20090032511Apparatus and method of improving beam shaping and beam homogenization - The present invention generally relates to an optical system that is able to reliably deliver a uniform amount of energy across an anneal region contained on a surface of a substrate. The optical system is adapted to deliver, or project, a uniform amount of energy having a desired two-dimensional shape on a desired region on the surface of the substrate. Typically, the anneal regions may be square or rectangular in shape. Generally, the optical system and methods of the present invention are used to preferentially anneal one or more regions found within the anneal regions by delivering enough energy to cause the one or more regions to re-melt and solidify.02-05-2009
20090034071METHOD FOR PARTITIONING AND INCOHERENTLY SUMMING A COHERENT BEAM - A method and apparatus for decorrelating coherent light from a light source, such as a pulsed laser, in both time and space in an effort to provide intense and uniform illumination are provided. For some embodiments employing a pulsed light source, the output pulse may be stretched relative to the input pulse width. The methods and apparatus described herein may be incorporated into any application where intense, uniform illumination is desired, such as pulsed laser annealing, welding, ablating, and wafer stepper illuminating.02-05-2009
20090034072METHOD AND APPARATUS FOR DECORRELATION OF SPATIALLY AND TEMPORALLY COHERENT LIGHT - A method and apparatus for decorrelating coherent light from a light source, such as a pulsed laser, in both time and space in an effort to provide intense and uniform illumination are provided. The techniques and apparatus described herein may be incorporated into any application where intense, uniform illumination is desired, such as pulsed laser annealing, welding, ablating, and wafer stepper illuminating.02-05-2009
20090037868AREA BASED OPTICAL PROXIMITY CORRECTION IN RASTER SCAN PRINTING - Methods and apparatus for correcting defects, such as rounded corners and line end shortening, in patterns formed via lithography are provided. Such defects are compensated for “post-rasterization” by manipulating the grayscale values of pixel maps.02-05-2009
20100266268Multi-stage Optical Homogenization - Substrate processing equipment and methods are used to improve the uniformity of illumination across an illuminated portion of a substrate by processing light with multiple optical homogenizers. The multiple optical homogenizers each include micro-lens arrays and Fourier lens. The multiple optical homogenizers are arranged so that the output numerical aperture of one of the optical homogenizers is within 5% of the input numerical aperture of another optical homogenizer.10-21-2010

20100247822VARIABLE DEPTH LASER SCORED EASY-OPEN POUCH FOR MICROWAVE STEAM VENTING - A multilayer film includes at least an abuse layer that is laser scored, and a sealant layer that has discrete weakened portions, due to the laser scoring. The multilayer film may have a tensile strength of between about 0.40 and 2.5 pounds per 10 millimeters at the location of the one or more weakened portions. In certain aspects, the tensile strength of the multilayer film is between about 7 and 14 pounds per inch at the location of the laser scoring on the abuse layer. Also, a package is provided that is formed from one or more multilayer films having a scored abuse layer and a sealant layer with weakened portions that allow steam and/or pressure to be vented from the package during heating. Optionally, the abuse layer includes a shallow scoring portion to provide an easy-open feature. For instance, the package may be used to cook frozen foods contained in the package, such as in a microwave oven.09-30-2010
