Patent ID: 8049135

Claim:
A method for making 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 propagating 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 comprising: generating, 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; sending said at least one signal to the adjustable optical element; and adjusting the adjustable optical element in response to said at least one signal and thereby altering the laser beam path axis so as to improve static alignment of the laser beam path, wherein the laser beam path is aligned on a dimensional scale comparable to the conductive links on or within the semiconductor substrate such that the laser beam can irradiate selected conductive links.
