Abstract:
1. A method of bonding substrates, comprising: directly contacting a first non-metallic region proximate to a first plurality of metallic pads disposed on a first substrate with a second non-metallic region proximate to a plurality of metallic structures disposed on a second substrate; after directly contacting the first and second non-metallic regions, bonding the first non-metallic region to the second non-metallic region without applying external pressure; forming a contact between a first pad of the first plurality of metallic pads with a first structure of the plurality of metallic structures and generating pressure between the first pad and the first structure during said bonding the first non-metallic region to the second non-metallic region; and heating the first and second substrates in a range of about 100-250° C.
