CARRIER SUBSTRATE FOR MICRO DEVICE PACKAGING

摘要

A carrier substrate (100) with laser sources includes a transparent center substrate (20), an upper substrate (30) adhered to the center substrate having openings (40) formed therein to expose the center substrate on a first side, and a lower substrate (32) adhered to the center substrate on a second side opposite the first side and having openings (42) formed therein to expose the center substrate on the second side, the openings on the lower substrate corresponding to positions of the openings in the upper substrate. Frequency conversion elements (60) are disposed on the center substrate within the openings of the lower substrate. Laser dies (70) are aligned to the frequency conversion elements and coupled to the lower substrate to provide light though the frequency conversion elements and the center substrate during operation. Methods for fabrication are also disclosed.
