The method comprises: forming a gate metal layer (35), forming a step-like gate structure (352) by one patterning process; performing a first ion implantation procedure to forming a first heavily doped area (39a) and a second heavily doped area (39b), the first heavily doped area (39a) being separated apart from the second heavily doped area (39b) by a first length; forming a gate electrode (353) from the step-like gate structure (352); performing a second ion implantation procedure to form a first lightly doped area (38a) and a second lightly doped area (38b), the first lightly doped area (38a) being separated apart from the second lightly doped area (38b) by a second length less than the first length. By the above method, the process for manufacturing the LTPS TFT having the lightly doped source/drain structure can be simplified."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Thin film transistor and manufacturing method thereof, display device","description":"A thin film transistor, its manufacturing method, and a display device are provided.
