Patent ID: 7547574

Claim:
A method for fabricating an organic thin film transistor including a substrate, a gate electrode, a gate insulating layer, metal oxide source/drain electrodes and an organic semiconductor layer, the method comprising: treating at least one surface of the metal oxide source/drain electrodes with a self-assembled monolayer (SAM) forming compound containing a sulfonic acid group, wherein the self-assembled monolayer forming compound containing a sulfonic acid group is represented by any one of Formulae 4 to 7 below: wherein q is an integer from 1 to about 10,000, and x and y are each independently an integer from 0 to about 10; wherein r and s are integers satisfying the relations 0<r≦10,000 and 0≦s<10,000, respectively, and w and z are each independently an integer from 0 to about 20; wherein t and u are integers satisfying the relations 0<t≦10,000 and 0≦u<10,000, respectively, and v and c are each independently an integer of from 0 to about 20; wherein d and e are integers satisfying the relations 0<d≦10,000 and 0≦e<10,000, respectively, and wherein f is an integer from 0 to about 20.
