    摘要: The present invention relates to a method for depositing a dielectric material comprising a transition metal oxide. In an initial step, a substrate is provided. In a further step, a first precursor comprising a transition metal containing compound, and a second precursor predominantly comprising at least one of water vapor, ozone, oxygen, or oxygen plasma are sequentially applied for depositing above the substrate a layer of a transition metal containing material. In another step, a third precursor comprising a dopant containing compound, and a fourth precursor predominantly comprising at least one of water vapor, ozone, oxygen, or oxygen plasma are sequentially applied for depositing above the substrate a layer of a dopant containing material. The transition metal comprises at least one of zirconium and hafnium. The dopant comprises at least one of barium, strontium, calcium, niobium, bismuth, magnesium, and cerium.

    摘要: In various embodiments, a method for producing a solar cell is provided. In accordance with the method, through-holes may be formed in a solar cell substrate having the basic doping of a first conduction type. Furthermore, predetermined surface regions of a first surface of the solar cell substrate which include at least one portion of the through-holes may be highly doped with a second, opposite conduction type; and simultaneously or subsequently other surface regions of the first surface are lightly doped with the second conduction type. Furthermore, first and second metallic contacts may subsequently be formed in such a way that the second metallic contacts are electrically isolated from the first metallic contacts.

    摘要: This invention concerns nanoscale products, such as electronic devices fabricated to nanometer accuracy. It also concerns atomic scale products. These products may have an array of electrically active dopant atoms in a silicon surface, or an encapsulated layer of electrically active donor atoms. In a further aspect the invention concerns a method of fabricating such products. The methods include forming a preselected array of donor atoms incorporated into silicon. Encapsulation by growing silicon over a doped surface, after desorbing the passivating hydrogen. Also, using an STM to view donor atoms on the silicon surface during fabrication of a nanoscale device, and measuring the electrical activity of the donor atoms during fabrication of a nanoscale device. Such products and processes are useful in the fabrication of a quantum computer, but could have many other uses.
