Method and apparatus for aligning a laser diode on a slider

摘要

A structure includes a channel waveguide and a pocket adjacent to an input facet of the channel waveguide. A laser having an output facet is positioned in the pocket. The structure includes a stop on either the laser or a wall of the pocket. The stop is positioned at an interface between the laser and the wall of the pocket such that the output facet of the laser and the input facet of the waveguide are separated by a gap.

1. A method comprising:
positioning a carrier wafer relative to a head wafer such that each of a plurality of lasers of the carrier wafer is aligned with an alignment feature of a corresponding one of a plurality of slider portions of the head wafer; injecting a gas between the carrier wafer and the head wafer via openings in at least one the carrier wafer and the head wafer to create preferential surface conditions on solder surfaces therebetween; and performing a reflow operation to bond the lasers to the corresponding slider portions, wherein the reflow operation further causes a final alignment therebetween in cooperation with the alignment features of the slider portions.
