  • Method of performing an operation with rheological compound
    Patent number: 8025542
    Abstract: An apparatus includes integrated review, material removal and material deposition functions. The apparatus performs the review, material removal and material deposition operations along the same optical axis. The apparatus includes, in part, a camera, a pair of lenses, and one or more lasers. A first lens is used to focus the camera along the optical axis on a structure formed on the target substrate undergoing review. The first lens is also used to focus the laser beam on the structure to remove a material present thereon if the reviewed structure is identified as requiring material removal. The second lens is used to focus the laser beam on a ribbon to transfer a rheological compound from a recessed well formed in the ribbon to the structure if the reviewed structure is identified as requiring material deposition.

  • Laser ablation using multiple wavelengths
    Patent number: 7977602
    Abstract: In laser micromachining and laser defect repair of a first material, a first set of one or more laser wavelengths is selected in accordance with the first material's absorption characteristics and is combined and delivered concurrently with a second set of one or more laser wavelengths which is selected in accordance with the absorption characteristics of a second material generated by and remaining from the ablating interaction of the first material with the first set of laser wavelengths. The concurrent presence of the second set of one or more laser wavelengths removes the residual second material.
