    摘要: An image sensor having shield structures and methods of forming the same are provided. Generally, the image sensor includes: (i) substrate having at least one photosensitive element formed therein; (ii) a dielectric layer overlying the substrate and the photosensitive element; and (iii) an annular reflective waveguide disposed in the dielectric layer above the photosensitive element to reduce cross-talk between adjacent elements of the sensor while increasing sensitivity of the sensor. In certain embodiments, the sensor further includes a photoshield disposed in the dielectric above the photosensitive element and about the waveguide to further reduce the possibility of cross-talk. Other embodiments are also disclosed.

    摘要: In one embodiment, a method for forming a tungsten-containing material on a substrate is provided which includes positioning a substrate containing a metal nitride barrier layer within a process chamber and exposing the substrate to a reagent gas containing diborane to form a reagent layer on the metal nitride barrier layer. The method further provides exposing the substrate sequentially to a tungsten precursor and a reductant to form a nucleation layer during an atomic layer deposition (ALD) process and subsequently depositing a bulk layer over the nucleation layer. The bulk layer may contain copper, but generally contains tungsten deposited by a chemical vapor deposition (CVD) process. In some examples, the bulk layer may be used to fill apertures within the substrate.

    摘要: In one embodiment, a method for depositing a boride-containing barrier layer on a substrate is provided which includes exposing the substrate sequentially to a boron-containing compound and a metal precursor to form a first boride-containing layer during a first sequential chemisorption process and exposing the substrate to the boron-containing compound, the metal precursor, and a second precursor to form a second boride-containing layer on the first boride-containing layer during a second sequential chemisorption process. In one example, the metal precursor contains tungsten hexafluoride and the boron-containing compound contains diborane. In another embodiment, a contact layer is deposited over the second boride-containing layer. The contact layer may contain tungsten and be deposited by a chemical vapor deposition process. Alternatively, the contact layer may contain copper and be deposited by a physical vapor deposition process. In other examples, boride-containing layers may be formed at a temperature of less than about 500° C.

    摘要: A method and system to form a refractory metal layer over a substrate includes introduction of a reductant, such as PH3 or B2H6, followed by introduction of a tungsten containing compound, such as WF6, to form a tungsten layer. It is believed that the reductant reduces the fluorine content of the tungsten layer while improving the step coverage and resistivity of the tungsten layer. It is believed that the improved characteristics of the tungsten film are attributable to the chemical affinity between the reductants and the tungsten containing compound. The chemical affinity provides better surface mobility of the adsorbed chemical species and better reduction of WF6 at the nucleation stage of the tungsten layer. The method can further include sequentially introducing a reductant, such as PH3 or B2H6, and a tungsten containing compound to deposit a tungsten layer. The formed tungsten layer can be used as a nucleation layer followed by bulk deposition of a tungsten layer utilizing standard CVD techniques. Alternatively, the formed tungsten layer can be used to fill an aperture.
