Abstract:
1. A CMOS thin film transistor, comprising: an active channel of a P-type thin film transistor, the active channel being formed in polycrystalline silicon, an active channel of a N-type thin film transistor, the active channel being formed in polycrystalline silicon, primary grain boundaries in the P-type thin film transistor, primary grain boundaries in the N-type thin film transistor, wherein a direction of the active channel of the P-type transistor is different from a direction of the active channel of the N-type transistor such that the primary grain boundaries of the P-type thin film transistor are at an angle of about 60° to about 120° with respect to the active channel direction of the P-type thin film transistor and the primary grain boundaries of the N-type thin film transistor are out an angle of about −30° to about 30° with respect to the active channel direction of the N-type thin film transistor.
