  • Patent number: 8821682
    Abstract: Systems and methods of imaging and repairing defects on and below the surface of an integrated circuit (IC) are described. The method may be used in areas as small as one micron in diameter, and may remove the topmost material in the small spot, repeating with various layers, until a desired depth is obtained. An energetic beam, such as an electron beam, is directed at a selected surface location. The surface has an added layer of a solid, fluid or gaseous reactive material, such as a directed stream of a fluorocarbon, and the energetic beam disassociates the reactive material in the region of the beam into radicals that chemically attack the surface. After the defect location is exposed, the method uses the energetic beam to etch undesired materials, and deposit various appropriate materials to fill gaps, and restore the IC to an operational condition.

  • Patent number: 8809074
    Abstract: A method provides a mechanism to examine physical properties and/or diagnose problems at a selected location of an integrated circuit. Such a method can include creating a layer of a reactive material a selected distance above and in proximity with a surface of the integrated circuit so that the reactive material can be evaluated to form chemical radicals above and in proximity to the surface of the integrated circuit. A portion of the reactive material can be excited. A portion of the surface of the integrated circuit can be removed to a selected level to evaluate an exposed electrical structure of the integrated circuit. The exposed electrical structure can be evaluated to determine a potential problem in the integrated circuit.

  • Patent number: 8609542
    Abstract: Methods may operate to position a sample within a processing chamber and operate on a surface of the sample. Further activities may include creating a layer of reactive material in proximity with the surface, and exciting a portion of the layer of reactive material in proximity with the surface to form chemical radicals. Additional activities may include removing a portion of the material in proximity to the excited portion of the surface to a predetermined level, and continuing the creating, exciting and removing actions until at least one of a plurality of stop criteria occurs.

  • Patent number: 8026501
    Abstract: A method that may be applied to imaging and identifying defects and contamination on the surface of an integrated circuit is described. An energetic beam, such as an electron beam, may be directed at a selected IC location having a layer of a solid, fluid, or gaseous reactive material formed over the surface. The energetic beam disassociates the reactive material in the region into chemical radicals that either chemically etch the surface preferentially, or deposit a thin layer of a conductive material over the local area around the energetic beam. The surface may be examined as various layers are selectively etched to decorate defects and/or as various layers are locally deposited in the area around the energetic beam. SEM imaging and other analytic methods may be used to identify the problem more easily.

  • Patent number: 7892978
    Abstract: A method of imaging and identifying materials, contamination, fabrication errors, and defects on and below the surface of an integrated circuit (IC) is described. The method may be used in areas smaller than one micron in diameter, and may remove IC layers, either selectively or non-selectively, until a desired depth is obtained. An energetic beam, such as an electron beam, is directed at a selected IC location. The IC has a layer of a solid, fluid or gaseous reactive material, such as a directed stream of a fluorocarbon, formed over the surface of the IC. The energetic beam disassociates the reactive material in or on the region into chemical radicals that chemically attack the surface. The surface may be examined as various layers are selectively removed in the controlled area spot etch, and SEM imaging may then be used to diagnose problems.

An energetic beam, such as an electron beam, is directed at a selected surface location. The surface has an added layer of a solid, fluid or gaseous reactive material, such as a directed stream of a fluorocarbon, and the energetic beam disassociates the reactive material in the region of the beam into radicals that chemically attack the surface. The reaction products from the radical attack on the surface are pumped away from the surface and analyzed using various methods, such as optical emission, infrared, atomic absorption, or Raman spectroscopy.
