ORGANIC FIELD EFFECT TRANSISTOR AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To further enhance carrier mobility without deteriorating n-type transistor characteristics by composing both a semiconductor layer and an insulator layer material with organic compounds and further using macromolecular substances having no hydroxide group as a substance that forms the insulator layer in a TFT having a conductive layer/insulator layer/semiconductor layer structure. SOLUTION: In an organic field effect transistor (OFET) having the conductor layer 2/insulator layer 3/semiconductor layer 4 structure, the substance that forms the semiconductor layer 4 is an organic compound, and the substance that forms the insulator layer 3 includes a macromolecule obtained by polymerizing or copolymerizing a monomer expressed by the chemical formula (1): CH2=CHCOO-(CH2)2-CN and/or a monomer expressed by the chemical formula (2): CH2=C(CH3)COO-(CH2)2-CN. Therefore, carrier mobility can be further enhanced without deteriorating the n-type transistor characteristics. COPYRIGHT: (C)2009,JPO&INPIT
