摘要:
An electronic device, including a substrate, a plurality of first semiconductor islands on the substrate, a plurality of second semiconductor islands on the substrate, a first dielectric film on the first subset of the semiconductor islands, second dielectric film on the second semiconductor islands, and a metal layer in electrical contact with the first and second semiconductor islands. The first semiconductor islands and the first dielectric film contain a first diffusible dopant, and the second semiconductor islands and the second dielectric layer film contain a second diffusible dopant different from the first diffusible dopant. The present electronic device can be manufactured using printing technologies, thereby enabling high-throughput, low-cost manufacturing of electrical circuits on a wide variety of substrates.
摘要:
A method for making an electronic device, such as a MOS transistor, including the steps of forming a plurality of semiconductor islands on an electrically functional substrate, printing a first dielectric layer on or over a first subset of the semiconductor islands and optionally a second dielectric layer on or over a second subset of the semiconductor islands, and annealing. The first dielectric layer contains a first dopant, and the (optional) second dielectric layer contains a second dopant different from the first dopant. The dielectric layer(s), semiconductor islands and substrate are annealed sufficiently to diffuse the first dopant into the first subset of semiconductor islands and, when present, the second dopant into the second subset of semiconductor islands.

A RF MOS- or nonlinear device-based surveillance identification tag, and methods for its manufacture and use. The tag includes an inductor, a capacitor plate coupled to the inductor, a dielectric film on the capacitor plate, a semiconductor component on the dielectric film, and a conductor providing electrical communication between the semiconductor component and the inductor. The method of manufacture includes depositing a semiconductor material/precursor on a dielectric film; forming a semiconductor component from the semiconductor material/precursor; forming a conductive structure at least partly on the semiconductor component; and etching the electrically functional substrate to form an inductor and/or a second capacitor plate. The method of use includes causing/inducing a current in the tag sufficient to generate detectable electromagnetic radiation; detecting the radiation; and selectively deactivating the tag. The present invention provides a low cost tag capable of operating at MHz frequencies and in frequency division and/or multiplication modes.

摘要:
Compositions, inks and methods for forming a patterned silicon-containing film and patterned structures including such a film. The composition generally includes (a) passivated semiconductor nanoparticles and (b) first and second cyclic Group IVA compounds in which the cyclic species predominantly contains Si and/or Ge atoms. The ink generally includes the composition and a solvent in which the composition is soluble. The method generally includes the steps of (1) printing the composition or ink on a substrate to form a pattern, and (2) curing the patterned composition or ink. In an alternative embodiment, the method includes the steps of (i) curing either a semiconductor nanoparticle composition or at least one cyclic Group IVA compound to form a thin film, (ii) coating the thin film with the other, and (iii) curing the coated thin film to form a semiconducting thin film. The semiconducting thin film includes a sintered mixture of semiconductor nanoparticles in hydrogenated, at least partially amorphous silicon and/or germanium. The thin film exhibits improved conductivity, density, adhesion and/or carrier mobility relative to an otherwise identical structure made by an identical process, but without either the semiconductor nanoparticles or the hydrogenated Group IVA element polymer. The present invention advantageously provides semiconducting thin film structures having qualities suitable for use in electronics applications, such as display devices or RF ID tags, while enabling high-throughput printing processes that form such thin films in seconds or minutes, rather than hours or days as with conventional photolithographic processes.

摘要:
A method of making hydrogenated Group IVA compounds having reduced metal-based impurities, compositions and inks including such Group IVA compounds, and methods for forming a semiconductor thin film. Thin semiconducting films prepared according to the present invention generally exhibit improved conductivity, film morphology and/or carrier mobility relative to an otherwise identical structure made by an identical process, but without the washing step. In addition, the properties of the present thin film are generally more predictable than those of films produced from similarly prepared (cyclo)silanes that have not been washed according to the present invention. The present invention advantageously provides semiconducting thin film structures having qualities suitable for use in electronics applications, such as display devices or RF ID tags, while enabling high-throughput manufacturing processes that form such thin films in seconds or minutes, rather than hours or days as with conventional photolithographic processes.
