Abstract:
1. A system comprising: a first chamber, the first chamber being under vacuum and configured to receive a first substrate for processing, the first chamber housing therein: a printing system disposed within the first chamber, the printing system configured to deposit on the first substrate a pattern or shape indicating where solder is to be placed; and a deposition system configured to deposit solder, to the pattern or shape, outwardly from the substrate; and a plasma/bonding chamber in operable communication with the first chamber, the plasma/bonding chamber comprising a plurality of walls defining an interior space that is substantially scaled from an environment external to the plasma/bonding chamber, wherein the interior space is constructed and arranged for receiving a second substrate and for receiving the first substrate, to be plasma cleaned, capped, and bonded to the second substrate; a plasma cleaning system disposed and operating within the interior space of the plasma/bonding chamber, the plasma cleaning system in operable communication with a capping system and a bonding system that are each disposed within and operable within the plasma/bonding chamber, the plasma cleaning system comprising a gas input for receiving at least one plasma gas, at least one electrode for plasma generation, and a vacuum pump to create a vacuum in the plasma/bonding chamber, wherein the plasma cleaning system is configured to plasma clean the first substrate while both the plasma cleaning system and the bonding system are operably coupled to and disposed within the interior space of the plasma/bonding chamber, wherein the plasma cleaning system is constructed and arranged for receiving the first substrate for plasma cleaning of the first substrate, under vacuum, for a first time when the first substrate is received into the plasma bonding chamber and for receiving the first substrate for cleaning a second time, after the first substrate has had a capping layer applied to it; a capping layer deposition system disposed and operating within the interior space of the plasma/bonding chamber, the capping layer deposition system in operable communication with the plasma cleaning system and constructed and arranged to deposit a capping layer of a material resistant to oxidation to the first substrate after the first substrate has been processed by the plasma cleaning system; and a bonding system disposed and operating within the same interior space of the plasma/bonding chamber in which the plasma cleaning system operates, the bonding system being in operable communication with the capping layer deposition system and comprising a support to support at least a first substrate to be bonded and at least one bonding plate operable to bond the first substrate to the second substrate; wherein the bonding system is configured to receive the first substrate after the first substrate has been capped and plasma cleaned a second time and, after the first substrate has been aligned to the second substrate, to bond the first substrate to the second substrate, under vacuum conditions, while the first and second substrates are disposed within the same interior space as the plasma system.
