ABSTRACT:
A method for enhancing the bond energy of reaction bonded surfaces in which polished (10) and cleaned surfaces (12) are bombarded with oxygen ions, fluorine ions or a mixture of oxygen and fluorine ions (14) to activate these surfaces. The activated surfaces are then cleaned to remove particulates (15) and then contacted (16) at room temperature to make a reaction bond therebetween. The reaction bond may be heated (18) to further increase the bond energy. The bond energy of oxygen ion bombarded surfaces can have two times the bond energy of surfaces subject to a conventional bonding process. The addition of fluorine ions to the oxygen ions used to activate the surfaces can further increase the bond energy between the contacted surfaces by at least another factor of 2.
