Claim Text:
1. A thin film transistor, comprising: a silicon substrate having a main surface formed with a stripe-like or grid-like concave-convex configuration; a channel layer formed of a plurality of carbon nanowall thin films which are disposed on a plurality of protruding portions along a length direction of the protruding portion of the concave-convex shape, and respectively grows in a normal direction of the silicon substrate; a source electrode at least contacting a first side surface of each of the plurality of carbon nanowall thin films which is in parallel to a thickness direction of the carbon nanowall thin film; a drain electrode disposed so as to be opposed to the source electrode in an in-plane direction of the carbon nanowall thin film, and at least contacting a second side surface of each of the plurality of carbon nanowall thin films which is opposite to the first side surface; a gate electrode; and an insulating film disposed between the plurality of carbon nanowall thin films and the gate electrode.
