A plasma system includes a plasma device, an ionizable media source, and a power source. The plasma device includes an inner electrode and an outer electrode coaxially disposed around the inner electrode. The inner electrode includes a distal portion and an insulative layer that covers at least a portion of the inner electrode. The ionizable media source is coupled to the plasma device and is configured to supply ionizable media thereto. The power source is coupled to the inner and outer electrodes, and is configured to ignite the ionizable media at the plasma device to form a plasma effluent having an electron sheath layer about the exposed distal portion.

Examples of a jet control device are described. The jet control device can comprise a jet deflecting member that is configured to intercept and/or collide with a high speed jet emerging from a jet formation location. The interaction of the jet deflecting member and the jet can cause the high speed jet to be dispersed into a plurality of jets with a number of flow directions which may be sideways to an initial direction of the high speed jet. In one embodiment the deflecting member can include a liquid guide formed by injecting a fluid out of an outlet nozzle so that the liquid guide extends longitudinally away from the outlet nozzle. In another embodiment the deflecting member can include an array of solid pellets injected through an outlet in a direction of the emerging high speed jet and configured to collide with the emerging jet thereby deflecting its initial direction.

Energy output from a laser-produced plasma (LPP) extreme ultraviolet light (EUV) system varies based on how well the laser beam is focused on droplets of target material to generate plasma at a primary focal spot. Maintaining droplets at the primary focal spot during burst firing is difficult because generated plasma from preceding droplets push succeeding droplets out of the primary focal spot. Current droplet-to-droplet feedback control to re-align droplets to the primary focal spot is relatively slow. The system and method described herein adaptively pre-compensate for droplet push-out by directing droplets to a target position that is offset from the primary focal spot such that when a droplet is lased, the droplet is pushed by the laser beam into the primary focal spot to generate plasma. Over time, the EUV system learns to maintain real-time alignment of droplet position so plasma is generated consistently within the primary focal spot.

An ionic wind engine unit for cooling semiconductor circuit assemblies includes a curved micro-spring and an associated electrode that are maintained apart at an appropriate gap distance such that, when subjected to a sufficiently high voltage potential (i.e., as determined by Peek's Law), current crowding at the spring's tip portion creates an electrical field that sufficiently ionizes neutral molecules in a portion of the air-filled region surrounding the tip portion to generate a micro-plasma event. In one engine type the electrode is a metal pad, and in a second engine type the electrode is a second micro-spring. Ionic wind cooling is generated, for example, between an IC die and a base substrate in a flip-chip arrangement, by controlling multiple engines disposed on the facing surfaces to produce an air current in the air gap region separating the IC device and base substrate.

The disclosed plasma CVD apparatus (1) is provided with a vacuum chamber (3); a pair of deposition rollers (2, 2) disposed within the vacuum chamber (3) that are connected to both poles of an AC power supply and around which a substrate (W) is wound; a gas-supplying device (5) that supplies process gas containing a source gas to a deposition zone (D) which is a portion of or all of the region that is on one side of a line linking the centers of rotation of the pair of deposition rollers (2, 2); and a magnetic-field-generating device (7) that, by means of the AC power supply being applied to each of the deposition rollers (2, 2), forms a magnetic field that causes the source gas in a predetermined region to become plasma. The magnetic-field-generating device (7) causes the source gas in the region adjacent to the surface of the portion of the pair of deposition rollers (2, 2) located within the deposition zone (D) to become plasma, forming a plasma region (P). The substrate (W) is wound around the pair of deposition rollers (2, 2) so as to pass through the plasma region (P).

Embodiments of the present disclosure provide apparatus and methods for improving plasma uniformity around edge regions and/or reducing non-symmetry in a plasma processing chamber. One embodiment of the present disclosure provides a plasma tuning assembly having one or more conductive bodies disposed around an edge region of a substrate support in a plasma processing chamber. The one or more conductive bodies are isolated from other chamber components and electrically floating in the processing chamber near the edge region without connecting to active electrical potentials. During operation, when a plasma is maintained in the plasma processing chamber, the presence of the one or more conductive bodies affects the plasma distribution near the one or more conductive bodies.

A plasma generation apparatus includes a vacuum container, dielectrics connected to through-holes formed in the vacuum container, RF coils of the same structure disposed in the vicinity of the respective dielectrics and electrically connected in parallel, an RF power source to supply power to the RF coils, an impedance matching circuit disposed between the RF power source and the RF coils, and a power distribution unit disposed between the impedance matching circuit and one ends of the RF coils to distribute the power of the RF power source to the RF coils. The power distribution unit includes a power distribution line and a conductive outer cover enclosing the power distribution line. Distance between an input end of the power distribution unit and the RF coils are equal to each other, and the other ends of the RF coils are connected to the conductive outer cover to be grounded.

A method for generating hydrogen plasma includes a step for preparing a solution in which hydrogenated hydrogen with ion binding properties or ortho hydrogen molecules have been dissolved. The method also includes exposing the solution to ultrasonic waves or microwaves. Preferably, microbubbles are agitated by projecting ultrasonic waves or microwaves as solar energy, generating hydrogen plasma when the microbubbles burst.
