Granted: 1999-09-11
Abstract: During electronic film development, an area of conventional photographic film us scanned several times using a single scanning station, and at each subsequent time this scanned area is advanced incrementally along the film with multiple levels of overlap with previous scans. The new image scanned at each new time is aligned to an accumulating image that has been extrapolated to the image at the new time, and then the new image is added to the accumulating image in parametric summations that allow an image to be interpolated to any time free of seams where the scans overlap. The invention further teaches a method of steering the alignment by warping the leading edge of the alignment, and a registration method of alignment multiple images that takes advantage of known fixed alignments between images.

If the thickness is within the tolerance range, the semiconductor wafer is taken out of the polisher and placed in the rinsing and spin-drying process. If the thickness is not within the tolerance range, then it should be determined if the thickness of the polished layer is less than the minimum of the tolerance range. If the thickness of the polished layer is less than the minimum value of the tolerance range, then it is placed in the rinsing and spin-drying process and taken from the chemical mechanical polisher. If the thickness of the polished layer is larger than the minimum value of the tolerance and is not within the tolerance range, then the chemical mechanical polishing process for the semiconductor wafer is repeated.
