PROBLEM TO BE SOLVED: To provide a semiconductor device, which is high in the performance of operation and reliability, and also to provide its forming method.;SOLUTION: A drive circuit and pixel portion are formed on the same substrate, the gate electrode of a TFT formed on the drive circuit and the pixel portion has tapered section, and an n-channel type TFT formed on the drive circuit has an LDD region partly covered by the tapered section of the gate electrode. The semiconductor device, having the LDD region such as this, this can decrease OFF-state current and suppress the decay of deterioration of characteristics.;COPYRIGHT: (C)2005,JPO&NCIPI
