A 3-dimensional opto-electronic system employs an optical communications channel between spaced circuit substrates. The beam from an in-line laser on one substrate is deflected by a turning mirror that is monolithically integrated on the substrate along with the laser and its associated electronic circuitry, and directed to an optical detector on another substrate. The deflection is accomplished with a turning mirror that is specially fabricated with a focused ion beam (FIB) so that it focuses or collimates as well as deflects the laser beam onto the photodetector. The mirror is initially formed with a flat surface, and is thereafter processed with the FIB to produce focusing curvatures in both x and y directions. The mirror is preferably spaced away from the laser, and is illuminated over substantially the full laser height to maximize its focal length for a given reflected spot size. For a rectangular laser beam, the mirror curvature can be different along the mirror width than along its height to produce a smaller, more rounded spot. The mirror curvature is preferably established by raster scanning the mirror area in multiple series of FIB scans, with each series encompassing a different proportion of the mirror surface, and repeating each series a number of times that generally increases with its area. The area-dependent repetition pattern is preferably followed for two sets of scans, one with the scanning area's x dimension progressively reduced and the other with its y dimension progressively reduced.

A fluid operated overshot with an outer metal mandrel internally supports a resilient internal sleeve. The sleeve telescopes over a fish to grip the fish on expanding radially inwardly. This expansion is fluid powered by applying a force to the inner sleeve to expand inwardly from a piston which compresses the sleeve, or form surrounding the inner sleeve in a concentric fluid receiving cavity.

A secondary ion collection and transport system, for use with an ion microprobe, which is very compact and occupies only a small working distance, thereby enabling the primary ion beam to have a short focal length and high resolution. Ions sputtered from the target surface by the primary beam's impact are collected between two arcuate members having radii of curvature and applied voltages that cause only ions within a specified energy band to be collected. The collected ions are accelerated and focused in a transport section consisting of a plurality of spaced conductive members which are coaxial with and distributed along the desired ion path. Relatively high voltages are applied to alternate transport sections to produce accelerating electric fields sufficient to transport the ions through the section to an ion mass analyzer, while lower voltages are applied to the other transport sections to focus the ions and bring their velocity to a level compatible with the analyzing apparatus.

The separated ion source combines an ion source and a magnetic mass separator within a single magnetic field geometry. The preferred ion source has a low voltage Penning discharge configuration and produces a charged particle beam in the form of a ribbon with a rectangular cross section.

Separated ion source

A high current ion beam is extracted from an ion plasma by a low perveance ion optical system including a screen electrode, a final electrode and an intermediate electrode therebetween which is shaped to correspond to the extraction voltage equipotentials therebetween. By controlling the voltage of the intermediate electrode with respect to the other two electrodes focusing is accomplished.

The linearity of a field-effect transistor's logarithmic transconductance extended over an increased range by having its channel non-uniformly doped in a direction along the width of the gate electrode and perpendicular to that of current flow.
