The organic active layer includes the organic semiconducting copolymer. The gate insulating layer includes a ferroelectric insulator, inorganic insulator, or organic insulator.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Catalyst: The copolymer is manufactured using a palladium catalyst of formula: PdL4 or PdL2Cl2, and nickel catalyst of formula: NiL'or NiL'Cl2.L=ligand chosen from triphenylphosphine, triphenylarsine and triphenylphosphite;andL'=ligand chosen from 1,5-cyclooctadiene, 1,3-diphenylphosphinopropane, 1,2-bis(diphenylphosphino)ethane, and 1,4-diphenylphosphinobutane.Preferably, the nickel catalyst is bis(1,5-cyclooctadiene)nickel(0), 1,3-diphenylphosphinopropane nickel(II)chloride, or 1,2-bis(diphenylphosphino)ethane nickel(II)chloride.    TECHNOLOGY FOCUS - POLYMERS - Preparation (claimed): The new organic semiconducting copolymer is obtained by copolymerizing bithiazole compounds of formulae (2,3) and aromatic-ring-containing compound of formula: Y'3-(-D'2-)z-Y'4.Y'1-Y'4=halo, trialkyl tin group, or borane group;andz=1-4. Preferred Definitions:    D'1,D'2=group chosen from groups of formulae (i-xxiv).    The heteroaromatic ring contains sulfur heteroatom, oxygen heteroatom, and/or selenium heteroatom, and has heteroaromatic ring has 5 members.    EXAMPLE - (In g) 2,2'-bis-(5-bromo-3-dodecyl-thiophen-2-yl)-4,4'-didodecyl-(5,5')bithiazolyl (0.71), bis(2-(5-bromo-3-ethylthien-2-yl)-4-ethyl-1,3-thiazole)-2,2'-bithiophene (0.81), and bis(trimethylstenyl)thiophene (sic) (0.6) were added to a reactor under nitrogen atmosphere, and heated to completely dissolve in anhydrous dimethylformamide. Tetrakis(triphenylphosphine)palladium was added as polymerization catalyst and reacted at 85 degrees C for 5-6 hours. After reaction completion, the reaction mixture was cooled to room temperature and filtered. The obtained solid was washed twice with hydrochloric acid solution/chloroform, twice with ammonium hydroxide/chloroform, and twice with water/chloroform and then reprecipitated in methanol for recovery. The resulting product was dried to obtain an indigo-colored organic semiconducting polymer having a number average molecular weight of 250000, with a yield of 56%. The obtained copolymer provided organic thin film transistor having charge mobility of 0.12 cm2/V, a current on/off ratio of 4x 105, and a breaking leakage current of 1x 10-11 A.
