  • Patent number: 9017933
    Abstract: A method for treating a dielectric film on a substrate and, in particular, a method for integrating a low-k dielectric film with subsequently formed metal interconnects is described. The method includes preparing a dielectric film on a substrate, wherein the dielectric film is a low-k dielectric film having a dielectric constant less than or equal to a value of about 4. Thereafter, the method further includes performing a preliminary curing process on the dielectric film, forming a pattern in the dielectric film using a lithographic process and an etching process, removing undesired residues from the substrate, and performing a final curing process on the dielectric film, wherein the final curing process includes irradiating the substrate with ultraviolet (UV) radiation.

  • Patent number: 8824828
    Abstract: A method of fusing two images includes adjusting contrast of (a) a visual image and (b) a thermal image. Also included is modifying the adjusted contrast of the thermal image to form output brightness levels, by using a transformation curve, and then displaying both (a) the brightness levels of the thermal image and (b) the adjusted contrast of the visual image. Modifying the adjusted contrast of the thermal image includes using a V-curve as the transformation curve, in which the V-curve includes similar maximum output brightness levels at the coldest and hottest relative temperatures, respectively. The V-curve also includes a minimum output brightness level at a midpoint between the coldest and hottest relative temperatures. Furthermore, the method assigns different hues to the intensity values of the thermal image, ranging from coldest to hottest relative temperatures.

  • Patent number: 8530117
    Abstract: The present invention involves a method for making a relief image. A film that includes a carrier sheet and an imageable material is used to form a mask image that is opaque to a curing radiation. In one embodiment, the mask image is formed on the carrier sheet while in another embodiment, the mask image is formed on a receptor sheet. The mask image is then transferred to a photosensitive material, such as a flexographic printing plate precursor. The resulting assembly is exposed to the curing radiation resulting in exposed and unexposed areas of the photosensitive material. The carrier sheet or the receptor sheet may be removed from the mask image either before or after exposure to the curing radiation. Finally, the photosensitive material and mask image assembly is developed with a suitable developer to form a relief image.
