  • Publication number: 20230203636
    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 interference filter includes a substrate and a plurality of sets of layers that are disposed over the substrate. Each set of layers includes: a first layer that comprises at least a first oxide; a second layer disposed over the first layer that comprises at least a second oxide; and a third layer disposed over the second layer that comprises at least hydrogen and silicon. The optical interference filter may be configured to transmit light associated with a first spectral range (e.g., from 585 nanometers to 700 nanometers) and to block light associated with a second spectral range (e.g., from 440 nanometers to 475 nanometers). The third layer may have an extinction coefficient for the second spectral range that is greater than four times an extinction coefficient of the third layer for the first spectral range.
