Abstract: A roller microcontact printing device and a printing method of the device are revealed. The roller microcontact printing device includes a transfer module with a transfer roller and a supply module. The supply module provides an isolating solution and a thin film material to the transfer module to form an isolation layer and a thin film layer in turn on the surface of the transfer roller. Then the thin film is transferred to a substrate by the transfer roller. The microcontact print device and method are used in a roll-to-roll printing process. Thus the production efficiency of the thin film layer on the substrate is improved and the cost is reduced.

Abstract: A thickness adjustment device for thin-film coating is revealed. The thickness adjustment device for thin-film coating includes a coating device, a support set, and a thickness adjustment unit. The coating device consists of a work piece conveyor that delivers a work piece, and a material supply unit that carries a coating material onto a surface of the work piece to form a film. The support set is connected to the coating device while the thickness adjustment unit is inserted through and mounted on the support set. The thickness adjustment unit includes a scrape part disposed correspondingly to the work piece and used for applying coating material to form the film. The thickness of the film is adjusted according to a controlling force or torque of the thickness adjustment unit that presses downward. Thus the film is coated on the work piece evenly and the film coating quality is increased.

Abstract: This invention discloses a fabrication method of organic thin-film transistors (OTFTs) using the micro-contact printing. The OTFT can be of the bottom-gate or top-gate configuration. The micro-contact printing operation of this fabrication method does not require clean-room environment and high processing temperature, and does not have the problem of 2D shrinkage of the printed patterns either. Furthermore, the pre-wetting technique employed in the micro-contact printing results in improved fidelity in the pattern transfer and solves the problems of pairing and cross-talking between neighboring patterns.
