    摘要: An electrical component, such as a DRAM semiconductor memory or a field-effect transistor is fabricated. At least one capacitor having a dielectric (130) and at least one connection electrode (120, 140) are fabricated. To enable the capacitors fabricated to have optimum storage properties even for very small capacitor structures, the dielectric (130) or the connection electrode (120, 140) are formed in such a manner that transient polarization effects are prevented or at least reduced.

    摘要: A storage capacitor, suitable for use in a DRAM cell, is at least partially formed above a substrate surface and includes: a storage electrode at least partially formed above the substrate surface, a dielectric layer formed adjacent the storage electrode, and a counter electrode formed adjacent the dielectric layer, the counter electrode being isolated from the storage electrode by the dielectric layer, wherein the storage electrode is formed as a body which is delimited by at least one curved surface having a center of curvature outside the body in a plane parallel to the substrate surface. According to another configuration, the storage electrode is formed as a body which is delimited by at least one set having two contiguous planes, the two planes extending perpendicularly with respect to the substrate surface, a point of intersection of normals of the two planes lying outside the body.

    摘要: A process for fabricating a single-sided semiconductor deep trench structure filled with polysilicon trench fill material includes the following steps. Form a thin film, silicon nitride, barrier layer over the trench fill material. Deposit a thin film of an amorphous silicon masking layer over the barrier layer. Perform an angled implant into portions of the amorphous silicon masking layer which are not in the shadow of the deep trench. Strip the undoped portions of the amorphous silicon masking layer from the deep trench. Then strip the newly exposed portions of barrier layer exposing a part of the trench fill polysilicon surface and leaving the doped, remainder of the amorphous silicon masking layer exposed. Counterdope the exposed part of the trench fill material. Oxidize exposed portions of the polysilicon trench fill material, and then strip the remainder of the masking layer.

    摘要: A method for forming substantially uniformly thick, thermally grown, silicon dioxide material on a silicon body independent of bon axis. A trench is formed in a surface of the silicon body, such trench having sidewalls disposed in different crystallographic planes, one of such planes being the crystallographic plane and another one of such planes being the plane. A substantially uniform layer of silicon nitride is formed on the sidewalls. The trench, with the with substantially uniform layer of silicon nitride, is subjected to a silicon oxidation environment with sidewalls in the plane being oxidized at a higher rate than sidewalls in the plane producing silicon dioxide on the silicon nitride layer having thickness over the plane greater than over the plane. The silicon dioxide is subjected to an etch to selectively remove silicon dioxide while leaving substantially un-etched silicon nitride to thereby remove portions of the silicon dioxide over the plane and to thereby expose underlying portions of the silicon nitride material while leaving portions of the silicon dioxide over the plane on underlying portions of the silicon nitride material. Exposed portions of the silicon nitride material are selectively removed to expose underlying portions of the sidewalls of the trench disposed in the plane while leaving substantially un-etched portions of the silicon nitride material disposed on sidewalls of the trench disposed in the plane. The structure is then subjected to an silicon oxidation environment to produce the substantially uniform silicon dioxide layer on the sidewalls of the trench.
