The present invention provides a meta-data display system capable of displaying meta data related to a shot video material along with the video material synchronously to the material. The arithmetic decoder selects a mapping rule describing a mapping of a code value onto a symbol code in dependence on a context state described by a numeric current context value which is determined in dependence on previously decoded spectral values. After formation of a transistor having an LDD structure in the logic area, the silicon oxide film formed on the sides of the gate electrodes is removed by wet etching.
