Abstract:
1. A method for encapsulating a device with a seal comprising: forming a first layer of a first metal on at least one of a first substrate and a second substrate; forming a second layer of a second metal adjacent to the first layer of the first metal, wherein the second metal has a lower melting point than the first metal; forming at least one raised feature protruding from a bonding surface and into at least one of the first layer and the second layer; forming a wetting layer of an organic material on at least one of the first substrate and the second substrate and adjacent to the second layer of the lower melting point second metal, and bonding the first substrate and the second substrate with a bondline of an alloy formed from the first metal and the second metal wherein the wetting layer is entirely driven off by evaporation at a temperature of alloy formation.
