Patent number: 6344660Abstract: A thin film transistor (TFT) device structure based on an organic semiconductor material, that exhibits a high field effect mobility, high current modulation and a low sub-threshold slope at lower operating voltages than the current state of the art organic TFT devices. The structure comprises a suitable substrate disposed with he following sequence of features: a set of conducting gate electrodes covered with a high dielectric constant insulator, a layer of the organic semiconductor, sets of electrically conducting source and drain electrodes corresponding to each of the gate lines, and an optional passivation layer that can overcoat and protect the device structure. Use of high dielectric constant gate insulators exploits the unexpected gate voltage dependence of the organic semiconductor to achieve high field effect mobility levels at very low operating voltages.Type: GrantFiled: June 2, 1999Date of Patent: February 5, 2002Assignee: International Business Machines CorporationInventors: Christos Dimitrios Dimitrakopoulos, Peter Richard Duncombe, Bruce K.
