摘要： A precision, laser-based method and system for high-speed, sequential processing of material of targets within a field are disclosed that control the irradiation distribution pattern of imaged spots. For each spot, a laser beam is incident on a first anamorphic optical device and a second anamorphic optical device so that the beam is controllably modified into an elliptical irradiance pattern. The modified beam is propagated through a scanning optical system with an objective lens to image a controlled elliptical spot on the target. In one embodiment, the relative orientations of the devices along an optical axis are controlled to modify the beam irradiance pattern to obtain an elliptical shape while the absolute orientation of the devices controls the orientation of the elliptical spot.

摘要： In an optical-radiation patterning apparatus, a scan mirror (29) so deflects laser light from a source (32) as to draw a pattern on a substrate (26). A focusing system (42) forms a light spot on the substrate that is significantly narrower than the line to be drawn, and it thereby minimizes the sensitivity of the line-edge position to variations in light-spot size. To achieve the intended line width, an acousto-optical device (32) introduces dither in the direction orthogonal to the light-spot motion that the scan mirror (30) causes. The focusing system (42) shapes the spot so that it is wider in the scan direction than it is in the dither direction, and this permits a relatively high scan rate for a given dither frequency.

摘要： A system including confocal and triangulation-based scanners or subsystems provides data which is both acquired and processed under the control of a control algorithm to obtain information such as dimensional information about microscopic targets which may be “non-cooperative.” The “non-cooperative” targets are illuminated with a scanning beam of electromagnetic radiation such as laser light incident from a first direction. A confocal detector of the electromagnetic radiation is placed at a first location for receiving reflected radiation which is substantially optically collinear with the incident beam of electromagnetic radiation. The system includes a spatial filter for attenuating background energy. The triangulation-based subsystem also includes a detector of electromagnetic radiation which is placed at a second location which is non-collinear with respect to the incident beam. This detector has a position sensitive axis. Digital data is derived from signals produced by the detectors. In this way, data from at least one triangulation-based channel is acquired in parallel or sequentially with at least one slice of confocal image data having substantially perfect temporal and spatial registration with the triangulation-based sensor data. This allows for fusion or further processing of the data for use with a predetermined measurement algorithm to thereby obtain information about the targets.
