  • Method and composition for reducing waste in photo-imaging applications
    Publication number: 20080286450
    Abstract: Waste reduction, including hazardous waste reduction in photoimaging processes can be accomplished by improving diffusional resolution of cationic curable compositions. The addition of fluorinated polymers including fluorinated surfactants provides improved diffusional resolution in cationic and/or radical based photoimaging formulations allowing for image accuracy improvements, and reduced product and process waste quantity and disposal cost. These fluorinated surfactants also allow for increased cure speed, and non-hazardous constituent formulations that result in less wasted material and time.
    Type: Application
    Filed: January 26, 2007
    Publication date: November 20, 2008
    Applicant: DSM IP Assets B.V.
    Inventors: John Lawton, Jigeng Xu, John Southwell, Gordon Smith, Willem Weenink
  • Contacts to microdevices
    Publication number: 20070070311
    Abstract: Provided are microdevices, e.g. integrated circuits, with contact bumps and processes for making the same. The microdevices may have contact bumps on two or more sides of the microdevices. Also provided are stacks of microdevices.
