Patent number: 9337425Abstract: Methods of manufacturing a resistance change layer and a resistive random access memory device are provided. The method of manufacturing a resistance change layer includes forming a preliminary resistance change layer including an oxide semiconductor material on a substrate and irradiating the preliminary resistance change layer with an electron beam to a predetermined depth. On a path along which the electron beam is irradiated, a composition ratio of the resistance change layer changes in a direction in which a density of oxygen vacancies of the oxide semiconductor material increases. Accordingly, the composition ratio of a resistance change layer is easily controlled using electron beam irradiation. In addition, since interfacial surface roughness and internal defect structures of an oxide semiconductor are controlled by electron beam irradiation, a resistance change ratio is improved and thereby device characteristics can be improved.Type: GrantFiled: March 31, 2014Date of Patent: May 10, 2016Assignee: INDUSTRY-UNIVERSITY COOPERATION FOUNDATION HANYANG UNIVERSITYInventors: Eun Kyu Kim, Dong Uk Lee, Seong Guk Cho, Gyu Jin Oh, Byung Cheol Lee, Dongwook Kim, Sang Woo Pak, Hyung Dal Park

Patent number: 6696313Abstract: A method for aligning quantum dots effectively controls a growth position of the quantum dots for obviating an irregularity of a position of spontaneous formation quantum dots, and thus aligns the quantum dots in one-dimension (1-D) or two-dimension (2-D). A semiconductor device fabricated using the method manufactures a superlattice layer layer for adjusting an internal strain distribution by alternately depositing two semiconductor materials having different lattice constant, and grows spontaneous formation quantum dots on the superlattice layer. As a result, a strained force caused by the superlattice layer influences on the quantum dots so that the quantum dots can be regularly aligned.Type: GrantFiled: September 7, 2001Date of Patent: February 24, 2004Assignee: Korea Institute of Science and TechnologyInventors: Yong Ju Park, Eun Kyu Kim, Kwang Moo Kim

Patent number: 6683013Abstract: Disclosed is a method of forming a quantum dots array. In the method of the present invention, a structure of wire-like quantum dots with good quality is formed in materials having an inconsistency in the lattice constant on a tilted substrate by using the binding property of atomic bonding due to chemical bonding steps of the tilted substrate, and the spacing of the wire-like quantum dots is varied by using the step width of the tilted substrate which is transformed due to a partial pressure of a source gas and the thickness of a buffer layer. The invention allows materials having an inconsistency in the lattice constant to be freely formed in the form of quantum wires with a growing technique only and accordingly to be used as base materials in use for manufacture of novel concept of optoelectronic devices which have not been obtained so far.Type: GrantFiled: March 19, 2002Date of Patent: January 27, 2004Assignee: Korea Institute of Science and TechnologyInventors: Eun Kyu Kim, Yong Ju Park, Hyo Jin Kim, Tae Whan Kim

Patent number: 6475886Abstract: Disclosed is a method for forming a nano-crystal. In the above method, there is prepared a substrate having a metal film or a semiconductor film formed thereon. A focused-ion beam is irradiated onto a plurality of positions on a surface of the metal film or the semiconductor film, whereby the metal film or the semiconductor film is removed at a focal portion of the focused-ion beam but an atomic bond in the metal film or the semiconductor film is broken at an overlapping region of the focused-ion beams due to an radiation effect of the focused-ion beam to form the nano-crystal. The method allows a few nm or less-sized nano-crystals to be formed with ease and simplicity using the focused-ion beam. As a result, the formed nano-crystals come to have a binding energy capable of restraining thermal fluctuation phenomenon at room temperature and thereby it becomes possible to fabricate a tunneling transistor capable of being operated at room temperature.Type: GrantFiled: December 26, 2001Date of Patent: November 5, 2002Assignee: Korea Institute of Science and TechnologyInventors: Eun Kyu Kim, Young Ju Park, Tae Whan Kim, Seung Oun Kang, Dong Chul Choo, Jae Hwan Shim
