    摘要: In one aspect the invention provides a method for laser induced breakdown of a material with a pulsed laser beam where the material is characterized by a relationship of fluence breakdown threshold (Fth) versus laser beam pulse width (T) that exhibits an abrupt, rapid, and distinct change or at least a clearly detectable and distinct change in slope at a predetermined laser pulse width value. The method comprises generating a beam of laser pulses in which each pulse has a pulse width equal to or less than the predetermined laser pulse width value. The beam is focused to a point at or beneath the surface of a material where laser induced breakdown is desired. The beam may be used in combination with a mask in the beam path. The beam or mask may be moved in the x, y, and Z directions to produce desired features. The technique can produce features smaller than the spot size and Rayleigh range due to enhanced damage threshold accuracy in the short pulse regime.

    摘要: A silicon on insulator structure and method of making the structure. A high purity, substantially defect free silicon wafer is the basis for forming a final thin silicon layer on an insulator layer, the silicon having substantially the same chemical and structural state as the starting silicon wafer. Dopant atoms of MeV energy range are implanted into the silicon wafer, the silicon wafer having an insulator layer coupled thereto; and an underlying silicon carrier wafer is coupled to the insulator. The implanted silicon wafer undergoes preferential etch stop removal of the silicon up to the implanted dopant layer, followed by selective removal of the dopant atom layer, leaving the desired high quality silicon layer on an insulator substrate.

    摘要: A method of depositing a diamondlike carbon coating on a substrate. An ionized beam of pure methane or methane and hydrogen, and having an ion kinetic energy in the range of 500-1,000 eV is impinged on a substrate to deposit, thereon, a diamondlike carbon coating. Various substrates can be utilized, and various cleaning procedures are developed for use with the particular substrates to improve the adhesion of the diamondlike carbon coatings. The methane-hydrogen ratio and the operating pressure of the ionized gas can each be varied to vary the carbon-hydrogen ratio of the resulting diamondlike coating to thereby alter the characteristics of the coating.
