Claim Text:
1. A method of fabricating a composite device for splitting photonic functions between two or more materials, the method comprising: aligning a first mask with a target; etching a recess in a platform based on the first mask aligned with the target; bonding a chip to the platform, wherein: applying a contact metal on top of the chip; at least partially covering both the platform and the chip with a first material, thus filling the gap; applying a second mask that defines an area to etch over the gap; partially removing first material in the gap based on the second mask defining the area to etch over the gap; at least partially filling the gap with a second material; removing a portion of the second material from the gap; at least partially covering both the platform and the chip with a third material; applying a third mask to define an area to remove from the chip to form a feature on the chip; removing material from the chip to form the feature on the chip; and covering the chip with a fourth material.
