Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 19:
20. The display panel of claim 18, wherein forming on the substrate the gate and the signal trace spaced apart from the gate comprises:
forming on the substrate a first metal layer to-be-processed;
forming on the first metal layer to-be-processed a photoresist layer to-be-processed;
exposing and developing the photoresist layer to-be-processed to form a photoresist layer;
etching the first metal layer to-be-processed to form a first metal layer, part of the first metal layer serving as the gate, and the rest of the first metal layer serving as the signal trace; and
removing the photoresist layer.
