Patent number: 6670570
Abstract: A method of treating an object containing a material of metal, oxidized metal, non-metal, and the like and combinations thereof. The method includes (a) exposing an object to a controlled gas atmosphere, and (b) during at least a portion of time during such exposing, subjecting a specific area of the material to an energy beam, preferably a focused energy beam, more preferably a focused and filtered energy beam, having sufficient intensity to provide for the treating of the specific area. Such treating includes heating, welding, cutting, dicing, soldering, singulating, reducing, oxidizing, fusing, melting, and the like and combinations thereof. The energy beam source can be a laser selected from a group which includes YAG lasers, excimer lasers, gas lasers, semiconductor lasers, solid-state lasers, dye lasers, X-ray lasers, free-electron lasers, ion lasers, gas mixture lasers, chemical lasers, and the like and combinations thereof.
