    Abstract: Provided is a method for preparing a compound semiconductor substrate. The method includes coating a plurality of spherical balls on a substrate, growing a compound semiconductor epitaxial layer on the substrate coated with the spherical balls while allowing voids to be formed under the spherical balls, and cooling the substrate on which the compound semiconductor epitaxial layer is grown so that the substrate and the compound semiconductor epitaxial layer are self-separated along the voids. The spherical ball treatment can reduce dislocation generations. In addition, because the substrate and the compound semiconductor epitaxial layer are separated through the self-separation, there is no need for laser lift-off process.

    Abstract: Disclosed is a method of growing a single crystal from a melt contained in a crucible. The method includes the step of making the temperature of a melt increase gradually to a maximum point and then decrease gradually along the axis parallel to the lengthwise direction of the single crystal from the interface of the single crystal and the melt to the bottom of the crucible. The increasing temperature of the melt is kept to preferably have a greater temperature gradient than the decreasing temperature thereof. Preferably, the axis is set to pass through the center of the single crystal. Preferably, the convection of the inner region of the melt is made smaller than that of the outer region thereof.

    Abstract: A method of fabricating a nano silicon on insulator (SOI) wafer having an excellent thickness evenness without performing a chemical mechanical polishing (CMP) and a wafer fabricated by the same are provided. The provided method includes preparing a bond wafer and a base wafer, and forming a dielectric on at least on surface of the bond wafer. Thereafter, an impurity ion implantation unit is formed by implanting impurity ions into the bond wafer to a predetermined depth from the surface of the bond wafer at a low voltage. The dielectric of the bond wafer and the base wafer contact each other in order to be bonded. Next, a thermal process of low temperature is performed to cleave the impurity ion implantation unit of the bond wafer. In addition, the cleaved surface of the bond wafer bonded to the base wafer is etched to form a nano scale device region. Here, the cleaved surface may be etched by performing a hydrogen surface process and a wet etching.

    Abstract: A method for slicing an ingot may improve nanotopography at a surface of a wafer. In the method, an ingot is sliced into a plurality of wafers via a slurry while slurry is supplied to a moving wire. A first wire to form a first slicing portion at the wafer firstly slices one side of the ingot. A second wire secondly slices the remaining portion of the ingot to form a second slicing portion continued from the first slicing portion, wherein the first wire has a smaller diameter than that of the second wire.

    Abstract: In a method for producing a high quality silicon single crystal by the Czochralski method, a lower portion of a solid-liquid interface of a single crystal growth is divided into a central part and a circumferential part, and the temperature gradient of the central part and the temperature gradient of the circumferential part are separately controlled. When a silicon melt located at a lower portion of a solid-liquid interface of a single crystal growth is divided into a central part melt and a circumferential part melt, the method controls the temperature gradient of the central part melt by directly controlling the temperature distribution of a melt and indirectly controls the temperature gradient of the circumferential part melt by controlling the temperature gradient of the single crystal, thereby effectively controlling the overall temperature distribution of the melt, thus producing a high quality single crystal ingot free of defects with a high growth velocity.

    Abstract: Provided are a nitride semiconductor device and method of manufacturing the same. In the method, semiconductor nanorods are vertically grown on a substrate, and then a nitride semiconductor thin film is deposited on the substrate having the semiconductor nanorods. Accordingly, a high-quality nitride semiconductor thin film can be deposited on a variety of inexpensive, large-sized substrates. Also, because the nitride semiconductor thin film containing the semiconductor nanorods can easily emit light through openings between the nanorods, internal scattering can be greatly reduced. Thus, the nitride semiconductor thin film can be usefully employed in optical devices such as light emitting diodes and electronic devices.
