    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.
