Title:
THIN FILM TRANSISTOR AND MANUFACTURING METHOD THEREFOR, ARRAY SUBSTRATE, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/134380
Kind Code:
A1
Abstract:
Provided are a thin film transistor and a manufacturing method therefor, an array substrate, and a display device. The thin film transistor comprises: a substrate; a channel region; a heavily-doped first semiconductor pattern, positioned on two sides of the channel region; a second semiconductor pattern, provided on the heavily-doped first semiconductor pattern; a gate insulating layer, covering the channel region and the second semiconductor pattern; a gate pattern, provided on the gate insulating layer, orthographic projection of the gate pattern on the substrate being positioned in a range of the orthographic projection of the channel region on the substrate; and a source pattern and a drain pattern, being in contact with the heavily-doped first semiconductor pattern by means of a first via hole and a second via hole, respectively.
