Abstract

See full text

Regions 106 which can be regarded as being monocrystalline are formed locally by irradiating with laser light, and at least the channel-forming region 112 is constructed using these regions. With thin-film transistors which have such a construction it is possible to obtain characteristics which are similar to those which employ monocrystals. Further, by connecting in parallel a plurality of such thin-film transistors it is possible to obtain characteristics which are effectively equivalent to those of a monocrystalline thin-film transistor in which the channel width has been increased.
