    摘要: Fabrication of a polysilicon TFT having a lightly doped drain or offset structure. Fabrication includes forming a semiconductor layer, a gate insulating film, and a gate electrode on a substrate. Then, forming lightly doped impurity regions in the semiconductor layer on both sides of the gate electrode. Next, forming an insulating film having a thickness that gradually becomes thinner away from the gate electrode. Then, forming heavily doped impurity regions in the lightly doped impurity regions in the semiconductor layer on both sides of the gate, resulting in regions with continuously varied impurity concentrations.

    摘要: A TFT type optical detecting sensor includes a sensor TFT for generating optical current by detecting light reflected from an object, a storage capacitor for storing charges of the optical current, and a switching TFT for controlling releasing of the charges stored in the storage capacitor. The storage capacitor is made of a transparent conductive material, such that light is transmitted from a light source through the storage capacitor to the object.
