The method includes providing an arc-vaporization source with at least one electric solenoid and a permanent magnet arrangement including marginal permanent magnets and a central permanent magnet. The method further includes adjusting the position of the central and marginal permanent magnets relative to the target surface in at least three settings, adjusting the strength of the generated magnetic field based on the position of the central and marginal permanent magnets among the at least three settings, and coating the substrates by an ARC vaporization coating process performed by the ARC vaporization source at each of the at least three settings.
HYBRID ION SOURCE FOR ALUMINUM ION GENERATION USING A TARGET HOLDER AND A SOLID TARGET
An ion source that is capable of different modes of operation is disclosed. The ion source includes an insertable target holder includes a hollow interior into which the solid dopant material is disposed. The target holder may a porous surface at a first end, through which vapors from the solid dopant material may enter the arc chamber. The porous surface inhibits the passage of liquid or molten dopant material into the arc chamber. The target holder is also constructed such that it may be refilled with dopant material when the dopant material within the hollow interior has been consumed. A solid target is also disposed in the arc chamber. When the insertable target holder is used, multicharged ions are created. When the insertable target holder is retracted, single charged ions are created by only etching the solid dopant-containing compound.
HYBRID ION SOURCE FOR ALUMINUM ION GENERATION USING A TARGET HOLDER AND ORGANOALUMINIUM COMPOUNDS
An ion source that is capable of different modes of operation is disclosed. The ion source includes an insertable target holder includes a hollow interior into which the solid dopant material is disposed. The target holder may a porous surface at a first end, through which vapors from the solid dopant material may enter the arc chamber. The porous surface inhibits the passage of liquid or molten dopant material into the arc chamber. The target holder is also constructed such that it may be refilled with dopant material when the dopant material within the hollow interior has been consumed. The ion source may have several gas inlets. When the insertable target holder is used, the ion source may supply a first gas, such as a halogen containing gas. When operating in a second mode, the ion source may utilize an organoaluminium gas.
Deposition apparatus
A deposition apparatus, which forms a film on a substrate, includes a rotation unit configured to rotate a target about a rotating axis; a striker configured to generate an arc discharge; a driving unit configured to drive the striker so as to make a close state which the striker closes to a side surface around the rotating axis of the target to generate the arc discharge; and a control unit configured to control rotation of the target by the rotation unit so as to change a facing position on the side surface of the target facing the striker in the close state.
Fluorine ion implantation system with non-tungsten materials and methods of using
A system and method for fluorine ion implantation is described, which includes a fluorine gas source used to generate a fluorine ion species for implantation to a subject, and an arc chamber that includes one or more non-tungsten materials (graphite, carbide, fluoride, nitride, oxide, ceramic). The system minimizes formation of tungsten fluoride during system operation, thereby extending source life and promoting improved system performance. Further, the system can include a hydrogen and/or hydride gas source, and these gases can be used along with the fluorine gas to improve source lifetime and/or beam current.
ION GENERATOR AND ION IMPLANTER
An ion generator includes an arc chamber defining a plasma generation space, and a cathode which emits thermoelectrons toward the plasma generation space. The arc chamber includes a box-shaped main body having an opening, and a slit member mounted to cover the opening and provided with a front slit. An inner surface of the main body is exposed to the plasma generation space made of a refractory metal material. The slit member includes an inner member made of graphite and an outer member made of another refractory metal material. The outer member includes an outer surface exposed to an outside of the arc chamber. The inner member includes an inner surface exposed to the plasma generation space, and an opening portion which forms the front slit extending from the inner surface of the inner member to the outer surface of the outer member.
Device and Process for the Production of Hydrogen and Solid Carbon From C1- to C4-Alkane Containing Gas
The present invention concerns a device for the production of hydrogen and solid carbon from C.sub.1 to C.sub.4-alkane-containing gas by means of thermal plasma, a process for the production of hydrogen and solid carbon from C.sub.1 to C.sub.4-alkane-containing gas by means of thermal plasma, and the use of a device in a process for the production of hydrogen and solid carbon from C.sub.1 to C.sub.4-alkane-containing gas by means of a process of the invention.
HIGH POWER ELECTROSTATIC CHUCK WITH FEATURES PREVENTING HE HOLE LIGHT-UP/ARCING
A spark suppression apparatus for a helium line in an electrostatic chuck in a plasma processing chamber is provided. The spark suppression apparatus comprises a dielectric multilumen plug in the helium line, wherein the dielectric multilumen plug has a plurality of lumens, wherein the plurality of lumens are numbered between 30 to 100,000 lumens and have a width of between 1 micron and 200 microns.
Mask structure and FCVA apparatus
Embodiments of the present disclosure provide a mask structure and a filtered cathodic vacuum arc (FCVA) apparatus. The mask structure is configured to prepare protrusions on a carrying surface of an electrostatic chuck and includes a main mask plate and a side mask plate that are made of a conductive metal. The main mask plate is configured to form a patterned film layer corresponding to the protrusions on the carrying surface of the electrostatic chuck. The side mask is configured to cover a side surface of the electrostatic chuck to avoid forming a film layer on the side surface. The mask structure can be electrically conductive. The mask structure may prevent the side surface of the electrostatic chuck from being coated when the protrusions are prepared on the carrying surface of the electrostatic chuck. Thus, the mask structure may be applied to an FCVA process.
Insertable target holder for solid dopant materials
An ion source with an insertable target holder for holding a solid dopant material is disclosed. The insertable target holder includes a pocket or cavity into which the solid dopant material is disposed. When the solid dopant material melts, it remains contained within the pocket, thus not damaging or degrading the arc chamber. Additionally, the target holder can be moved from one or more positions where the pocket is at least partially in the arc chamber to one or more positions where the pocket is entirely outside the arc chamber. In certain embodiments, a sleeve may be used to cover at least a portion of the open top of the pocket.
