Abstract

The invention discloses a thin film transistor and a manufacturing method thereof. The semiconductor layer material of the thin film transistor is a cross-linked nano-particle film formed through carrying out crosslinking treatment on a nanoparticle film. The cross-linked nano-particle film is applied in the semiconductor layer of the thin film transistor so that a hot carrier effect can be effectively reduced and the performance of the thin film transistor is greatly increased.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a thin film transistor and a preparation method thereof. Background technique [0002] A thin film transistor (thin film transistor, TFT), as a switching element, is widely used in electronic devices such as liquid crystal displays. [0003] In the process of preparing thin film transistors by solution method, oxide nanoparticles are one of the important solutions to form the corresponding oxide film, mainly because oxide nanoparticles (or spherical oxide nanocrystals) have good crystallinity, which ensures On the other hand, due to the good self-assembly of oxide nanoparticles into films, low-cost coating preparation processes can be applied. Common oxide nanoparticles include zinc oxide (ZnO x ) nanoparticles, titanium oxide (TiO x ) nanoparticles, etc., the nanoparticle film is usually used in the semiconductor layer of the thin film transistor. [0004] Nevertheless,...
