    • A phase shift keyed demodulator includes first and second beam splitters, a first optical path, a second optical path, and a wavelength tuner. The first beam splitter splits an input signal into first and second output signals. The second beam splitter splits each first and second output signal into a transmitted signal and a reflected signal. The first optical path includes an optical path of each transmitted signal from a beam splitting surface to a reflector and back to the beam splitting surface. The second optical path includes an optical path of each reflected signal from the beam splitting surface to a mirror surface and back to the beam splitting surface. A path difference introduces a delay between the transmitted signal and the reflected signal. The wavelength tuner tunes the demodulator to a predetermined central wavelength and introduces a phase shift between first and second transmitted signals.

    • Methods, materials, and systems are described for forming conformal dielectric layers containing silicon and nitrogen (e.g., a silicon-nitrogen-hydrogen (Si—N—H) film) from a carbon-free silicon-and-nitrogen precursor and radical-nitrogen precursor. The carbon-free silicon-and-nitrogen precursor is predominantly excited by contact with the radical-nitrogen precursor. Because the silicon-and-nitrogen film is formed without carbon, the conversion of the film into hardened silicon oxide is done with less pore formation and less volume shrinkage. The deposited silicon-and-nitrogen-containing film may be wholly or partially converted to silicon oxide which allows the optical properties of the conformal dielectric layer to be selectable. The deposition of a thin silicon-and-nitrogen-containing film may be performed at low temperature to form a liner layer in a substrate trench. The low temperature liner layer has been found to improve the wetting properties and allows flowable films to more completely fill the trench.
    • 描述了用于形成含有硅和氮的保形电介质层(例如,硅 - 氮 - 氢(Si-N-H)膜)的方法,材料和系统,其来自无碳硅氮前驱物和自由基 - 氮前体。 主要通过与自由基 - 氮前体接触激发无碳硅和氮前体。 由于硅和氮膜不形成碳,所以将薄膜转化成硬化的氧化硅是在较少的孔形成和较小的体积收缩下进行的。 沉积的含硅和氮的膜可以全部或部分地转化为氧化硅,这允许保形介电层的光学特性是可选择的。 可以在低温下进行薄的含硅和氮的膜的沉积,以在衬底沟槽中形成衬垫层。 已经发现低温衬里层改善了润湿性能,并允许可流动膜更完全地填充沟槽。

    • Methods of forming silicon oxide layers are described. The methods include concurrently combining plasma-excited (radical) steam with an unexcited silicon precursor. Nitrogen may be supplied through the plasma-excited route (e.g. by adding ammonia to the steam) and/or by choosing a nitrogen-containing unexcited silicon precursor. The methods result in depositing a silicon-oxygen-and-nitrogen-containing layer on a substrate. The oxygen content of the silicon-oxygen-and-nitrogen-containing layer is then increased to form a silicon oxide layer which may contain little or no nitrogen. The increase in oxygen content may be brought about by annealing the layer in the presence of an oxygen-containing atmosphere and the density of the film may be increased further by raising the temperature even higher in an inert environment.
    • 描述形成氧化硅层的方法。 这些方法包括同时将等离子体激发(自由基)蒸汽与未催化的硅前体组合。 可以通过等离子体激发途径(例如通过向蒸汽中加入氨)和/或通过选择含氮的未催化的硅前体来供应氮。 该方法导致在衬底上沉积含硅 - 氧和氮的层。 然后增加硅 - 氧 - 和 - 含氮层的氧含量以形成可能含有很少或不含氮的氧化硅层。 氧含量的增加可以通过在含氧气氛的存在下退火层而实现,并且通过在惰性环境中更高的温度升高可以进一步提高膜的密度。
