Abstract: A cathode arc source has means for generating first and second magnetic fields, of opposite or reverse direction to each other. The resultant magnetic field includes a null point between the target and the substrate, though close to the target. Field strength normal to the target is zero at the null point, and field strength lateral to the target is strong at the target surface, constraining movement of the arc spot and reducing the risk of migration off the target surface. A target is made by pressing graphite powder at elevated temperature and pressure in the absence of binding material. Both source and target contribute to reduced macroparticles in deposited films.

Abstract: A magnetron sputtering apparatus has a controller (10a) or selectively releasing the spread of plasma on a substrate (3) on a support (12). The controller can also contain the plasma when the substrate is to be coated with the target material. This enables cleaning of the target surface during intervals between deposition of target material onto a desired substrate, such as a wafer, and ensures that layers or flakes of back-scattered deposited target material do not build up on the target itself. A platen coil is located between the magnetron and the support to increase both uniformity and density of target material arriving nearly normal to the substrate surface.

Abstract: An electromagnetic field generator and method of operation for ion beam deposition of magnetic thin-film materials is presented. A combination of open frame electromagnetic field generator elements provides precise control of magnetic field directionality. This control enables deposition of oriented magnetic films with minimal directionality error. The magnetic field direction may be oriented to enable the deposition of alternating layers of directionally oriented magnetic films. An open frame element reduces the weight of the electromagnetic field generator while truncated corners reduce diagonal clearance that may be required in a vacuum chamber. An open frame design also enables the electromagnetic field generator to surround and thus remain clear of the active deposition area; the electromagnetic field generator can thus be shielded from accumulation of sputtered material. Shielding from accumulation of sputter material reduces maintenance requirements.

Abstract: Increased sidewall coverage by a sputtered material is achieved by generating an ionizing plasma in a relatively low pressure sputtering gas. By reducing the pressure of the sputtering gas, it is believed that the ionization rate of the deposition material passing through the plasma is correspondingly reduced which in turn is believed to increase the sidewall coverage by the underlayer. Although the ionization rate is decreased, sufficient bottom coverage of the by the material is maintained. In an alternative embodiment, increased sidewall coverage by the material may be achieved even in a high density plasma chamber by generating the high density plasma only during an initial portion of the material deposition. Once good bottom coverage has been achieved, the RF power to the coil generating the high density plasma may be turned off entirely and the remainder of the deposition conducted without the high density plasma.

Through the magnetic field component (6), the angular distribution of the ionized particles is deflected from its flight path perpendicular to the substrate surface, so that impact angles are produced that have a greater angular scattering.
