  • Publication number: 20080188092
    Abstract: A method of producing an array of electronic devices, the method including the steps of: forming one or more first conductive elements of a first electronic device on a substrate and one or more second conductive elements of a second electronic device on said substrate; and forming a layer of channel material over the substrate and the first and second conductive elements to provide a first channel for, in use, the movement of charge carriers between conductive elements of said first electronic device and a second channel for, in use, the movement of charge carriers between conductive elements of said second electronic device; wherein the method also includes the step (a) of using an irradiative technique to decrease in a single step the conductivity of one or more selected portions of the layer of channel material in one or more regions between the first and second conductive elements.

  • Patent number: 6950299
    Abstract: An electronic device including first, second and third conductor layers respectively arranged as the source, drain and gate electrodes of a field effect transistor, the third conductor layer being capacitively coupled with both the first and second conductor layers but with the second conductor layer to a greater degree than with the first conductor layer, wherein the electronic device is operable as a non-linear capacitor by applying an alternating voltage across the third conductor layer and the first conductor layer whilst leaving the second conductor layer at a floating potential.

  • Publication number: 20040175963
    Abstract: Production of an electronic device by solution processing by depositing fluid including a device material or a precursor thereto onto a zone of a substrate surface between at least two opposed barriers for together controlling the spread of said fluid on the substrate surface, wherein at least one of the two opposed barriers is structured so as to facilitate controlled spillage of excess fluid out of the zone to one or more selected locations. Also, production of an electronic device by solution processing by longitudinally depositing fluid containing a device material or a precursor thereto on a patterned substrate to form a plurality of spaced longitudinal channels of said device material of controlled lateral width, wherein the substrate is patterned such that at least one lateral connection between at least one pair of adjacent channels is formed at at least one selected location without the need to carry out any lateral deposition of said fluid.
