  • Patent number: 6030750
    Abstract: The present invention provides a method for making a lithographic printing plate comprising the steps of:(1) image-wise exposing to light an imaging element comprising (i) on a hydrophilic surface of a lithographic base an image forming layer comprising hydrophobic thermoplastic polymer particles capable of coalescing under the influence of heat and dispersed in a hydrophilic binder and (ii) a compound capable of converting light to heat, said compound being comprised in said image forming layer or a layer adjacent thereto;(2) and developing a thus obtained image-wise exposed imaging element by mounting it on a print cylinder of a printing press and supplying an aqueous dampening liquid and/or ink to said image forming layer while rotating said print cylinder.

  • Patent number: 6022672
    Abstract: A method, system or device for forming a resist pattern applied to fine processing, such as that for preparation of a semiconductor device. The wafer transportation system for the process affected by processing conditions of the process, such as the temperature or time, is provided independently of the wafer transportation system for other processes in order to prevent heat transmission through a transport arm to assure a more accurate resist forming operation and to control the wafer transportation time between the processes more accurately and promptly. Pattern formation may be achieved more accurately through the use of a chemical amplification resist material subject to influences from the wafer environment.
