  • Publication number: 20150380561
    Abstract: A metal oxide thin film transistor incorporating reduced hydrogen silicon-containing layers and methods of making the same are disclosed herein. The thin film transistor can include a substrate, a metal oxide semiconductor layer, a substantially hydrogen free channel interface layer and a cap layer comprising silicon formed over the channel interface layer. The method for making a thin film transistor can include depositing a metal oxide semiconductor layer over a substrate, activating a deposition gas comprising SiF4 to create an activated deposition gas, delivering the activated deposition gas to the substrate to deposit a channel interface layer comprising SiOF and depositing a cap layer over the channel interface layer and the metal oxide thin film transistor layer.

  • Patent number: 8901015
    Abstract: A method and apparatus for depositing a material layer, such as encapsulating film, onto a substrate is described. In one embodiment, an encapsulating film formation method includes delivering a gas mixture into a processing chamber, the gas mixture comprising a silicone-containing gas, a first nitrogen-containing gas, a second nitrogen-containing gas and hydrogen gas; energizing the gas mixture within the processing chamber by applying between about 0.350 watts/cm2 to about 0.903 watts/cm2 to a gas distribution plate assembly spaced about 800 mils to about 1800 mils above a substrate positioned within the processing chamber; maintaining the energized gas mixture within the processing chamber at a pressure of between about 0.5 Torr to about 3.0 Torr; and depositing an inorganic encapsulating film on the substrate in the presence of the energized gas mixture. In other embodiments, an organic dielectric layer is sandwiched between inorganic encapsulating layers.

  • Patent number: 8404502
    Abstract: The present invention generally relates to organic light emitting diode (OLED) structures and methods for their manufacture. To increase the lifetime of an OLED structure, an encapsulating layer may be deposited over the OLED structure. The encapsulating layer may fully enclose or “encapsulate” the OLED structure. The encapsulating layer may have a substantially planar surface opposite to the interface between the OLED structure and the encapsulating layer. The planar surface permits successive layers to be evenly deposited over the OLED structure. The encapsulating layer reduces any oxygen penetration into the OLED structure and may increase the lifetime of the OLED structure.

  • Publication number: 20130068161
    Abstract: An apparatus for introducing gas into a processing chamber comprising one or more gas distribution tubes having gas-injection holes which may be larger in size, greater in number, and/or spaced closer together at sections of the gas introduction tubes where greater gas conductance through the gas-injection holes is desired. An outside tube having larger gas-injection holes may surround each gas distribution tube. The gas distribution tubes may be fluidically connected to a vacuum foreline to facilitate removal of gas from the gas distribution tube at the end of a process cycle.

  • Patent number: 8225496
    Abstract: The present invention generally relates to a system that can be used to form a photovoltaic device, or solar cell, using processing modules that are adapted to perform one or more steps in the solar cell formation process. The automated solar cell fab is generally an arrangement of automated processing modules and automation equipment that is used to form solar cell devices. The automated solar fab will thus generally comprise a substrate receiving module that is adapted to receive a substrate, one or more absorbing layer deposition cluster tools having at least one processing chamber that is adapted to deposit a silicon-containing layer on a surface of the substrate, one or more back contact deposition chambers, one or more material removal chambers, a solar cell encapsulation device, an autoclave module, an automated junction box attaching module, and one or more quality assurance modules that are adapted to test and qualify the completely formed solar cell device.

  • Publication number: 20090200553
    Abstract: The present invention generally comprises a low cost TFT and a method of manufacturing a TFT. For TFTs, soda lime glass would be an attractive alternative to non-alkali glass, but a soda lime glass substrate will permit sodium to diffuse into the active layer and degrade the performance of the TFT. Substrates comprising a polyimide, because they are flexible, would also be attractive to utilize instead of non-alkali glass substrates, but the plastic substrates permit carbon to diffuse into the active layer. By depositing a silicon oxynitride adhesion layer over the soda lime glass substrate and a silicon rich barrier layer over the adhesion layer, diffusion may be reduced and deposition may occur at high temperatures. Thus, a lower cost TFT may be produced with a soda lime glass substrate or a substrate comprising a polyimide as compared to a non-alkali glass substrate.
