An ARC evaporator comprising: a cathode assembly comprising a cooling plate (11), a target (1) as cathode element, an electrode arranged for enabling that an arc between the electrode and the front surface (1A) of the target (1) can be established—a magnetic guidance system placed in front of the back surface (1 B) of the target (i) comprising means for generating one or more magnetic whereas: —the borders of the cathode assembly comprise a surrounding shield (15) made of ferromagnetic material, wherein the surrounding shield (15) has a total height (H) in the transversal direction, said total height (H) including a component (C) for causing a shielding effect of magnetic field lines extending in any longitudinal directions, establishing in this manner the borders of the cathode assembly as limit of the extension of the magnetic field lines in any longitudinal direction.
Tuneable uniformity control utilizing rotational magnetic housing
Embodiments described herein provide magnetic and electromagnetic housing systems and a method for controlling the properties of plasma generated in a process volume of a process chamber to affect deposition properties of a film. In one embodiment, the method includes rotation of the rotational magnetic housing about a center axis of the process volume to create dynamic magnetic fields. The magnetic fields modify the shape of the plasma, concentration of ions and radicals, and movement of concentration of ions and radicals to control the density profile of the plasma. Controlling the density profile of the plasma tunes the uniformity and properties of a deposited or etched film.
PLASMA UNIFORMITY CONTROL USING A PULSED MAGNETIC FIELD
In some implementations, a method for performing a plasma process in a chamber is provided, including: supplying a process gas to the chamber; applying pulsed RF power to the process gas in the chamber, the pulsed RF power being provided at a predefined frequency, wherein the applying of the pulsed RF power to the process gas generates a plasma in the chamber; during the applying of the RF power, applying a pulsed DC current to a magnetic coil that is disposed over the chamber, wherein the pulsed DC current is provided at the predefined frequency.
Multiple frequency electron cyclotron resonance thruster
An electron cyclotron resonance (ECR) thruster includes a magnetic field source configured to generate a magnetic field, a thruster body that defines a chamber, the thruster body being disposed relative to the magnetic field source such that the magnetic field is present in the chamber and such that a magnetic nozzle is established, an antenna configured to propagate radio frequency (RF) power within the chamber, and a waveform generator coupled to the antenna to generate an RF waveform for the RF power.

METHOD OF MANUFACTURING CRYSTALLINE MATERIAL FROM DIFFERENT MATERIALS
A method of manufacturing a crystalline layer of material on a surface, the crystalline layer including lithium, at least one transition metal and at least one counter-ion. The method includes the following steps: generating a plasma using a remote plasma generator, plasma sputtering material from a first target including lithium onto a surface of or supported by a substrate, there being at least a first plume corresponding to trajectories of particles from the first target onto the surface, and plasma sputtering material from a second target including at least one transition metal onto the surface, there being at least a second plume corresponding to trajectories of particles from the second target onto the surface. The first target is positioned to be non-parallel with the second target, the first plume and the second plume converge at a region proximate to the surface of or supported by the substrate, and the crystalline layer is formed on the surface at the region.
