Patent ID: 8860018

Claim:
A semiconductor device comprising: a substrate having thereon a gate electrode, a gate insulating layer, source/drain electrodes, and a channel-forming region, wherein the channel-forming region is composed of a anthanthrene based compound represented by the following structural formula (2): wherein X represents oxygen; n represents an integer of from 1 to 20; m represents an integer of from 1 to 9; a bonding position in the A segment to the B segment is at least one of from the 1-position to the 5-position and from the 7-position to the 11-position; a bonding position in the B segment to the A segment is at least one of from the 1-position to the 5-position and from the 7-position to the 11-position; a bonding position in the B segment to the C segment is at least one of from the 1-position to the 5-position and from the 7-position to the 11-position; a bonding position in the C segment to the B segment is at least one of from the 1-position to the 5-position and from the 7-position to the 11-position; and each of [Y] represents a phenyl group and [Z] represents an ethyl group, wherein each of the substituents R 1 , R 2 , R 3 , R 4 , R 5 , R 7 , R 8 , R 9 , R 10 and R 11 independently represents a substituent selected from the group consisting of hydrogen, an alkyl group, an alkenyl group, an aryl group, an arylalkyl group, an aromatic heterocyclic ring and a halogen atom.
