Patent ID: 7344914

Claim:
A process of making the organic semiconductor element having multi protection layers, comprising the step of providing an organic thin film transistor; forming a first protection layer on said organic thin film transistor; forming a second protection layer on said first protection layer, the thickness of said second protection layer is sufficient to serve as the photo spacers, wherein said second protection layer is made of a developable material, which is SU-8 2002 photoresist; and patterning said second protection layer, so as to form said organic semiconductor element, wherein the step of patterning said second protection layer is to form a contact hole, which is used to penetrate said protection layer and said first protection layer thus to expose said organic thin film transistor, wherein after patterning said second protection layer, the process further comprising the step of forming an electrode on said second protection layer, said electrode is connected electrically to said thin film transistor via contact hole.
