Abstract
SLS crystallization and CMOS LTPS process have been developed for high performance and uniform characteristics. By strictly optimizing SLS optics in conventional 2 shot SLS process, threshold voltage variation of 720 pixel TFTs in 2.2-inch QVGA panel (240×RGB) was remarkably decreased from 1.89 V to 0.56 V of 3sigma value. Mobility of the channel doped NTFT and PTFT for circuits were 146 and 38 cm2/Vs, respectively. Functional unit circuits for SOG were also fabricated and properly operated.
