Abstract
The present disclosure relates to the field of fabricating microelectronic packages, wherein cavities are formed in a dielectric layer deposited on a first substrate to maintain separation between soldered interconnections. In one embodiment, the cavities may have sloped sidewalls. In another embodiment, a solder paste may be deposited in the cavities and upon heating solder structures may be formed. In other embodiments, the solder structures may be placed in the cavities or may be formed on a second substrate to which the first substrate may be connected. In still other embodiments, solder structures may be formed on both the first substrate and a second substrate. The solder structures may be used to form solder interconnects by contact and reflow with either contact lands or solder structures on a second substrate.
