  • Patent number: 10690847
    Abstract: The invention is based on the idea of providing a light emitting diode (OLED) device which contains a substrate with a photonic crystal, whereby the formed film structure induces enhancement of the liberation of photons trapped inside the light emitting device structure. The photonic crystal structure is a film structure on a substrate produced using a combination of high and low refractive index materials, at least one of the materials being based on a liquid phase deposited metal-oxide or metalloid oxide material. By means of the invention light trapped due to total internal reflection in a waveguide acting light emitting structure can be extracted efficiently from the device by introducing the photonic crystal device structure between the substrate and conductive anode layer.

  • Patent number: 9284455
    Abstract: An organic-inorganic composition, which has a backbone containing —Si—O— units with chromophore groups attached directly to at least a part of the silicon atoms. The film forming composition and resulting coating properties can be tailored to suit the specific exposure wavelength and device fabrication and design requirements. By using two different chromophores the refractive index and the absorption co-efficient can be efficiently tuned and a desired Si-content of the anti-reflective coating composition can be obtained—a high Si-content will give good mechanical and thermal properties and also the required wet etch and dry etch properties.

  • Patent number: 9273209
    Abstract: A siloxane composition and a method of producing the same. The composition comprises a siloxane prepolymer with a backbone exhibiting a group which is capable of being deprotonated in an aqueous base solution. Further, there are reactive functional groups, which are capable of reacting during thermal or radiation initiated curing. The siloxane is cross-linked during condensation polymerization to increase molecular weight thereof. The composition can be used in high-resolution negative tone lithographic fabrication processes where a water based developer system is applied in the development step of the lithography process.

  • Patent number: 9062229
    Abstract: Process for producing an organosiloxane polymer and novel organosiloxane polymer compositions. The process according to the invention comprises hydrolyzing tetraalkoxysilane monomers in a hydrolysis step; and polymerising said hydrolyzed monomers in a polymerization step by subjecting them to conditions conducive to polymerisation to form an organosiloxane polymer. The hydrolysis step is conducted in a reaction medium comprising an organic compound with hydroxy groups. The invention allows for the synthesis of siloxane polymer compositions suitable for thin-film applications using a high content of tetra- and trifunctional silixane polymer precursors.
