  • Patent number: 8288683
    Abstract: A dynamic surface anneal apparatus for annealing a semiconductor workpiece has a workpiece support for supporting a workpiece, an optical source and scanning apparatus for scanning the optical source and the workpiece support relative to one another along a fast axis. The optical source includes an array of laser emitters arranged generally in successive rows of the emitters, the rows being transverse to the fast axis. Plural collimating lenslets overlie respective ones of the rows of emitters and provide collimation along the fast axis. The selected lenslets have one or a succession of optical deflection angles corresponding to beam deflections along the fast axis for respective rows of emitters. Optics focus light from the array of laser emitters onto a surface of the workpiece to form a succession of line beams transverse to the fast axis spaced along the fast axis in accordance with the succession of deflection angles.

  • Patent number: 8110828
    Abstract: A method of manufacturing a semiconductor layer is provided. In a first deposition during a first period of time, at least one Group IIIA element and at least one Group VIA element are deposited on a substrate or on a layer optional disposed on the substrate such as a back-electrode. During a second deposition during a second period of time, at least one Group IB element and the at least one group VIA element are deposited on the substrate or the optional layer. The one Group IB element combines with the Group VIA element to form a IB2VIA composition. A first deposition state is monitored, during the second deposition by making a first plurality of measurements of a first deposition state. The second deposition is terminated or attenuated based on a function of the first plurality of measurements of the indicia of the first deposition state.
