  • Patent number: 7020306
    Abstract: The object of the present invention is to establish a technology for directly evaluating polishing pad surface conditions, to allow high-precision CMP process management, and to improve process throughput. The pad surface is illuminated with light. The intensity of reflected light or fluorescence from the illuminated area or an intensity distribution image is used directly evaluate the pad surface condition. Based on the results of this evaluation, conditioning conditions for a conditioner are optimized, thus allowing high-precision CMP processing while maintaining good pad surface conditions.

  • Patent number: 4840487
    Abstract: An apparatus for measuring dry etching pits formed in a semiconductor device during the manufacture thereof by employing optical means. Wiring on semiconductor devices increasingly become fine or minute, i.e., the size of wiring of some devices is less than 1 .mu.m. A technical matter to be solved is to effect highly accurate dimensional measurement in such submicron region. The apparatus has a .theta. stage which is additionally provided on an XY stage, and a mechanism which provides excellent selectivity in detection of interference intensity of diffracted beam. In addition, a short wavelength laser, such as a He-Ne, He-Cd, N.sub.2 or Ar laser, is employed as a laser source. As a practical advantage, it is possible to monitor etching of a pit with a depth on the order of 10 .mu.m with respect to a pattern with a planar dimension of 0.3 .mu.m to 1.0 .mu.m.

  • Patent number: 4744660
    Abstract: An apparatus for measuring a difference in level in a sample comprises a light source section which provides illumination light of a variable-wavelength. The illumination light is irradiated onto the sample. A group of filters is provided for shielding diffraction light rays of O-order or other than O-order of the light reflected from the sample. The intensity of interference light of the light rays not shielded by the filter group is detected by a light detector which in turn converts it into an electric signal. An arithmetic operation unit receives the electric signal while the wavelength of the illumination light from the light source section is continuously varied. In the arithmetic unit, wavelengths at which the electric signal or detected light intensity takes extreme values are determined, and the level difference in the sample is determined on the basis of those wavelengths.

  • Patent number: 4721553
    Abstract: Disclosed herein are apparatuses of several types for forming a film at an increased rate that is necessary for putting the microwave assisting sputtering into practice on an industrial scale. The feature resides in that a plasma is maintained uniformly on the whole surface of target composed of a material to be sputtered. This makes it possible to avoid the target from being thermally destroyed by the increased energy of sputtering. Further, in order to prevent damage on a substrate on which the film is to be sputtered by plasma for sputtering, consideration is given to the arrangement of magnetic devices in order to form the film by positively introducing the plasma onto the substrate on which the film is to be formed and, at the same time, effecting the sputtering.

  • Patent number: 4675096
    Abstract: A continuous sputtering apparatus comprising a main vacuum chamber, one loading station and a plurality of process stations capable of having their pressures controlled separately. The process station includes a sub vacuum chamber capable of being in communication with the main vacuum chamber through an opening and an evacuation port. The loading station and the process stations are arranged to be spaced with equal angles. Substrate holders are provided to face the stations and are rotated by said equal angle in a time. The substrate holder opens and closes the opening of the sub vacuum chamber to serve as a gate valve.

  • Patent number: 4628531
    Abstract: A pattern checking apparatus carries out the detection of candidate defects through a primary selection with a sensitivity high enough to detect any existing defect, and then carries out a detailed analysis by a controlling processor for a pattern including the periphery of the detected candidate defect through a secondary selection in which a candidate defect which is not a defect in a practical sense is removed from candidates, so that only real defects are detected.

  • Patent number: 4615620
    Abstract: An apparatus for measuring in a non-contact manner the depth of pits and grooves formed by etching in periodic patterns on the surface of a substrate. The measurement is based on the detection of the intensity of a diffraction ray excluding that of the 0th order through the irradiation of a light beam with variable wave length to the sample. Whereas, the conventional measuring system is sensitive to a diffraction ray of the 0th order, i.e., the major component of the reflected light, that hampers the detection of a higher order diffraction ray carrying information of the depth.

  • Patent number: 4610770
    Abstract: A pair of magnets for producing a mirror magnetic field are disposed outside of an electrode structure carrying a target. Microwaves from a microwave source are introduced toward and into a space defined by the mirror magnetic field for generating high-density plasma. While maintaining this high-density plasma over a wide area of the surface of the target, an electric field substantially perpendicular to the surface of the target is applied for sputtering of the target material. The optimized conditions for plasma generation can be selected when the high-density plasma formed outside of a processing chamber is guided to migrate toward an area above the target in the processing chamber. Capability of sputtering of the material from the entire surface of the target increases the rate of film deposition on a substrate and improves the target utilization rate (the quantity of the material deposited on the substrate/the usable area of the target).

  • Patent number: 4487678
    Abstract: The invention is directed to a dry-etching apparatus used for etching an aluminum wiring film formed on a wafer, and more particularly to a dry-etching apparatus which can remove chlorides deposited on the surface of the wafer during the dry etching thereof, as well as an etching resist film, without having to take the wafer out. This dry-etching apparatus is provided with an etching chamber, a vacuum antechamber attached to the etching chamber by a gate valve, and a post-treatment chamber attached to the vacuum antechamber. The apparatus is so formed that etched wafers removed to the vacuum antechamber can be sent therefrom to the post-treatment chamber, and then the post-treated wafers can be removed to the vacuum antechamber again, and then removed therefrom to the atmosphere.
