Thin film transistor, method of manufacturing the same and flat panel display device having the same
ActiveUS8148779B2Improve featuresAvoid chargingSolid-state devicesSemiconductor/solid-state device manufacturingTrappingEngineering
A thin film transistor (TFT) using an oxide semiconductor as an active layer, a method of manufacturing the TFT, and a flat panel display device having the TFT include a gate electrode formed on a substrate; an active layer made of an oxide semiconductor and insulated from the gate electrode by a gate insulating layer; source and drain electrodes coupled to the active layer; and an interfacial stability layer formed on one or both surfaces of the active layer. In the TFT, the interfacial stability layer is formed of an oxide having a band gap of 3.0 to 8.0 eV. Since the interfacial stability layer has the same characteristic as a gate insulating layer and a passivation layer, chemically high interface stability is maintained. Since the interfacial stability layer has a band gap equal to or greater than that of the active layer, charge trapping is physically prevented.

Disclosed are a semiconductor device and a manufacturing method thereof. According to the semiconductor device and the manufacturing method thereof according to exemplary embodiments of the present invention, after the dopant source layer is uniformly deposited on a channel layer of the device with the 3-demensional vertical structure by the plasma-enhanced atomic layer deposition (PEALD) method, the deposited dopant source layer is heat-treated so that the dopants are diffused into the channel layer to function as charge carriers, thereby preventing the charges in the channel layer from being reduced. According to the exemplary embodiments of the present invention, the diffusion speed and concentration of the dopant may be controlled by forming the barrier layer between the channel layer and the dopant source layer.
