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.

摘要： An apparatus and method for physically separating non-metallic substrates by forming a microcrack in the substrate and controllingly propagating the microcrack. An initial mechanical or pulsed laser scribing device forms a microcrack in the substrate. A scribe beam is applied onto the substrate on a separation line. A coolant stream intersects with, or is adjacent to, the trailing edge of the scribe beam. The temperature differential between the heat affected zone of the substrate and the coolant stream propagates the microcrack. Two breaking beams on opposing sides of the separation line follow the coolant stream. The breaking beams create controlled tensile forces that extend the crack to the bottom surface of the substrate for full separation. The scribe and break beams and coolant stream are simultaneously moved relative to the substrate. A preheat beam preheats the heat affected area on the substrate. The beams are formed by an arrangement of lasers and mirrors and lenses. A movable mirror selectively diverts a beam to form either the preheat beam or one or more of the break and scribe beams. Spherical aberration is introduced in the break and scribe beams to flatten their energy distribution profiles and evenly apply the beam energy. A supplemental mechanical force, applied by vertically movable wheels or by restraining the substrate against a curved frame, creates a bending moment to facilitate the separation process.
