Abstract: A semiconductor device includes a semiconductor substrate having a first region and a second region, insulators, gate stacks, and first and second S/Ds. The first and second regions respectively includes at least one first semiconductor fin and at least one second semiconductor fin. A width of a middle portion of the first semiconductor fin is equal to widths of end portions of the first semiconductor fin. A width of a middle portion of the second semiconductor fin is smaller than widths of end portions of the second semiconductor fin. The insulators are disposed on the semiconductor substrate. The first and second semiconductor fins are sandwiched by the insulators. The gate stacks are over a portion of the first semiconductor fin and a portion of the second semiconductor fin. The first and second S/Ds respectively covers another portion of the first semiconductor fin and another portion of the second semiconductor fin.

Abstract: Semiconductor structures are provided. The semiconductor structure includes a substrate and nanostructures formed over the substrate. The semiconductor structure further includes a gate structure surrounding the nanostructures and a source/drain structure attached to the nanostructures. The semiconductor structure further includes a contact formed over the source/drain structure and extending into the source/drain structure.

Abstract: Methods, apparatus, and system for a virtual reality device including a display monitor, an adjustable lens, and a focus sensor. The focus sensor may be used to measure a distance between an eye and the display monitor or whether the eye is able to focus images from the display monitor. The user may provide a diopter correction. The VR device may then adjust an optical power of the adjustable lens, based on at least one of the distance or whether the eye is able to focus images from the display monitor. The focus sensor may emit coded electromagnetic radiation and determine a time-of-flight of the coded electromagnetic radiation to determine the distance or whether the eye is able to focus images from the display monitor. The adjustable lens may comprise a flexible lens; the flexible lens may be adjusted with actuators, such as piezoelectric actuators.

Abstract: A barrier film includes at least one laminate to be disposed on a substrate. The laminate includes a modifying layer proximate to the substrate and at least one multi-layered barrier unit disposed on the modifying layer. The multi-layered barrier unit includes an aluminum oxide layer, a silicon oxide layer, and a zirconium oxide layer laminated to one another.
