Chain scission resist compositions suitable for EUV lithography applications may include monomer functional groups that improve the kinetics and/or thermodynamics of the scission mechanism. Chain scission resists may include monomer functional groups that reduce the risk that leaving groups generated through the scission mechanism may chemically corrode processing equipment.

WHITE-LIGHT HYPERBRANCHED CONJUGATED POLYMER, METHOD FOR PREPARING THE SAME AND IT'S USE

This application discloses a white-light hyperbranched conjugated polymer, a method for preparing the same and its use. The polymer uses a red phosphorescent Ir(III) complex as a core and polyfluorene derivative blue fluorescent materials as a framework which either contains or does not contain carbazole derivatives, and the white light hyperbranched polymers realize white-light emission by adjusting the content of the red phosphorescent Ir(III) complex connected using the complementation of blue and red color.
