    摘要: A goniometer for performing scanning probe microscopy on a substrate surface is disclosed. The goniometer has a cantilever, having a cantilevered end and a supported end and a tip disposed at the cantilevered end of the cantilever. The goniometer also has a block disposed at the supported end of the cantilever. The block has at least one pair of piezoelectric layers, a pair of electrodes disposed about each individual piezoelectric layer such that varying a potential difference applied between the individual electrodes of a pair of electrodes causes the corresponding piezoelectric layer to deform, and a first insulating material disposed between the individual electrodes for insulating the individual electrodes from each other. The individual piezoelectric layers are deformed at different rates resulting in a deformity of the block and tilting of the cantilever and tip connected therewith. Also disclosed are methods of using the goniometer of the present invention to measure the interactive forces between two molecular structures using a scanning probe microscope equipped with a goniometer of the present invention.

    摘要: A method of producing a thin film comprising a conductive metal silicide and the products produced therefrom are disclosed. The method is much less complex than methods employed in the prior art for producing conductive thin films and the method reduces substrate damage by maintaining processing temperatures at about 1,000.degree. C. or less. The process employs a stable suspension comprising ultrafine powders in a solvent. This suspension is deposited on a surface of a substrate and is subsequently heated to form a thin conductive film. The thin conductive film comprises polycrystalline metal silicide, preferably a refractory metal silicide, and may also contain silicon. Composites comprising the thin conductive films and a substrate are also disclosed. The process and products are particularly suited for use in VLSI and VVLSI production.

    摘要: A structure includes a metal nitride film of the form MN, where M is selected from the group consisting of Ga, In, AlGa, AlIn, and AlGaIn. The structure has at least one electrically conductive metal region that is formed within and from the metal nitride film by a thermal process driven by absorption of light having a predetermined wavelength. Single films comprised of AlN are also within the scope of this invention, wherein an Al trace or interconnect is formed by laser radiation of wavelength 248 nm so as to contact circuitry that exists under the film. Multilayered stacks of films are also within the scope of the teachings of this invention. In this case each film layer may be separately deposited and then illuminated to selectively form the desired electrical connection(s), which may also connect to conductive feature(s) in an underlying layer, or a plurality of metal nitride layers are stacked bottom to top in order of increasing electronic band gap energy value, and then the conductive features are written into selective ones of the layers by controlling the wavelength of the light to be absorbed in a desired layer. The teachings of this invention can be employed to fabricate fuses and anti-fuses enabling selective circuit customization, test and repair. Also disclosed is a technique for forming electrical resistors in a metal nitride layer by adjusting the electrical resistance of the metallization formed from the metal nitride film layer.
