Abstract: PURPOSE: A method for manufacturing a thin film transistor having a rounded gate is provided to prevent the generation of hump because an edge part of a gate electrode is rounded by an undercut phenomenon. CONSTITUTION: A first conductive film is evaporated on an insulation board(10). After the first conductive film is dry-etched, a wet-etching process is implemented for a constant time to form a gate(26). A gate insulation layer(40) is formed on the gate and the board. A semiconductor material is evaporated on the gate insulation layer. A source section(52), a drain section(54), and a channel section(56) are formed on the semiconductor material. A source electrode(72) and a drain electrode(74) are respectively formed on the source and the drain sections.
