    Abstract: In some implementations, an optical interference filter includes a substrate; and a set of layers that are disposed on the substrate, wherein the set of layers includes: a first subset of layers; and a second subset of layers; wherein: each of the first subset of layers includes an aluminum nitride (AlN) material, a stress of each of the first subset of layers is between −1000 and 800 megapascals, the first subset of layers has a first refractive index with a first value, each of the second subset of layers includes at least one other material, the second subset of layers has a second refractive index with a second value that is different than the first value, and the optical interference filter has an effective refractive index greater than or equal to 95% of a highest value of the first value and the second value.

    Abstract: Reactive sputter deposition method and system are disclosed, in which a catalyst gas, such as water vapor, is used to increase the overall deposition rate substantially without compromising formation of a dielectric compound layer and its optical transmission. Addition to the sputtering or reactive gas of the catalyst gas can result in an increase of a deposition rate of the dielectric oxide film substantially without increasing an optical absorption of the film.

    Abstract: An optical filter may include a first group of layers. The first group of layers may include alternating layers of a first dielectric material, of a group of dielectric materials, and a second dielectric material of the group of dielectric materials. The optical filter may include a second group of layers. The second group of layers may include alternating layers of a third dielectric material, of the group of dielectric materials, and a fourth dielectric material of the group of dielectric materials. The optical filter may include a third group of layers. The third group of layers may include alternating layers of a fifth dielectric material, of the group of dielectric materials, a sixth dielectric material, of the group of dielectric materials, and a metal material. The third group of layers may be disposed between the first group of layers and the second group of layers.

    Abstract: An optical filter may include a set of optical filter layers disposed onto a substrate. The set of optical filter layers may include a first subset of optical filter layers comprising a first material with a first refractive index. The first material may comprise at least silicon and hydrogen. The set of optical filter layers may include a second subset of optical filter layers comprising a second material with a second refractive index. The second material is different from the first material and the second refractive index is less than the first refractive index. The set of optical filter layers may include a third subset of optical filter layers comprising a third material different from the first material and the second material.

    Abstract: A sputtering system may include a substrate. The sputtering system may include at least one target. The at least one target may include at least one coating material to coat at least one layer onto the substrate. The at least one coating material may be sputtered onto the substrate in a presence of an inert gas. The inert gas may include argon gas and helium gas.

    IPC: H01L27/146

    Abstract: An optical sensor assembly is provided in which a dark mirror coating is used to suppress stray light in the form of both unwanted reflections from non-optically active regions of the sensor assembly surface and unwanted transmission of light into the surface region of the sensor assembly. The sensor assembly includes an image sensor positioned in a substrate adjacent to substrate surface areas that are not optically active. A dark mirror coating covering those surface areas significantly reduces reflections from non-optically active surface regions and improves image sensor performance in terms of signal-to-noise ratio and reduction in the appearance of “ghost” images, in turn enhancing the accuracy and precision of the sensor. The dark mirror coating may in the alternative, or in addition, be positioned underneath an optical filter, depending on the structure, material, and requirements of a particular sensor assembly.
