    Abstract: THE PRESENT INVENTION DISCLOSES AN INTERCONNECTION STRUCTURE (50) FOR PROVIDING ELECTRICAL COMMUNICATION WITH AN ELECTRONIC DEVICE (66) WHICH INCLUDES A BODY THAT IS FORMED SUBSTANTIALLY OF COPPER AND A SEED LAYER (76,78,86) OF EITHER A COPPER ALLOY OR A MTEAL THAT DOES NOT CONTAIN COPPER SANDWICH ED BETWEEN THE COPPER CONDUCTOR BODY AND THE ELECTRONIC DEVICE FOR IMPROVING THE ELETROMIGRATION RESISTANCE, THE ADHESION PROPERTY AND OTHER SURFACE PRORPERTIES OF THE INTERCONNECTION STRUCTURE. THE PRESENT INVENTION ALSO DISCLOSES, METHODS FOR FORMING AN INTERCONNECTION STRUCTURE (50) FOR PROVIDING ELECTRICAL CONNECTIONS TO AN ELECTRONIC DEVICE (66) BY FIRST DEPOSITING A SEED LAYER (76,78,86) OF COPPER ALLOY OR OTHER METAL THAT DOES NOT CONTAIN COPPER ON AN ELECTRONIC DEVICE, AND THEN FORMING A COPPER CONDUCTOR BODY ON THE SEED LAYER INTIMATELY BONDING TO THE LAYER SUCH THAT ELECTROMIGRATION RESISTANCE, ADHESION AND OTHER SURFACE PROPERTIES OF THE INTERCONNECTION STRUCTURE ARE IMPROVED.(FIG 2)

    Abstract: A method for increasing an electrical resistance of a resistor that is within a semiconductor structure. A fraction of a surface layer of the resistor is oxidized with oxygen particles. In an embodiment, the fraction of the surface layer is heated by a beam of particles, such that the semiconductor structure is within a chamber that includes the oxygen particles as gaseous oxygen-comprising molecules. In an embodiment, the semiconductor structure is immersed in a chemical solution which includes the oxygen particles, wherein the oxygen particles includes oxygen-comprising liquid molecules, oxygen ions, or an oxygen-comprising gas dissolved in the chemical solution under pressurization. In an embodiment, the resistor is tested to determine whether the electrical resistance of the resistor after being oxidized with the oxygen particles is within a tolerance of a predetermined target resistance.
