Abstract: A method of channel coding a digital communication system and a device using the same is provided. The method includes quantizing analog data to digital data, the digital data corresponding to a predetermined number of digital codes; allocating channel codes to the digital codes, as a Hamming distance between a pair of channel codes corresponding to any pair of the digital codes is proportional to a difference between analog values of the pair of the digital codes; and channel coding the digital data by using the channel codes which are allocated to the digital codes to generate channel coded digital data. Accordingly, digital data, such as multimedia digital data without source coding and the like, of which information significance is different may be effectively transmitted and received.

Abstract: A method of manufacturing a semiconductor device including a contact plug includes forming an insulation interlayer pattern and a protection pattern for protecting the insulation interlayer pattern using a mask pattern. The insulation interlayer includes a contact hole through which a surface of the substrate is partially exposed. A spacer is formed on a sidewall of the contact hole, and a first conductive layer is formed to a sufficient thickness to fill up the contact hole. The first conductive layer makes contact with the substrate at the exposed surface thereof. A contact plug is formed in the contact hole by removing the first conductive layer until a top surface of the insulation interlayer pattern is exposed. Accordingly, a contact failure between the contact plug and a conductive pattern adjacent to the contact plug is prevented.

Abstract: After an insulation layer is formed on a substrate, a contact hole is formed through the insulation layer. A recessed plug is formed to partially fill up the contact hole. The recessed plug has a height substantially smaller than a depth of the contact hole. A metal wiring structure is formed on the recessed plug and on the insulation layer. A lower portion of the metal wiring structure, formed within the contact hole, prevents damage to the recessed plug during an etching process for forming the metal wiring structure. Therefore, the recessed plug may be formed without damage thereof even if an alignment error occurs between an etching mask and the recessed plug during metal wiring structure formation.
