1. A semiconductor circuit having a capacitor and a thin film transistor (TFT), the substrate comprising:

  • a substrate;

    a semiconductor layer and a first capacitor electrode formed on the substrate, the first capacitor electrode being doped to be conductive;

    an insulating layer covering the semiconductor layer and the first capacitor electrode;

    a gate electrode disposed on the insulating layer and corresponding to a portion of the semiconductor layer; and

    a second capacitor electrode disposed on the insulating layer and corresponding to the first capacitor electrode,wherein the gate electrode is thicker than the second capacitor electrode.
