    Abstract: The present invention relates to methods of predicting proximity heating in real-time as the writing proceeds enabling beam compensation to be performed in real-time. Particular attention is given to vector scanning in which the pattern of writing does not follow prescribed kinematics, but the writing tends to cluster into cells. A library of standard cells is constructed. As writing of the pattern proceeds, the individual flashes are agglomerated into cells that are compared with standard cells to determine proximity heating in the resist as a function of the distance of the previously written cells from the point of present writing, and the elapsed time since writing a previously written cell. Present writing snaps to a sufficiently coarse space-time grid to limit the computational burden but fine enough the represent variations in temperature over space and time. Further agglomeration of cells into super-cells, super-super-cells, etc. are also described. An advantage of the present technique is its applicability to vector scanning and to stenciling techniques for writing patterns on the wafer surface, not dependent on foreknowledge of a particular pattern of writing, as is the case for raster or serpentine scanning.

    Abstract: The invention is concerned with a float-operated electrical switch assembly comprising a vertical tubular housing, at least the lower end of which is arranged to be open to a liquid the level of which is to be monitored. A float is restrained to move vertically in the housing with changes in the liquid level and a magnet mounted on the float cooperates with a magnetically responsive switch actuator which is contained in a tubular casing of non-magnetic material extending into the housing from the side of the housing. The switch assembly is primarily intended for a low level alarm.

    Abstract: A laser beam or other parallel light beam divides at a beamsplitter into sample and reference beams. The sample beam reflects from a reflective surface back to the beamsplitter, and the reference beam reflects from a retroreflector back to the beamsplitter. The beams are then directed into a telescope. The angle between sample and reference beams at the telescope is proportional to the angle between the laser beam and the normal to the reflective surface. The telescope collects both sample beam and reference beam and transforms each beam into a sharply defined point image. The lateral separation between the two point images is proportional to the magnification of the telescope and to the angle formed at the telescope between the sample beam and the reference beam. If the reflective surface is accurately aligned relative to the laser beam, then the two point images are substantially superposed on one another. Alignment is performed by adjusting the orientation of the reflective surface, until the lateral separation between the two point images reaches zero or a predetermined value.

    Abstract: An electron beam pattern generating system for exposing a pattern on a substrate using a raster scan method. The system stores a rasterized representation of the pattern as a plurality of regular pixel dose exposure levels. These pixel dose exposure levels are evaluated by the system for one or more proximity effects and corrections to the dose exposure level and/or pixel location are calculated. The system includes apparatus for both calculation and storage of intermediate and final results as required. As they are calculated, the corrections are provided to an exposure dose modulator wherein they are applied to forming the pattern. Thus corrections for both long range and short range proximity effects due to both electron scattering and heating as well as for proximity effects due to global thermal expansion can be calculated and provided during run-time and a corrected pattern exposed.

    Abstract: A digitally controlled platform for precise celestial tracking of astronomical telescopes, generally those having an independent pointing mechanism. A movable stage carrying the telescope is moved relative to a base by three digitally controlled actuators each of which determines the distance between a point fixed in the base and a point fixed stage. The base and stage otherwise are connected by a mechanism that holds a single point fixed in the base in coincidence with a single point fixed in the stage. It functions without approximation at any digitally specified latitude and longitude, enabling astrophotography with alt/azimuth mounted telescopes and diurnal tracking through the zenith. The digital controller may be a personal computer laptop running a multitasking operating system linked to the platform electronics by a Universal Serial Bus cable. Novel software design allows precise tracking, control, and calibration in spite of operating system and Universal Serial Bus latency.
