    摘要： A method is provided for controlling the channel length in a thin-film transistor (TFT). The method forms a printed ink first source/drain (S/D) structure overlying a substrate. A fluoropolymer mask is deposited to cover the first S/D structure. A boundary region is formed between the edge of the fluoropolymer mask and the edge of the printed ink first S/D structure, having a width. Then, a primary ink is printed at least partially overlying the boundary region, forming a printed ink second S/D structure, having an edge adjacent to the fluoropolymer mask edge. After removing the fluoropolymer mask, the printed ink first S/D structure edge is left separated from the printed ink second S/D structure edge by a space equal to the boundary region width. A semiconductor channel is formed partially overlying the first and second S/D structures, having a channel length equal to the boundary region width.

    摘要： A method is provided for preparing an interface surface for the deposition of an organic semiconductor material, in the fabrication of an organic thin film transistor (OTFT). A substrate is provided and a gate electrode is formed overlying the substrate. A gate dielectric is formed overlying the gate electrode. Then, source (S) and drain (D) electrodes are formed overlying the gate dielectric, exposing a gate dielectric channel interface region between the S/D electrodes. Subsequent to exposing the OTFT to a H2 or N2 plasma, a self-assembled organic monolayer is formed overlying the S/D electrodes.

The OTFT may be exposed to plasma either before or after the formation of the S/D electrodes.

    摘要： A method is provided for forming a printed top gate thin film transistor (TFT) with a short channel length. The method provides a substrate with a low surface energy top surface. A metal ink line is continuously printed across a region of the substrate top surface, and in response to the surface tension of the printed metal ink, discrete spherical ink caps are formed in the region. Then, the surface energy of the substrate top surface in the region is increased. A source metal ink line is printed overlying a source spherical ink cap contact, and a drain metal ink line, parallel to the source metal ink line, is printed overlying a drain spherical ink cap contact. After depositing a semiconductor film, a channel is formed in the semiconductor film between the source and drain spherical ink cap contacts having a channel length equal to the first distance.

    摘要： A method is provided for repairing defects in a contact printed circuit. The method provides a substrate with a contact printed circuit formed on a substrate top surface. After detecting a discontinuity in a printed circuit feature, a bias voltage is applying to at least one of a first region of the printed circuit feature or a second region of the printed circuit feature. The bias voltage may also be applied to both the first and second regions. An electric field is formed between the bias voltage and an ink delivery nozzle having a voltage potential less than the bias voltage. Conductive ink is attracted into the electric field from the ink delivery nozzle. Conductive is printed ink on the discontinuity, forming a conductive printed bridge. Typically, the ink delivery nozzle is an electrohydrodynamic (EHD) printing nozzle.

    摘要： A method is provided for fabricating a printed organic thin film transistor (OTFT) with a patterned organic semiconductor using a fluropolymer banked crystallization well. In the case of a bottom gate OTFT, a substrate is provided and a gate electrode is formed overlying the substrate. A gate dielectric is formed overlying the gate electrode, and source (S) and drain (D) electrodes are formed overlying the gate dielectric. A gate dielectric OTFT channel interface region is formed between the S/D electrodes. A well with fluropolymer containment and crystallization banks is then formed, to define an organic semiconductor print area. The well is filled with an organic semiconductor, covering the S/D electrodes and the gate dielectric OTFT channel interface. Then, the organic semiconductor is crystallized. Predominant crystal grain nucleation originates from regions overlying the S/D electrodes. As a result, an organic semiconductor channel is formed, interposed between the S/D electrodes.

    摘要： A chemical bath deposition (CBD) process is provided for forming a textured zinc oxide film pattern from a zinc oxide printed seed layer. The process provides a substrate and prints a zinc oxide seed layer in a pattern overlying the substrate. Using a CBD process, a textured zinc oxide film is grown overlying the zinc oxide seed layer pattern, where the textured zinc oxide film has a variation in film thickness of greater than 200 nanometers (nm). In one aspect, growing the textured zinc oxide film includes: preparing a ZnO precursor bath; maintaining a bath temperature of about 70 degrees C.; and, leaving the substrate in the bath for about an hour. In another aspect, growing the textured zinc oxide film includes forming a textured zinc oxide film with zinc oxide crystals having a pyramidal shape with a height of greater than 200 nm.
