  • Patent number: 8846429
    Abstract: A method for manufacturing a semiconductor light emitting device is provided. The method includes forming a light emitting structure by sequentially growing a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer on a semiconductor growth substrate A support unit is disposed on the second conductivity-type semiconductor layer, so as to be combined with the light emitting structure. The semiconductor growth substrate is separated from the light emitting structure. An interface between the semiconductor growth substrate and a remaining light emitting structure is wet-etched such that the light emitting structure remaining on the separated semiconductor growth substrate is separated therefrom. The semiconductor growth substrate is cleaned.

  • Patent number: 6385320
    Abstract: A surround signal processing apparatus and method can realize sound image localization and have reverberation effects. In the apparatus, left and right impulse measuring sections measure left and right impulses of a head related transfer function for an input audio signal based on a number of a plurality of lattices defined in a three dimensional space, horizontal and vertical angles defined by a center of a dummy head and the plurality of lattices. Left and right convolution operators convolve left and right channel signals of input audio signal with left and right impulses of head related transfer function, respectively, in order to localize sound image for input audio signal at an objective localization position. Left and right reverberators impart first and second reverberant sounds to left and right channel signals, respectively.
