    摘要: An improved thin film inductor design is described. A spiral geometry is used to which has been added a core of high permeability material located at the center of the spiral. If the high permeability material is a conductor, care must be taken to avoid any contact between the core and the spiral. If a dielectric ferromagnetic material is used, this constraint is removed from the design. Several other embodiments are shown in which, in addition to the high permeability core, provide low reluctance paths for the structure. In one case this takes the form of a frame of ferromagnetic material surrounding the spiral while in a second case it has the form of a hollow square located directly above the spiral.

    摘要: The invention provides a method for fabricating a shallow trench isolation which is not susceptable to buried contact trench formation. The invention also provides immunity from the STI “kink effect,” as well as benefits associated with nitridation. The process begins by forming a pad oxide layer on a semiconductor substrate. A nitride layer is formed on the pad oxide layer. The nitride layer, the pad oxide layer, and the semiconductor substrate are patterned to form trenches. Next, a fill oxide layer is formed over the nitride layer, the pad oxide layer, and the semiconductor substrate. The fill oxide layer is chemical-mechanical polished, stopping on the nitride layer to form fill oxide regions. N2 ions are implanted into the fill oxide regions. An anneal is performed to form a buried oxynitride layer. The buried oxynitride layer is partially above the level of the top surface of the semiconductor substrate and partially below the level of the top surface of the semiconductor substrate. The nitride layer is removed. Then, the pad oxide layer and portions of the fill oxide regions are removed using the buried oxynitride layer as an etch stop, forming shallow trench isolations.

    摘要: This invention provides a method for forming a self aligned contact without key holes using a two step sidewall spacer deposition. The process begins by providing a semiconductor structure having a device layer, a first inter poly oxide layer (IPO-1), and a conductive structure (such as a bit line) thereover, and having a contact area on the device layer adjacent to the conductive structure. The semiconductor structure can further include an optional etch stop layer overlying the first inter poly oxide layer. The conductive structure comprises at least one conductive layer with a hard mask thereover. A first spacer layer is formed over the hard mask and the IPO-1 layer and anisotropically etched to form first sidewall spacers on the sidewalls of the conductive structure up to a level above the bottom of the hard mask and below the level of the top of the hard mask such that the profile of the first sidewall spacers are not concave at any point. A second spacer layer is formed over the first sidewall spacers and anisotropically etched to form second sidewall spacers, having a profile that is not concave at any point. A second inter poly oxide layer is formed over the second sidewall spacers, the hard mask, and the IPO-1 layer, whereby the second inter poly oxide layer is free from key holes. A contact opening is formed in the second inter poly oxide layer and the first inter poly oxide layer over the contact area. A contact plug is formed in the contact openings.

    摘要: A process for creating an insulator filled, shallow trench, in a semiconductor substrate, in which the insulator layer in the shallow trench, is not exposed to procedures used to remove defining composite insulator layers, has been developed. The process features creating a lateral recess, in a thick silicon nitride layer, used as a component of a composite insulator layer, where the composite insulator layer is used for subsequent definition of the shallow trench, in the semiconductor substrate. An insulator deposition, filling openings, and recesses, in the composite insulator layer, and filling the shallow trench, followed by removal of excess insulator fill, on the top surface of the composite insulator layer, results in the formation of a "T" shape insulator, comprised of an insulator shape, in the shallow trench, and comprised of a wider insulator shape, located in the composite insulator shape, with the lateral recess in the thick silicon nitride layer, and with the wider insulator shape, overlying the narrow, insulator shape, in the shallow trench. The insulator, in the shallow trench, is protected from the procedure used to remove components of the composite insulator layer, by the wider insulator shape.
