Patent number: 8492212Abstract: Provided is a thin film transistor manufacture method by which a thin film transistor provided with LDD regions can be produced without increasing the number of photo masks used. An etching stopper layer (35) formed on a polycrystalline silicon film (26) of a TFT (10) is used not only as a mask to protect a channel region (27) when a source electrode and a drain electrode are formed by etching, but also as a mask when ions are implanted to form a source/drain regions (39). Thus, phosphorus, which is ion-implanted in the polycrystalline silicon film (26) to form the source/drain regions (39), is not implanted in the LDD region (38) and, accordingly, it is not necessary to additionally form a resist pattern to be used as a mask when ions are implanted.Type: GrantFiled: February 17, 2010Date of Patent: July 23, 2013Assignee: Sharp Kabushiki KaishaInventors: Tokuaki Kuniyoshi, Hidehito Kitakado, Tadayoshi Miyamoto, Kazuhide Tomiyasu, Sumio Katoh
