Problems solved by technology

However, since metal oxides are extremely susceptible to the doping effect of impurities such as mobile metal ions, hydrogen ions, and oxygen vacancies, an etch barrier structure with channel protection is usually used, and it is difficult to use a top gate structure

Abstract

The embodiment of the invention discloses a thin film transistor, a display panel and a manufacturing method of the thin film transistor. The thin film transistor comprises: an active layer arranged on the surface of a glass substrate, and a source electrode and a drain electrode connected to the active layer; a first insulating layer arranged on a side of the active layer away from the glass substrate; a gate layer arranged on the first The insulating layer is away from the side of the glass substrate; the second insulating layer covers the source, drain and gate layers, and the second insulating layer is provided with through holes, which expose the source and drain; the material used in the active layer is (MO)x(RO)y(TO)z, where 0

Description

technical field [0001] Embodiments of the present invention relate to semiconductor technology, and in particular, to thin film transistors, display panels, and manufacturing methods of thin film transistors. Background technique [0002] The core technology of the new flat panel display industry is thin film transistor (TFT, Thin Film Transistor) backplane technology. Metal oxide TFT (MO-TFT, Metal Oxide-TFT) not only has high mobility (at 1-100cm 2 / (V*s) or so), and the manufacturing process is relatively simple, compatible with the current a-Si process, the manufacturing cost is low, and it also has excellent large-area uniformity. Therefore, MO-TFT technology has attracted the attention of the industry since its birth. However, since metal oxides are extremely susceptible to the doping effect of impurities such as mobile metal ions, hydrogen ions, and oxygen vacancies, an etch barrier structure with channel protection is usually used, and it is difficult to use a top ...
