface for a substrate to a plenum.

Embodiments of the invention provide methods for forming conductive materials within contact features on a substrate by depositing a seed layer within a feature and subsequently filling the feature with a copper-containing material during an electroless deposition process. In one example, a copper electroless deposition solution contains levelers to form convexed or concaved copper surfaces. In another example, a seed layer is selectively deposited on the bottom surface of the aperture while leaving the sidewalls substantially free of the seed material during a collimated PVD process. In another example, the seed layer is conformably deposited by a PVD process and subsequently, a portion of the seed layer and the underlayer are plasma etched to expose an underlying contact surface. In another example, a ruthenium seed layer is formed on an exposed contact surface by an ALD process utilizing the chemical precursor ruthenium tetroxide.

摘要:
An apparatus and a method of controlling an electroless deposition process by directing electromagnetic radiation towards the surface of a substrate and detecting the change in intensity of the electromagnetic radiation at one or more wavelengths reflected off features on the surface of the substrate is provided. In one embodiment, the detected end of an electroless deposition process step is measured while the substrate is rotated relative to the detection mechanism. In another embodiment, a detection mechanism, which is proximate to the processing region, directs electromagnetic radiation onto a substrate surface, which is then reflected by features on the substrate surface and is detected by the detection mechanism. In one aspect, the angle of the directed electromagnetic radiation is perpendicular to the surface of the substrate and the shape of the directed electromagnetic radiation spot is substantially circular in shape. In another aspect, the directed electromagnetic radiation spot is positioned at the center of rotation of the substrate. A controller can be used to monitor, store, and/or control the electroless deposition process by use of stored process values, comparison of data collected at different times, and various calculated time dependent data.

A lifting mechanism includes a plurality of lift pins which may be driven separately and independently upward to engage an alignment surface of the chamber using ambient atmospheric pressure as the chamber is evacuated by a pump. In the illustrated embodiment, each lift pin includes a piston which is exposed to the internal chamber pressure on one side of the piston, and is exposed to the external ambient pressure on the other side of the piston. As the pump evacuates the chamber, the internal chamber pressure decreases, causing each lift pin piston to drive the associated lift pin upward. Once all the lift pins have securely engaged the alignment surface, the lift pins may be clamped to a linking mechanism to permit a motor to actuate the lift pins during processing operations.
