Array substrates and the manufacturing method thereof, and display panels of enhanced speed of film formation

摘要

The present disclosure relates to an array substrate and the manufacturing method thereof, and a display panel. The array substrate includes a substrate and a plurality of thin film transistors (TFTs). The TFT includes a gate, a gate insulation layer, a trench layer, an etch stop layer (ESL), a source, and a drain. The gate insulation layer is arranged between the gate and the trench layer to insulate the gate from the trench layer, the source. The drain and the ESL are respectively arranged on the trench layer. The ESL is arranged between the source and the drain. The ESL is an aluminum nitride (AlN) film. In this way, the quality of the TFTs may be guaranteed, and the speed of the film formation of the ESL may be enhanced.

主权项

1. A manufacturing method of array substrates of enhancing speed of film formation, comprising:
forming a gate, a gate insulation layer, and a trench layer on a substrate, wherein the gate insulation layer being arranged between the gate and the trench layer; and forming an ESL, a source and a drain on the trench layer, the ESL being arranged between the source and the drain, wherein the ESL is AlN film, and applying a sputtering process by a magnetron sputtering device to form the AlN film on the trench layer, wherein an AL chamber is filled with hydrogen or mixed gas of argon and hydrogen.
