    摘要: A coaxial laser targeting device is provided for use with x-ray equipment. The device includes an x-ray transparent housing, which encloses a gimbal platform that may be adjustably inclined in any direction. A laser source supplies light through an optical fiber to a lens assembly in the center of the gimbal platform and directs light through a laser emitting aperture in the housing. Three adjustment members arranged in a triangular configuration are used to incline the gimbal platform in any direction relative to the housing to angularly align the laser beam with an x-ray beam emitted by the x-ray equipment so that the beams are coaxial. A visible target created by the laser beam on a patient allows surgeons and the like to accurately perform medical operations without the need to continually operate an x-ray machine.

    摘要: A method for forming an emitter tip for use in a field emission device. An emitter layer is provided over a substrate. The emitter layer is overlaid with a blanket dielectric which is in turn overlaid by a masking layer. In a first etching operation, a masking island and an underlying dielectric island are formed from the masking layer and the blanket dielectric, respectively. These islands serve as a masking structure during subsequent etching processes by which an emitter tip is formed from the emitter layer. Accordingly, a second etching operation is conducted, whereby an etch chemistry which exhibits both isotropic and anisotropic characteristics is used to remove a portion of the emitter layer by undercutting beneath the masking structure. A third etching operation is conducted, wherein the etch chemistry is substantially more anisotropic than the etch chemistry of the second etching operation. The second and third etches mobilize a portion of the masking layer and form an emitter tip from the emitter layer. The emitter tip has a substantially rectilinear vertical profile.
