  • Patent number: 6570155
    Abstract: The present invention relates to bi-directional raster scanning (“serpentine scanning”) for an electron beam lithography system. Improved circuit components are described for generating the true triangular waveform required in bi-directional scanning. The circuitry of the present invention provides control of signal amplitude, frequency and phase to better than 1 ppm by making use of signal generation circuitry described pursuant to the present invention. A series of coarse and fine tuning delay adjustments pursuant to the present invention accommodate a variety of operating conditions. Another embodiment of the present invention relates to an optimization of the data path hardware for bi-directional scanning, including isolating a section of the data path hardware specifically to provide calibration scans. The delay circuit built into the data preparation hardware helps compensate for delays caused by finite bandwidth in the analogue drivers.

  • Patent number: 6246190
    Abstract: An electron gun assembly which integrates electronics required to power the electron gun and the electron gun itself in one module in a high voltage operating environment. The assembly has four major sections: interface cables; electronic circuits (active and high voltage); the electron emitter; and a mechanical enclosure for the assembly. The electronics portion of the assembly has two distinct sections: an active electronics section (which contains digital to analog converters, interface to a control computer, and analog outputs terminals to control the high voltage electronics) and a high voltage electronics section (which contains high-voltage multiplying circuits and feedback and filtering elements). These two sections are electrically connected and are present within an internal box at one end of the assembly, or alternately, the high voltage electronics section is disposed below the active electronics section and outside the internal box.
