Abstract
Official abstract text for this publication.
A method includes generating a laser beam and applying the beam to a substrate to form a via in the substrate. The laser beam has an intensity profile taken at a cross-section transverse to the direction of propagation of the beam. The intensity profile has a first substantially uniform level across an interior region of the cross-section and a second substantially uniform level across an exterior region of the cross-section. The second intensity level is greater than the first intensity level.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: generating a laser beam; shaping the laser beam with an optical element such that the laser beam has an intensity profile taken at a cross-section transverse to a direction of propagation of the beam, the intensity profile having a first substantially uniform level across an interior region of said cross-section, and having a second substantially uniform level across an exterior region of said cross-section, said second level greater t…
