Claim Text:
1. A bonding method, comprising: forming a first plurality of metallic pads in a first insulating layer; forming a second plurality of metallic pads in a second insulating layer; polishing the first and second insulating layers having the first and second pluralities of metallic pads formed therein, respectively; directly contacting the first insulating layer with the second insulating layer; after directly contacting the first and second insulating layers, chemically bonding the first insulating layer to the second insulating layer without applying external pressure; after directly contacting the first and second insulating layers, generating internal pressure, without applying external pressure, between the first plurality of metallic pads and the second plurality of metallic pads to form a contact between a first metallic pad of the first plurality of metallic pads and a second metallic pad of the second plurality of metallic pads.
