  • Patent number: 7161171
    Abstract: A material including a glass or vitroceramic substrate having a first layer and a second layer deposited thereon, each of the first and second layers including at least one transparent conducting oxide (TCO). The first layer has a roughness of more than 1 nm and the second layer has a roughness less than or equal to 1 nm. A transmittance in the visible wavelength range of the material is at least 80%. The work function of the second layer is greater than the work function of the first layer and is greater than 4.6 eV.

  • Patent number: 7007709
    Abstract: The present invention relates to microfluidic devices and to their method of manufacture. The microfluidic devices are original by their specific structure (of sandwich type) and by the materials from which they are made (mainly glasses, glass ceramics, ceramics), and also by their specific method of manufacture, which is based on a vacuum-forming operation. The microfluidic device includes a first assembly including a microstructure and a first substrate, wherein the microstructure is constructed and arranged on the substrate under vacuum. A second assembly includes a second substrate positioned on the microstructure after the first assembly is presintered and adhered thereto by heat treatment to form a one-piece microstructure defining at least one recess between the first and second substrates.

  • Publication number: 20040130005
    Abstract: Polycrystalline silicon in semiconductor device is usually crystallized at high temperature annealing. Generally a low heat conducting underlayer is needed to protect substrate and silicon from high temperature crystallization. This invention proposes a new underlayer that improves silicon crystallization and protects substrate during the annealing process. The semiconductor device is a thin film transistor suitable for use in such applications as liquid crystal displays, light emitting diodes, imaging sensors and photovoltaic cells.
