  • Publication number: 20080131822
    Abstract: A template, stamp or mold is fabricated by using a low-k material. The structure of the low-k material is transformed when it is baked in a novel heating process. Thus, the template is fabricated to obtain a high hardness and a high aspect-ratio with a low dose of electron beam lithography and an optimized baking process. Consequently, the residual; layer at photoresist bottom is reduced and the time for reactive ion etching is saved. In the end, the stability and the integrity is improved. Hence, the present invention is a solution for fabricating a template, stamp or mold with the feature size from sub-micrometer down to nanometer level.

  • Patent number: 5622816
    Abstract: A method and apparatus for creating an optical disk mother or stamper wherein the number of processing steps is greatly reduced from the prior art methods. In particular, the present invention involves directly forming a mother or stamper by direct laser ablation of a conductive metal substrate. More specifically, a stream of coded digital information (for example, representing the content of an encyclopedia in the case of CD ROM or a classical music collection in the case of CD audio) is converted into a corresponding plurality of pits and lands in the conductive metal substrate by electronically switching the beam of a first laser on and off via an electro or acusto-optic modulator (EOM/AOM) in response to the digital information. As a result, selective portions of the conductive substrate are either ablated (in the case where the laser is on) thereby directly creating the pits, or the substrate is left unaltered (in the case where the laser is off) thereby creating lands.

  • Patent number: 5518844
    Abstract: In a first processing step, whether a first photosensitive material is a particular photosensitive material is detected. If it is detected at least that the first photosensitive material is the particular photosensitive material, processing conditions in the first processing step are recorded in a predetermined position on the first photosensitive material. Exposure conditions in the exposure step are set in accordance with one of the result of the detection and the processing conditions recorded on the first photosensitive material. The second photosensitive material is exposed under the set exposure conditions. If the first photosensitive material is detected to be a particular photosensitive material, the setting of the exposure conditions is changed in the exposure step, and the exposure conditions are set in such a manner as to compensate the difference in the characteristic occurring in the image of the particular first photosensitive material depending on standard processing and particular processing.

  • Patent number: 5397686
    Abstract: A method for temporarily marking a surface whose distance from a light beam source can substantially vary, without requiring focusing or refocusing of the light beam, commences with the step of coating a portion of the surface with a light reactant, color-forming chemical solution. The solution is soluble in a liquid solvent that is nonreactive with the surface. The coated portion of the surface is exposed to a collimated, non-focused laser beam exhibiting an airy disk pattern having central bright spot, the exposure occurring for a period of time that enables the central bright spot to expose the coating and to manifest a color change at points of incidence. The bright spot exhibits a diameter that does not exceed a predetermined diameter within an expected distance variations between the source of the laser beam and the surface.
