    摘要: An interference filter includes a layers stack comprising a plurality of layers of at least: layers of amorphous hydrogenated silicon with added nitrogen (a-Si:H,N) and layers of one or more dielectric materials, such as SiO2, SiOx, SiOxNy, a dielectric material with a higher refractive index in the range 1.9 to 2.7 inclusive, or so forth. The interference filter is designed to have a passband center wavelength in the range 750-1000 nm inclusive. Added nitrogen in the a-Si:H,N layers provides improved transmission in the passband without a large decrease in refractive index observed in a-Si:H with comparable transmission. Layers of a dielectric material with a higher refractive index in the range 1.9 to 2.7 inclusive provide a smaller angle shift compared with a similar interference filter using SiO2 as the low index layers.

    摘要: Methods of depositing a protective coating of a silicon-containing or metallic material onto a semiconductor substrate include sputtering such material from an electrode onto a semiconductor substrate in a plasma processing chamber. The protective material can be deposited onto a multi-layer mask overlying a low-k material and/or onto the low-k material. The methods can be used in dual damascene processes to protect the mask and enhance etch selectivity, to protect the low-k material from carbon depletion during resist strip processes, and/or protect the low-k material from absorption of moisture.
