    摘要: An improved method of forming seed openings for zone-melting and recrystallization of polysilicon film on an insulator over silicon (SOI) is described. This method comprises forming a narrow discontinuous pattern of seed openings formed by an overlapping sub-pattern of discontinuous shaped openings. Alternatively, in an edge bead seed embodiment, a resist is removed from an SOI precursor structure, comprising an insulator on an Si wafer, thus exposing the peripheral edge of the insulator. The exposed insulator is then also removed to provide a peripheral edge seed opening to the underlying Si wafer.

    摘要: A binocular viewing system provides images from electronic display elements to the left and right eyes of a user transmitted via right eye and left eye display assemblies connected by a nose bridging element. The binocular viewing system includes an interpupillary distance adjustment mechanism to accommodate multiple users. Accommodation for vision correction and a focus mechanism may also be provided. Also, the binocular viewing system provides a virtual image at a distance less than infinity, in an arrangement that also accommodates a range of interpupillary distances. In other aspects, the binocular viewing system incorporates face curvature to more comfortably fit a user's head, and places the electronic display elements close to the user's eye, either in the line of sight, or within the nose bridging element.
