    Abstract: In accordance with the present invention, the active rectifier is a circuit which directly takes the place of a passive rectifier by using a switching module (or simply a device in cases where a single device is used) controlled by a sensing circuit. Where passive devices have a single knee value determined by the physical properties of the semi-conductive material being used, the active circuit can be designed to a range of knee voltages and other performance criterion. Additional flexibility is available to the designer through the active rectifiers ability to allow for manipulation of the curve of response from the circuit in the knee region. Flexibility both in production, in designs, and in characteristics make the active rectifier highly valuable for engineering firms designing larger electronic circuits.

    Abstract: A charged particle beam performance measurement system includes a charged particle beam generator device for producing a charged particle beam, a test reticle having at least two areas of higher transparency than its surroundings that form a pattern, a reduction projection imaging device, a reference target having an essentially identical pattern as the test reticle, and a beam current detector. A patterned beam is generated by passing the charged particle beam through the pattern areas of the test reticle. The patterned beam is reduced and projected by the reduction projection imaging device and the reduced patterned beam is imaged onto a reference target. The reduced patterned beam is then exposed to the reference target, wherein some of the beam may pass through reference target pattern areas. Beam current detector records and measures the amount of beam current that is absorbed on, back-scattered from, or transmitted by the target reference, and determines from the measured beam current the accuracy of the projection system.

    Abstract: A lithographic projection method which comprises projecting radiation along a transmission path and through a lens system and an opaque back focal plane filter for electrons with a transparent aperture for the projected radiation to produce a patterned image and an amount of desired radiation on a target. The transmission path includes a source of radiation of charged particles directed at a target comprising a substrate coated with resist. A pattern-defining mask that contains a plurality of subresolution scattering features thereon to produce the desired degree of scattering of the radiation is placed between the source and the target. The subresolution scattering features vary in density as an direct function of predicted proximity exposure.

    Abstract: A method and system for studying the effect of electron-electron interaction in an electron beam writing system. First and second test reticles are provided that have different open areas. An electron beam is directed through the first test reticle to form a first pattern on a test surface, and the electron beam is then directed through the second test reticle to form a second pattern on a test surface. Because the open areas of the test reticles differ, the current of the electron beam is different when that beam passes through the first test reticle than when that beam passes through the second test reticle. The resolution of the first formed pattern is compared with the resolution of the second formed pattern to assess the effect of the different currents of the electron beam on the resolutions of the formed patterns.
