    摘要: Techniques are described to furnish an IR suppression filter that is formed on a glass substrate to a light sensor. In one or more implementations, a light sensor includes a substrate having a surface. One or more photodetectors are formed in the substrate and configured to detect light and provide a signal in response thereto. An IR suppression filter configured to block infrared light from reaching the surface is formed on a glass substrate. The light sensor also includes a plurality of color pass filters disposed over the surface. The color pass filters are configured to filter visible light to pass light in a limited spectrum of wavelengths to the one or more photodetectors. A buffer layer is disposed over the surface and configured to encapsulate the plurality of color pass filters and adhesion layer. The light sensor further includes through-silicon vias to provide electrical interconnections between different conductive layers.

    摘要: Embodiments of the invention generally relate to methods for treating a silicon-containing material on a substrate surface and performing a chamber clean process. In one embodiment, a method includes positioning a substrate containing a silicon material having a contaminant thereon within a process chamber and exposing the substrate to an etching gas containing chlorine gas and a silicon source gas while removing the contaminant and maintaining a temperature of the substrate within a range from about 500° C. to less than about 800° C. during an etching process. The method further includes exposing the substrate to a deposition gas after the etching process during a deposition process and exposing the process chamber to a chamber clean gas containing chlorine gas and the silicon source gas after the deposition process during a chamber clean process. The chamber clean process limits the etching of quartz and metal surfaces within the process chamber.

    摘要: In one example, a method of epitaxially forming a silicon-containing material on a substrate surface is presented which includes positioning a substrate into a process chamber. The substrate has a monocrystalline surface and at least a second surface, such as an amorphous surface and/or a polycrystalline surface. The substrate is exposed to a deposition gas to deposit an epitaxial layer on the monocrystalline surface and a polycrystalline layer on the second surface. The deposition gas preferably contains a silicon source and at least a second elemental source, such as a germanium source, a carbon source and/or combinations thereof. Thereafter, the method further provides exposing the substrate to an etchant gas to etch the polycrystalline layer and the epitaxial layer in a manner such that the polycrystalline layer is etched at a faster rate than the epitaxial layer. The method may further include a deposition cycle that includes repeating the exposure of the substrate to the deposition and etchant gases to form a silicon-containing material with a predetermined thickness.
