摘要： A method for calibrating a laser micro-machining system in three dimensions includes scanning a sample workpiece to determine the 3D surface, calculating the best fit surfaces to the scanned data in a series of steps, and storing the results so that subsequent workpieces can be calibrated to remove systematic errors introduced by variations in an associated material handling subsystem. The method optionally uses plate bending theory to model particulate contamination and splines to fit the 3D surface in a piecewise fashion to minimize the effect of local variations on the entire surface fit.

摘要： Methods and systems selectively irradiate structures on or within a semiconductor substrate using a plurality of laser beams. The structures are arranged in a row extending in a generally lengthwise direction. The method generates a first laser beam that propagates along a first laser beam axis that intersects the semiconductor substrate and a second laser beam that propagates along a second laser beam axis that intersects the semiconductor substrate. The method simultaneously directs the first and second laser beams onto distinct first and second structures in the row. The method moves the first and second laser beam axes relative to the semiconductor substrate substantially in unison in a direction substantially parallel to the lengthwise direction of the row, so as to selectively irradiate structures in the row with one or more of the first and second laser beams simultaneously.

摘要： Laser beam positioners (300, 340) employ a steering mirror (236, 306) that performs small-angle deflection of a laser beam (270) to compensate for cross-axis (110) settling errors of a positioner stage (302). A two-axis mirror is preferred because either axis of the positioner stages may be used for performing work. In one embodiment, the steering mirror is used for error correction only without necessarily requiring coordination with the positioner stage position commands. A fast steering mirror employing a flexure mechanism and piezoelectric actuators to tip and tilt the mirror is preferred in semiconductor link processing (“SLP”) applications. This invention compensates for cross-axis settling time, resulting in increased SLP system throughput and accuracy while simplifying complexity of the positioner stages because the steering mirror corrections relax the positioner stage servo driving requirements.
摘要翻译：激光束定位器（300,340）使用执行激光束（270）的小角度偏转以补偿定位器台（302）的横轴（110）沉降误差的转向镜（236,306）。优选两轴镜，因为定位器台的任一轴可用于执行作业。在一个实施例中，导向镜仅用于纠错，而不需要与定位器台位置命令协调。在半导体连接处理（“SLP”）应用中，优选采用挠曲机构的快速转向镜和压电致动器来使倾斜反射镜。本发明补偿横轴建立时间，从而提高了SLP系统的吞吐量和精度，同时简化了定位器台的复杂性，因为导向镜校正放松了定位器级的伺服驱动要求。

摘要： A method makes a discrete adjustment to static alignment of a laser beam in a machine for selectively irradiating conductive links on or within a semiconductor substrate using the laser beam. The laser beam propagates along a beam path having an axis extending from a laser to a laser beam spot at a location on or within the semiconductor substrate. The method generates, based on at least one measured characteristic of the laser beam, at least one signal to control an adjustable optical element of the machine effecting the laser beam path. The method also sends said at least one signal to the adjustable optical element. The method then adjusts the adjustable optical element in response to said at least one signal so as to improve static alignment of the laser beam path axis.

摘要： Methods and systems selectively irradiate electrically conductive structures on or within a semiconductor substrate using multiple laser beams. The structures are arranged in a plurality of substantially parallel rows extending in a generally lengthwise direction. One method propagates a first laser beam along a first propagation path having a first axis incident at a first location on or within the semiconductor substrate at a given time. The first location is either on a structure in a first row of structures or between two adjacent structures in the first row. The method also propagates a second laser beam along a second propagation path having a second axis incident at a second location on or within the semiconductor substrate at the given time. The second location is either on a structure in a second row of structures or between two adjacent structures in the second row. The second row is distinct from the first row, and the second location is offset from the first location by some amount in the lengthwise direction of the rows. The method moves the first and second laser beam axes substantially in unison in the lengthwise direction of the rows relative to the semiconductor substrate, so as to selectively irradiate structures in the first and second rows with the first and second laser beams respectively.
