Patent ID: 7118937

Claim:
A method of manufacturing a thin film transistor array comprising switching thin film transistors, pixel electrodes, and connecting elements connecting the switching thin film transistors and the pixel electrodes, the method comprising steps of forming gate lines on a substrate; forming gate insulating film to cover the gate lines formed on the substrate; forming source and drain electrodes on the gate insulating film; performing locally a plasma process on a substrate having a hydrophobic area so as to define discrete hydrophilic and hydrophobic surfaces; forming a monolayer where a self-assembled monolayer is to be formed by exposing said hydrophilic and hydrophobic surfaces to a semiconductor vacuum deposition process such that an organic semiconductor material is only deposited as a semiconductor active layer having an island shape on a hydrophobic surface; forming a protective layer to cover the organic semiconductor island; and forming contact holes though the protective film.
