Filed: 2002-01-11
Abstract: <P>PROBLEM TO BE SOLVED: To prevent a TFT from being deteriorated in characteristics by allowing to reduce an amount of a light incident from each direction.  <P>SOLUTION: The method for manufacturing the semiconductor device comprises the steps of forming a source electrode 38 and a drain electrode 39 disposed between a semiconductor film 34 and an upper shielding film 42 in a tabular state of a long longitudinal shape in a direction perpendicular to a channel direction of a metal, and forming both ends so as to have an inverted tapered shape. Thus, since a light reflected from below becomes a shape suitable to externally reflect and an upper surface side is largely formed, a radiation of a light sneaked around the upper shield film to the semiconductor film 34 is reduced, and light leakage can be suppressed by the radiation of the light to the film 34 as a channel of the TFT. Since a peripheral edge of the film 42 is formed to have a forward tapered shape, the device has a structure suitable to reflect the light radiated from an upper part in an external part direction.  <P>COPYRIGHT: (C)2003,JPO
