THIN FILMS OF NICKEL-COPPER BINARY OXYNITRIDE (NICUOxNy) AND THE CONDITIONS FOR THE PRODUCTION THEREOF
Thin films of nickel-copper binary oxynitride (NiCuO.sub.xN.sub.y) were deposited on the surface of AISI 3161 stainless steel and glass substrates using reactive phase RF sputtering with a thickness between 700 and 2100 nm under different deposition conditions from a bimetallic precursor target of nickel and copper under specific conditions, such as: base pressure, working pressure, argon flow, oxygen flow, nitrogen flow, power the NiCu precursor target, target-substrate distance and deposition time. The films were characterized and made it possible to carry out a preliminary study of biocompatibility and a characterization according to their optical properties
Physical vapor deposition in-chamber electro-magnet
A PVD chamber deposits a film with high thickness uniformity. The PVD chamber includes a coil of an electromagnetic that, when energized with direct current power, can modify plasma in an edge portion of the processing region of the PVD chamber. The coil is disposed within the vacuum-containing portion of the PVD chamber and outside a processing region of the PVD chamber.
Methods and apparatus for shutter disk assembly detection
Methods and apparatus for detecting a shutter disk assembly in a process chamber using a number of sensors. A first, second, and third sensor in a shutter housing for a shutter disk assembly provide indications of a status of the shutter disk assembly. The indications are used in part to determine the operational status of the shutter disk assembly along with process information from a process controller. The operational status is then used to alter a process of the process chamber when necessary.
BIASABLE FLUX OPTIMIZER / COLLIMATOR FOR PVD SPUTTER CHAMBER
A collimator that is biasable is provided. The ability to bias the collimator allows control of the electric field through which the sputter species pass. In some implementations of the present disclosure, a collimator that has a high effective aspect ratio while maintaining a low aspect ratio along the periphery of the collimator of the hexagonal array of the collimator is provided. In some implementations, a collimator with a steep entry edge in the hexagonal array is provided. It has been found that use of a steep entry edge in the collimator reduces deposition overhang and clogging of the cells of the hexagonal array. These various features lead to improve film uniformity and extend the life of the collimator and process kit.
