Abstract
The present invention includes a method for bonding one semiconductor surface to a second semiconductor surface. The method includes providing a first article that has a semiconductor surface and a second article that has a semiconductor surface. The semiconductor surfaces are annealed with an energy source wherein energy is confined to the semiconductor surfaces. The annealed surfaces are bonded to each other.
