  • Patent number: 10983434
    Abstract: Provided is a photoresist composition including a plasma light absorber and a method of manufacturing semiconductor devices using the same. The photoresist composition may include a developable polymer, a photoacid generator, a plasma light absorber, and an organic solvent. The plasma light absorber may be relatively transmissive to light used with a photolithographic patterning process (e.g., ultraviolet light) to pattern a layer formed with the photoresist composition and be relatively absorptive to light created in a subsequent etching process (such as light generated from a plasma). When forming a semiconductor device, a patterned photoresist layer may be more precisely generated and may better maintain is desired properties when used to etch various target layers of the semiconductor device.

  • Patent number: 9753431
    Abstract: The present invention provides a visible light photoinitiating system for preparing a holographic photopolymer material with high-diffraction efficiency. The photoinitiating system comprises a photosensitizer and a co-initiator, and its mechanism is that the photosensitizer transforms from ground state to excited state after absorbing photons, and then interacts with the co-initiator through transfer of electrons and protons, which produces an alkyl (or aryl) free radical R and a ketyl radical K; wherein the free radical R initiates the addition polymerization of monomers that are capable of free radical polymerization, whereas the radical K inhibits the chain propagation of the macromolecular free radicals to a certain degree due to the steric hindrance effect, and thus delays the gelation time of the photopolymerization, which helps to increase the phase separation between the polymer and the functional components.

  • Patent number: 7838570
    Abstract: An ink used preferably in jet ink devices includes an ink vehicle, the ink vehicle being made up either (a) a first component curable by a first polymerization route and an associated photointiator, and a second component curable by a second polymerization route and as associated photoinitiator, wherein the second polymerization route is different from the first polymerization route, or (b) a component curable by a single polymerization route with a first and a second photoinitiator system in which the first system responds to longer wavelengths. An image may be formed by such inks by jetting onto a transfer member surface, curing the first component or partially curing the single component while upon the transfer member surface, transferring the ink to an image receiving surface, and completing curing. The first component is preferably curable via cationic polymerization and the second component is preferably curable via free radical polymerization.
