Title:
METHOD FOR MANUFACTURING ACTIVE MATRIX SUBSTRATE AND METHOD FOR MANUFACTURING ORGANIC EL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/158840
Kind Code:
A1
Abstract:
In the gate electrode forming step according to the present invention, a metal film to be a gate electrode (18) of a TFT (7) is formed on a gate insulating film (17) covering an island-shaped semiconductor layer 16, the gate electrode (18) is formed by dry-etching the metal film, and plasma treatment using oxygen or nitrogen is performed with respect to the exposed gate electrode (18). Consequently, a needle crystal or a granular crystal is prevented from being formed, while suppressing deterioration of production efficiency.
