Abstract: A mounting head includes a first pivot assembly and a second pivot assembly. The first pivot assembly may be configured to pivot a platform of the mounting head about a first axis, and the second pivot assembly may be configured to pivot the platform about a second axis. A pivot assembly may comprise a threaded shaft having an attachment element configured to move linearly along the axial length of the threaded shaft as the threaded shaft is rotated. The linear movement of the attachment element may drive pivotal movement of the platform. The mounting head may further include position indicators, configured for indicating, in linear coordinates, the position of the platform. Methods of using and adjusting a mounting head are disclosed.

Abstract: A method for fabricating a contact of a semiconductor device structure includes forming a barrier layer that is entirely recessed within a contact aperture. A central region of the barrier layer may be recessed relative to at least a portion of an outer periphery of the barrier layer. Semiconductor device structures including such contacts are also disclosed. Such a contact may be part of a memory cell.

Abstract: A high surface area capacitor structure includes a storage electrode with recesses. An upper surface of the storage electrode has a maze-like appearance. Low elevation regions of a hemispherical grain polysilicon layer may remain on the upper surface of the storage electrode. The storage electrode or portions thereof may be lined or coated with dielectric material. The dielectric material may space a cell electrode of the high surface area capacitor structure apart from the storage electrode. One or both of the storage electrode and the cell electrode may be formed from polysilicon. Intermediate structures, which include mask material over contiguous low elevation regions of a layer of hemispherical grain polysilicon, which may have a maze-like appearance, and apertures located laterally between the low elevation regions of the layer of hemispherical grain polysilicon, are also disclosed.

Abstract: A high dielectric constant memory cell capacitor and method for producing the same, wherein the memory cell capacitor utilizes relatively large surface area conductive structures of thin spacer width pillars or having edges without sharp corners that lead to electric field breakdown of the high dielectric constant material. The combination of high dielectric constant material in a memory cell along with a relatively large surface area conductive structure is achieved through the use of a buffer material as caps on the thin edge surfaces of the relatively large surface area conductive structures to dampen or eliminate the intense electric field which would be generated at the corners of the structures during the operation of the memory cell capacitor had the caps not been present.
