  • Publication number: 20140209800
    Abstract: An NDIR gas detector includes a photodetector for detecting a portion of stray visible light emitted from an incandescent lamp so as to generate an induced electrical signal, which is compared with a preset reference signal associated with a predetermined constant level of the stray visible light corresponding to a constant temperature of the lamp so as to obtain a level difference between the induced electrical signal and the reference signal. Electrical power supplied to the lamp is repeatedly regulated based on the level difference until the induced electrical signal and the reference signal have the same level, thereby stabilizing IR emission of the lamp in response to the lamp being kept at the constant temperature.

  • Patent number: 8633076
    Abstract: A method includes growing a plurality of parallel mandrels on a surface of a semiconductor substrate, each mandrel having at least two laterally opposite sidewalls and a predetermined width. The method further includes forming a first type of spacers on the sidewalls of the mandrels, wherein the first type of spacers between two adjacent mandrels are separated by a gap. The predetermined mandrel width is adjusted to close the gap between the adjacent first type of spacers to form a second type of spacers. The mandrels are removed to form a first type of fins from the first type of spacers, and to form a second type of fins from spacers between two adjacent mandrels. The second type of fins are wider than the first type of fins.

  • Patent number: 8623728
    Abstract: A method for producing a SiGe stressor with high Ge concentration is provided. The method includes providing a semiconductor substrate with a source area, a drain area, and a channel in between; depositing the first SiGe film layer on the source area and/or the drain area; performing a low temperature thermal oxidation, e.g., a high water vapor pressure wet oxidation, to form an oxide layer at the top of the first SiGe layer and to form the second SiGe film layer with high Ge percentage at the bottom of the first SiGe film layer without Ge diffusion into the semiconductor substrate; performing a thermal diffusion to form the SiGe stressor from the second SiGe film layer, wherein the SiGe stressor provides uniaxial compressive strain on the channel; and removing the oxide layer. A Si cap layer can be deposited on the first SiGe film layer prior to performing oxidation.
