Laser via drilling apparatus and methods |
摘要 |
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. |

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 than said first level; and applying the shaped laser beam to a substrate to form a via in the substrate. |
