| description | PROBLEM TO BE SOLVED: To form a polycrystalline silicon semiconductor TFT of high performance. SOLUTION: A strip of polycrystalline silicon semiconductor thin film where crystal grains 20 are formed as stripes arranged in the scanning direction of a high-speed annealing beam, wherein an electric field effect mobility νL in the scanning direction and an electric field effect mobility νs in the widthwise direction of the strip are so set as to satisfy formulas, νL>=1.5.νs and νL->=55cm / V.s respectively, and the channel direction of a TFT is set conforming to the scanning direction of the annealing beam. |
