    摘要: A gas in a vacuum plasma processing chamber is ignited to a plasma by subjecting the gas to an r.f. field derived from an r.f. source having a frequency and power level sufficient to ignite the gas into the plasma and to maintain the plasma. The r.f. field is supplied to the gas by a reactive impedance element connected via a matching network to the r.f. source. The matching network includes first and second variable reactances that control loading of the source and tuning a load, including the reactive impedance element and the plasma, to the source. The value of only one of the reactances is varied until a local maximum of a function of power coupled between the source and the load is reached. The value of only the other reactance is varied until a local maximum of the function is reached. The two varying steps are then repeated as necessary.

    摘要: Silicon dioxide on a substrate is directionally etched using a hydrogen halide plasma which is created within an etch chamber. The method selectively etches silicon dioxide relative to polysilicon and silicon nitride. A substrate and the combination of NH.sub.3 and NF.sub.3 gases or the combination of CF.sub.4 and O.sub.2 gases mixed with H.sub.2 and N.sub.2 gases are located within an etch chamber. An electrical field is created within the etch chamber causing the gas mixture to form a plasma. The negative charge at the bottom of the chamber attracts the positively charged plasma, thereby etching the substrate in the downward direction. The result is an anisotropic product. The method is also shown to be effective in non-selectively etching thermal and deposited oxides, resulting in a similar etch rate for the different types of oxides.

    摘要: Apparatus and methods for plasma processing involving the gettering of particles having a high charge to mass ratio away from a semiconductor wafer are disclosed. In one aspect of the invention, magnets are used to produce a magnetic field which is transverse to an electric field to draw the negative particles away from the wafer to prevent the formation of a sheath which can trap the particles. In a second aspect of the invention, a power source is connected to the wafer electrode to maintain a negative charge on the wafer, thereby preventing negative particles from being drawn to the wafer surface when the plasma is turned off. In other embodiments of the invention, a low density plasma source is used to produce a large plasma sheath which permits particles to cross a chamber to be gettered. A low density plasma discharge followed by a pulse to a higher density is used to overcome the negative effect of an insulating layer between the wafer and the wafer electrode.

    摘要: Apparatus and methods are provided that enable processing of patterned layers on substrates using a detachable mask. Unlike prior art where the mask is formed directly over the substrate, according to aspects of the invention the mask is made independently of the substrate. During use, the mask is positioned in close proximity or in contact with the substrate so as to expose only portions of the substrate to processing, e.g., sputtering or etch. Once the processing is completed, the mask is moved away from the substrate and may be used for another substrate. The substrate may be cycled for a given number of substrates and then be removed for cleaning or disposal.

    摘要: Lubricant coatings are applied as vapor to magnetic disks. The method and apparatus include applying vaporizing heat to a pre-determined amount of liquid to form a vapor. Precision delivery of lubricant vapor allows close-loop lube thickness control. The flow of the liquid to the heater is controlled such that only a pre-determined amount from the reservoir flows to the heater at a time, the pre-determined amount is vaporized. According to an aspect, the pre-determined amount of liquid is transferred from the reservoir for the application of vaporizing heat; isolating the reservoir from the vacuum of the vacuum chamber. The method enables multiple types of lubricants to be applied to the disk. Another heater is included for applying vaporizing heat to a second liquid to form a second vapor to supply to the disk. According to an aspect, pulsed lubricant vapor delivery is provided, conserving lubricant and minimizing thermal decomposition.

    摘要: An arrangement for concurrently powering a plurality of sputtering sources. A power supply is coupled to a charge accumulator. The charge accumulator is coupled to several sputtering sources via switching devices. The duty cycle of each switching device is used to individually control the power delivered to each sputtering source. In another arrangement, a power source is coupled to an impedance match circuit. The impedance match circuit is coupled to several sputtering sources via several balance elements. Each balance element is operated to individually control the power delivered to the sputtering source.
