摘要: A process for measuring the alignment of different layers on a semiconductor wafer (33) includes forming repetitive alignment marks (14, 24) having substantially the same period on the different layers on the wafer (33). The images of the overlay alignment marks (14, 24) are converted from space domain to frequency domain through Fourier transformations. The alignment measurements are performed by calculating the phase difference between the images corresponding to the repetitive patterns (14, 24) on different layers.

摘要: Improved CMP uniformity is achieved by providing improved control of the slurry distribution. Improved slurry distribution is achieved by, for example, the use of a slurry dispenser that dispenses slurry from a plurality of dispensing points. Providing a squeeze bar between the slurry dispenser and wafer to redistribute the slurry also improves the slurry distribution.

摘要: In a method for electrically contacting thin-film solar modules interconnected in integrated fashion, a number of solar cells forming a module are created by structuring a layer on a substrate to produce strip-shaped, side-by-side solar cells, and electrically conductive contact strips are laid over the electrode layers of the two outermost, individual solar cells. The conductive strips are held in place by a lamination using hot-melt adhesive foil at elevated pressure and temperature, in the same step wherein a backing is laminated with the solar module. If necessary, the contact strips can be attached by an electrically conductive paste or utilizing an ultrasonic welding process.
