    摘要： A spacer, a split gate flash memory cell, and related method of forming the same. In one aspect, a composite spacer includes a first spacer insulating layer having a first deposition distribution that varies as a function of a location on a substrate. The composite spacer also includes a second spacer insulating layer having a second deposition distribution that varies in substantial opposition to the first deposition distribution. In another aspect, a composite spacer includes a first spacer insulating layer having a substantially uniform deposition distribution across a surface thereof. The composite spacer also includes a second spacer insulating layer having a varying deposition distribution with a thinner composition in selected regions of the memory cell. In another aspect, a coupling spacer provides for a conductive layer that extends between a floating gate and a substrate insulating layer adjacent a source recessed into the substrate of the memory cell.

    摘要： An image sensor includes a double-microlens structure with an outer microlens aligned over an inner microlens, both microlenses aligned over a corresponding photosensor. The inner or outer microlens may be formed by a silylation process in which a reactive portion of a photoresist material reacts with a silicon-containing agent. The inner or outer microlens may be formed by step etching of a dielectric material, the step etching process including a series of alternating etch steps including an anisotropic etching step and an etching step that causes patterned photoresist to laterally recede. Subsequent isotropic etching processes may be used to smooth the etched step structure and form a smooth lens. A thermally stable and photosensitive polymeric/organic material may also be used to form permanent inner or outer lenses. The photosensitive material is coated then patterned using photolithography, reflowed, then cured to form a permanent lens structure.

    摘要： A method of fabricating word-line spacers comprising the following steps. A substrate having an inchoate split-gate flash memory structure formed thereover is provided. A conductive layer is formed over the substrate and the inchoate split-gate flash memory structure. The conductive layer having: a upper portion and lower vertical portions over the inchoate split-gate flash memory structure; and lower horizontal portions over the substrate. A dual-thickness oxide layer is formed over the conductive layer and has a greater thickness over the upper portion of the conductive layer. The oxide layer is partially etched back to remove at least the oxide layer from over the lower horizontal portions of the conductive layer to expose the underlying portions of the conductive layer. Then etching: away the exposed portions of the conductive layer over the substrate; and through at least a portion of the thinned oxide layer and into the exposed underlying portion of the conductive layer to expose a portion of the inchoate split-gate flash memory structure and to form the word-line spacers adjacent the inchoate split-gate flash memory structure.

    摘要： A method for making crown-shaped capacitors with uniform capacitance from the center to the edge of the DRAM device is achieved. The uniform capacitance is achieved using a two-step planarization process or a uniformly deposited CVD sacrificial layer. After forming a first conducting layer in openings in an insulator, a sacrificial layer is spin coated on the substrate. The non-uniformity, by virtue of the spin coating, is then partially polished back to form a globally uniform surface followed by a plasma etch-back to leave portions of the sacrificial layer of equal height in the openings. The first conducting layer in the openings is uniformly recessed for making capacitors having uniform values across the DRAM device. In a second approach a relatively thin uniform CVD polymer is deposited requiring only a single polishing step or etch-back to achieve uniform portions of the polymer in the openings.
