  • Method of fabricating GaN
    Patent number: 7462893
    Abstract: A method of fabricating a thick gallium nitride (GaN) layer includes forming a porous GaN layer having a thickness of 10-1000 nm by etching a GaN substrate in a reaction chamber in an HCI and NH3 gas atmosphere and forming an in-situ GaN growth layer in the reaction chamber. The method of forming the porous GaN layer and the thick GaN layer in-situ proceeds in a single chamber. The method is very simplified compared to the prior art. In this way, the entire process is performed in one chamber, and in particular, GaN etching and growth are performed using an HVPE process gas such that costs are greatly reduced.

  • Data modulating method and apparatus, data demodulating method and apparatus, and code arranging method
    Patent number: 7450034
    Abstract: In a data demodulating method and apparatus, and a code arranging method, a multiplexer multiplexes an input data stream divided by a predetermined length into a plurality of types of pseudo random data streams using multiplexed information of predetermined bits by applying a predetermined multiplexing method to each of the pseudo random data streams. An encoder RLL-modulates the plurality of types of pseudo random data streams to create a modulated code stream including a minimum of DC components. The multiplexer generates the random data streams by inconsecutively scrambling the input data stream using the multiplexed information. The encoder weak DC-free RLL-modulates each of the multiplexed data streams without using a DC control sub code conversion table to which additional bits are added and provides a code stream including a minimum of DC components among multiplexed, RLL-modulated code streams.
