Abstract:
The disclosure provides a manufacturing method for a thin film transistor, wherein a manufacturing method for a data line and a source/drain specifically includes: S21: respectively manufacturing a data line material film layer and a source/drain material film layer; S22: manufacturing a photoresist material film layer; S23: performing a half-tone method to etch the photoresist material film layer, forming a photoresist layer, and obtaining a first etching substrate; S24: performing a 4-mask process to etch the first substrate, forming the data line on a gate insulating layer, forming the source and the drain on an active layer, and forming a the back channel between the source and the drain to obtain the thin film transistor. The disclosure further provides a manufacturing method for an array substrate, wherein the manufacturing method for an array substrate includes the above-mentioned manufacturing method for a thin film transistor.

Claim (Index 11):
A manufacturing method for an array substrate, wherein at least comprises a manufacturing method for a thin film transistor; wherein the manufacturing method for a thin film transistor comprises the following steps:\n Q1: sequentially manufacturing a gate, a gate insulating layer and an active layer on a base; and Q2: manufacturing a data line on the gate insulating layer, manufacturing a source and a drain on the active layer, etching the active layer between the source and the drain to form a back channel, and obtaining a thin film transistor; wherein a specific method of the step Q2 comprises the following steps: Q21: manufacturing a data line material film layer on the gate insulating layer, manufacturing a source/drain material film layer on the active layer; Q22: manufacturing a photoresist material film layer on the data line material film layer and the source/drain material film layer; Q23: performing a half-tone mask method to etch the photoresist material film layer, forming a photoresist layer, and obtaining a first etching substrate; wherein a thickness of an edge of the photoresist layer on the data line material film layer is smaller than a thickness of a center of the photoresist layer on the data line material film layer, a width of the center of the photoresist layer on the data line material film layer is equal to a width of a pre-formed data line, a thickness of an edge of the photoresist layer on the source/drain material film layer and a thickness of a center of the photoresist layer on the source/drain material film layer are smaller than a thickness between the edge of the photoresist layer on the source/drain material film layer and the center of the photoresist layer on the source/drain material film layer, and a width from the center of the photoresist layer on the source/drain material film layer extending to the edge of the photoresist layer on the source/drain material film layer is equal to a width of an edge spacing between a pre-formed source and a pre-formed drain; and Q24: performing a 4-mask process to etch the first substrate, forming the data line on the gate insulating layer, forming the source and the drain on the active layer, and forming the back channel between the source and the drain to obtain the thin film transistor.
