Fabrication Of Organic Thin Film Transistor Using Single Drop Of Organic Or Hybrid Insulator, Conductor And Semiconductor Materials
Project Description :

Organic thin film transistors (otfts) have been envisaged as a promising technology for their unique qualities such as flexibility, light-weight and low-cost fabrication. its potential applications include flexible displays, smart cards, rfid tags, electronic paper and other consumer electronics. different techniques such as inkjet, flexographic, gravure, offset and screen printing are used to manufacture otfts currently. here a novel technique based on a drop-cast/ inkjet process is proposed, which uses only 3 drops (distinct liquid in each drop), dispensed (and printed) in succession to manufacture otfts. an organic semiconductor when mixed with certain solvents tends to form a coffee ring like structure. when a water soluble conductor ink is dropped over the hydrophobic semiconductor, some part of it gets trapped inside the well (ring) and the rest forms a ring just outside the well, which later can be used as source and drain contacts.
