There is provided a MTCMOS flip-flop configured to operate at high speed and to reduce leakage current while realizing a retention function in a sleep mode. The MTCMOS flip-flop may include a signal generator adapted to output an internal clock signal or a sleep mode control signal based on changes in a retention signal and an external clock signal, a master latch adapted to latch an input signal and to output a master latch output signal based on the internal clock signal, and a slave latch connected to an actual ground and adapted to latch the master latch signal, to output a slave latch output signal under control of the internal clock signal, and to maintain the latched signal under control of the sleep mode control signal in the sleep mode.

Disclosed herein is a photoresist composition which includes a norbornene copolymer having an epoxy group, an acid generator, and an organic solvent. The norbornene polymer shows superior mechanical and thermal properties, high transparency, excellent insulating properties, and particularly, improved mechanical properties due to the presence of an epoxy group. The photosensitive resin composition shows superior performance, e.g., transparence, developing properties, residual film characteristics, chemical resistance, heat resistance, and flatness. Particularly, since the photosensitive resin composition enables easy formation of a pattern as an interlayer insulating film and shows a high light transmittance even when being formed into a thin film with a relatively large thickness, it is suitable for the production of an interlayer insulating film used in the fabrication processes of LCDs.
