  • Patent number: 10078263
    Abstract: A method of forming a pattern comprises diffusing an acid formed by irradiating a portion of a photosensitive layer, into an underlayer comprising an acid sensitive copolymer having acid decomposable groups and attachment groups covalently bonded to the surface of the substrate and/or forming an interpolymer crosslink. Diffusing comprises heating the underlayer and photosensitive layer. The acid sensitive group reacts with the diffused acid to form a polar region on the underlayer, with the shape of the pattern. The photosensitive layer is removed, forming a self-assembling layer comprising a block copolymer having a first block with an affinity for the polar region, and a second block having less affinity for the polar region. The first block forms a domain aligned to the polar region, and the second block forms another domain aligned to the first. Removing either domain exposes a portion of the underlayer.

  • Publication number: 20180224741
    Abstract: A photoimageable composition for preparing a polymeric binder having of one or more of monomer unit copolymers, a photoactive compound, and one or more organometallic compounds is provided. The copolymers include one or more hydroxyl or carboxyl functional groups that react with the organometallic compound to form a crosslinked network upon curing. The photoimageable compositions may be particularly useful in forming a pixel-defining layer of an electronic device. such as an organic light emitting diode. In particular, photoimageable compositions in accordance with embodiments of the present invention are insoluble in the developer prior to exposure to radiation, soluble in the developer following radiation exposure, and have relatively high glass transition temperatures (Tg) making them useful in forming a pixel-defining layer.
