ROOM TEMPERATURE DIRECT METAL-METAL BONDING

摘要

A method for forming direct metal-metal bond between metallic surfaces is disclosed. The method comprises depositing a first nanostructured organic coating (118) on a first metallic surface (116) to form a first passivation layer thereon, the first nanostructured organic coating (118) comprising an organic phase with nanoparticles dispersed within the organic phase, contacting the first nanostructured organic coating (118) with a second metallic surface (126), and applying on the first and second metallic surfaces (116, 126) at least a bonding temperature of at least room temperature and/or a bonding pressure for a bonding period to bond the first and second metallic surfaces (116, 126) thereby forming the direct metal-metal bond therebetween. A second nanostructured organic coating (128) comprising an organic phase with nanoparticles dispersed within the organic phase may also be deposited on the second metallic surface (126).
