Transistors are tiny electrical devices which can be used for amplification, switching, signal modulation, voltage stabilization and many other functions. Integrated circuit technology relies on transistors to formulate functional circuits. Transistors use an electric current or field voltage to amplify another electric current or field voltage, creating electronic pulses that can represent the ones and zeros of binary computing. Transistors are roughly classified into two types: a bipolar transistor that operates with actions of carriers of both an electron and a hole; and a unipolar transistor that operates with an action of a carrier of either an electron or a hole. A semiconductor transistor generally comprises a channel region and first and second source/drain (S/D) regions formed in a semiconductor layer. A typical transistor device comprises a transistor gate over El semiconductor substrate. The transistor gate comprises a conductive material, such as, for example, conductively doped polysilicon, and can further comprise metal silicide and/or metal over the conductively doped silicon. There are numerous applications for transistor devices in semiconductor constructions. For instance, transistor devices can be incorporated into logic, memory, processor and other integrated circuit devices. Thin film transistors (TFTs) are generally used as pixel drive elements. A TFT has an active layer comprised of a thin semiconductor film formed on an insulator substrate. Optical transistor technology could be utilized for optic fiber communication, optical switching and routing, and wavelength conversion.
