Abstract
A first metal surface of a first article of metal, such as the metalization layer on a silicon semiconductor device, is bonded to an opposing or second metal surface of a second article of metal, such as a 'structured copper' strain buffer, using an improved method of thermo-compression diffusion bonding that involves temperature control independent of compressional force control, whereby a superior bond is obtained.
