  • Method for producing micromachined devices and devices obtained thereof
    Patent number: 6740542
    Abstract: The present invention is related to a method for producing micromachined devices for use in Microelectromechanical Systems (MEMS), comprising the steps of providing a crystalline wafer, and processing from said wafer at least one micromachined device comprising at least one elongated opening and/or cavity, having a longitudinal axis, so that said longitudinal axis is at an angle to a direction which lies along the intersection of the front plane of the wafer and a cleavage plane, said cleavage plane being defined as a plane along which cleavage of the wafer is most likely to occur.
    Type: Grant
    Filed: October 9, 2001
    Date of Patent: May 25, 2004
    Assignees: Interuniversitair Microelektronica Centrum, Eastman Kodak Company

  • Method for making lithographic printing plates according to the silver salt diffusion transfer process
    Patent number: 6130023
    Abstract: The present invention provides a method for making an offset printing plate according to the silver salt diffusion transfer process comprising the steps of: (a) image-wise exposing an imaging element comprising (i) a hydrophilic base, (ii) an image receiving layer containing physical development nuclei, (iii) an intermediate layer, and (iv) a silver halide emulsion layer,(b) applying an aqueous alkaline solution to the imaging element in the presence of (a) developing agent(s) and (a) silver halide solvent(s) to form image-wise in said image receiving layer a silver image,(c) treating the imaging element to remove the layer(s) on top of said image receiving layer,characterized in that said imaging element has been stored before image-wise exposure in a surrounding having at 22.degree. C. a relative humidity between 20% and 50%.According to the present invention there is also provided a package of the imaging element, making said imaging element suitable for use in the above defined method.
