  • Publication number: 20100078640
    Abstract: A fabrication process for a device such as a backplane for a flat panel display includes depositing thin film layers on a substrate, forming a 3D template overlying the thin film layers, and etching the 3D template and the thin film layers to form gate lines and transistors from the thin film layers. An insulating or passivation layer can then be deposited on the gate lines and the transistors, so that column or data lines can be formed on the insulating layer.

  • Publication number: 20060236933
    Abstract: A system comprises a processing chamber for maintaining a hydrogen plasma at low pressure. The processing chamber has a long, wide, thin geometry to favor deposition of thin-film silicon on sheet substrates over the chamber walls. The sheet substrates are moved through between ends. A pair of opposing radio frequency electrodes above and below the workpieces are electrically driven hard to generate a flat, pancaked plasma cloud in the middle spaces of the processing chamber. A collinear series of gas injector jets pointed slightly up on a silane-jet manifold introduce 100% silane gas at high velocity from the side in order to roll the plasma cloud in a coaxial vortex. A second such silane-jet manifold is placed on the opposite side and pointed slightly down to further help roll the plasma and maintain a narrow band of silane concentration.

  • Patent number: 7121496
    Abstract: The present invention includes a method and system for correcting web deformation during a roll-to-roll process. The present invention includes controllable mechanical components that are capable of dynamically adjusting the planarity of the web during the roll-to-roll process. By adjusting the web during the roll-to-roll process, the accuracy of the layer-to layer alignment of successive patterning steps is greatly increased thereby enabling the production of electronic structures with lower overlap capacitance and higher resolution. A first aspect of the present invention is a method for correcting web deformation during a roll-to-roll process. The method includes initiating a roll-to-roll process involving a flexible web substrate, detecting deformation in the flexible web substrate during the roll-to-roll process and dynamically aligning the flexible web substrate based on the detected deformation.

  • Publication number: 20060188823
    Abstract: Provided is a low cost system and method for forming electronic devices, especially large surface area devices. The process of imprint lithography is combined with alternate manufacturing techniques to fabricate the devices. Initially, a template imprints a three-dimensional pattern into a resist layer deposited on a flexible substrate. The resist layer is cured using ultraviolet light or other curing techniques. After curing, the 3-D pattern is modified using one of several techniques to include inkjetting, electrodeposition or laser patterning. In one embodiment, a semi-fluid material may be jetted into channels formed in the pattern, thereby forming conductive or insulating lead lines. Alternatively, a two-dimensional pattern may be jetted onto the resist layer. Final processing may include multiple etch-mask-etch steps. The integration of techniques into a single system provides a low cost, efficient method for manufacturing high quality, large surface area electronic devices.
