摘要： A compact variable optical attenuator having optical-tap functionality is described comprising a planar waveguide attenuator, a lens, and a photodetector. Input and output waveguides are located close to the optical axis of the lens, which reduces optical aberrations and insertion loss. The waveguide attenuator works by light absorption with virtually no scattered light present, which improves fidelity of measurements of the tapped optical power by the photodetector. The entire tap-attenuator assembly is packaged into a small form pluggable (SFP) package having two optical connectors.

摘要： A method of forming a dielectric layer is described. The method first deposits a silicon-nitrogen-and-hydrogen-containing (polysilazane) layer by radical-component chemical vapor deposition (CVD). The silicon-nitrogen-and-hydrogen-containing layer is formed by combining a radical precursor (excited in a remote plasma) with an unexcited carbon-free silicon precursor. A silicon oxide capping layer may be formed from a portion of the carbon-free silicon-nitrogen-and-hydrogen-containing layer to avoid time-evolution of underlying layer properties prior to conversion into silicon oxide. Alternatively, the silicon oxide capping layer is formed over the silicon-nitrogen-and-hydrogen-containing layer. Either method of formation involves the formation of a local plasma within the substrate processing region.

摘要： 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.

摘要： 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.

摘要： A method of forming a silicon oxide layer is described. The method increases the oxygen content of a dielectric layer by curing the layer in a two-step ozone cure. The first step involves exposing the dielectric layer to ozone while the second step involves exposing the dielectric layer to ozone excited by a local plasma. This sequence can reduce or eliminate the need for a subsequent anneal following the cure step. The two-step ozone cures may be applied to silicon-and-nitrogen-containing film to convert the films to silicon oxide.

摘要： 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.

摘要： A plasma treatment process for increasing the tensile stress of a silicon wafer is described. Following deposition of a dielectric layer on a substrate, the substrate is lifted to an elevated position above the substrate receiving surface and exposed to a plasma treatment process which treats both the top and bottom surface of the wafer and increases the tensile stress of the deposited layer. Another embodiment of the invention involves biasing of the substrate prior to plasma treatment to bombard the wafer with plasma ions and raise the temperature of the substrate. In another embodiment of the invention, a two-step plasma treatment process can be used where the substrate is first exposed to a plasma at a processing position directly after deposition, and then raised to an elevated position where both the top and bottom of the wafer are exposed to the plasma.
