A method for direct electrical detection of proteins, peptides and the like, and their interactions includes an electrode arrangement, a current/voltage provider, and a circuit analyzer. The electrode arrangement has an interdigitated electrode pair including a first electrode and a second electrode. Coupled to the electrode arrangement is a signal generator adapted to provide a signal (e.g., an alternating current or voltage) having a selected range of frequencies. The analyzer is coupled to the electrode arrangement and is operative to analyze an electrical parameter of the circuit as the signal is applied. An analytic method includes measuring changes in one or more parameters of the circuit over the range of frequencies. By such measurement, the device can determine whether a target moiety has been bound by a probe attached to the electrode(s). The device can also specifically identify the intermolecular system detected, i.e., by 'fingerprinting' the electrical response of each molecule or intermolecular complex.

A method of etching a metallic film on a substrate. This method operates to inject an oxidizing agent through the use of a carrier gas to etch a source metal in the presence of a reducing agent such that the rate of etching can be controlled by controlling the flow rate of the carrier gas, the substrate temperature, the pulse widths of the oxidizing and reducing agents, and the number of etching phases.

An atomic layer deposition method to deposit an oxide nanolaminate thin film is provided. The method employs a nitrate ligand in a first precursor as an oxidizer for a second precursor to form the oxide nanolaminates. Using a hafnium nitrate precursor and an aluminum precursor, the method is well suited for the deposition of a high k hafnium oxide/aluminum oxide nanolaminate dielectric for gate dielectric or capacitor dielectric applications on a hydrogen-terminated silicon surface.

A method of forming a layer of high-&kgr; dielectric material in an integrated circuit includes preparing a silicon substrate; depositing a first layer of metal oxide using ALD with a metal nitrate precursor; depositing another layer of metal oxide using ALD with a metal chloride precursor; and completing the integrated circuit.

Methods of forming hafnium oxide, zirconium oxide and nanolaminates of hafnium oxide and zirconium oxide are provided. These methods utilize atomic layer deposition techniques incorporating nitrate-based precursors, such as hafnium nitrate and zirconium nitrate. The use of these nitrate based precursors is well suited to forming high dielectric constant materials on hydrogen passivated silicon surfaces.

A bright, short wavelength blue-violet phosphor for electroluminescent displays comprises an alkaline-based halide as a host material and a rare earth as a dopant. The host alkaline chloride can be chosen from the group II alkaline elements, particularly strontium chloride (SrCl.sub.2) or calcium chloride (CaCl.sub.2), which, with a europium (Eu) or cerium (Ce) rare earth dopant, electroluminesces at a peak wavelength of 404 and 367 nanometers (nm) respectively. The resulting emissions have CIE chromaticity coordinates which lie at the boundary of the visible range for the human eye thereby allowing a greater range of colors for full color flat panel electroluminescent (FPEL) displays.
