  • Non-Volatile Ferroelectric Thin Film Device Using an Organic Ambipolar Semiconductor and Method for Processing Such a Device
    Publication number: 20070252137
    Abstract: A non-volatile ferroelectric memory device is proposed which comprises a combination of an organic ferroelectric polymer with an organic ambipolar semiconductor. The devices of the present invention are compatible with—and fully exploit the benefits of polymers, i.e. solution processing, low-cost, low temperature layer deposition and compatibility with flexible substrates.

  • METHOD OF MANUFACTURING A REPLICA AS WELL AS A REPLICA OBTAINED BY CARRYING OUT AN UV LIGHT-INITIATED CATIONIC POLYMERIZATION
    Publication number: 20070132947
    Abstract: The invention relates to a method of manufacturing a replica, which method comprises the provision of a polymerizable resin composition between a front mold having a pre-shaped surface and a back mold having a pre-shaped surface, carrying out a curing treatment and removing the replica thus manufactured from the molds. The invention further relates to a replica obtained by carrying out a UV light-initiated cationic polymerization.

  • Content information layer for an optical record carrier
    Publication number: 20060204751
    Abstract: An optical record carrier (2) and associated methods and devices are described. The carrier (2) comprises at least one user information layer (4a,4b) arranged to be scanned by first radiation, and at least one content information layer (3a,3b) or label layer. The content information layer comprises representing content information and having a first transmission for said first radiation and a second, lower transmission for a different, second radiation.

  • Method of manufacturing a flexible electronic device and flexible device
    Publication number: 20060194363
    Abstract: An electrical element, such as a thin-film transistor, is defined on a flexible substrate, in that the substrate is attached to a carrier by an adhesive layer, and is delaminated after definition of the transistor. This is for instance due to illumination by UV-radiation. An opaque coating is provided to protect any semiconductor material. A heat treatment is preferably given before application of the layers of the transistor to reduce stress in the adhesive layer.

  • Photo-sensitive composition
    Publication number: 20050089791
    Abstract: The invention pertains to a photo-sensitive composition which comprises a photochemical initiator, a polyacid or a salt thereof, and a poly(3,4-alkylenedioxythiophene) wherein the alkylene moiety is —(CH2)n- , n being an integer from 1 to 3, or 1,2-cyclo-hexylene, which may optionally be substituted, characterized in that the photochemical initiator is a water-soluble polymer comprising at least two azide or diazonium groups. Preferably, the water-soluble polymer is chemically stable at pH 6 or less, more preferably at pH 2 or less.
