Abstract
A TFT having a large mobility of carriers that are conducted through a channel as compared with a conventional organic TFT, and a method of manufacturing the TFT inexpensively and easily are provided. The channel is formed of a semiconductor organic molecular crystal thin film which is highly oriented, and a TFT that is large in the mobility of the carriers that are conducted through the channel, and a lyophilic TFT pattern that is surrounded by a lyophobic region on a substrate are formed, and the configuration of the pattern is featured, whereby a solution of the semiconductor organic molecules which is supplied to an appropriate region of a substrate surface including the channel is spontaneously dried in an anisotropic fashion, and highly oriented crystal is grown in the drying process.
