Patent number: 6103600Abstract: A quantum dot and quantum fine wire forming method is provided which can allow control of the position for crystalline particle growth and enables formation of particles with high uniformity in size and density and with high reproducibility. After an Si substrate is formed with a step by a dry etching method, an SiO.sub.2 film is formed on the surface of the substrate. The interior of a reaction chamber is evacuated to a vacuum of 10.sup.-8 Torr, and then an Si.sub.2 H.sub.6 gas is introduced into the reaction chamber to flow therein so that Si crystal particles (quantum dots) are formed along the step. The step is formed by conventional photolithography and dry etching; therefore, the position for quantum dot growth can be easily controlled. By controlling the rate and time period of gas flow and the temperature of the substrate it is possible to form quantum fine wires, and to control the size of quantum dots and/or thickness of quantum fine wires.Type: GrantFiled: September 24, 1998Date of Patent: August 15, 2000Assignee: Sharp Kabushiki KaishaInventors: Tohru Ueda, Yasumori Fukushima, Kenta Nakamura
