A composition includes specific amounts of a virgin poly resin and a rubber-modified polystyrene that is preferably derived from post-consumer recycling. When data error is uncorrected, data and error correction codes other than uncorrected data are accumulated in the memory for data processing. A contact plug penetrates through the etch stop layer and the dielectric layer. The card dock has an outer plate formed with a large rectangular opening and four perpendicular sidewalls and an inner plate in a two-tiered structure to form a pair of parallel guide slots between the two plates of the dock. By increasing the magnitude of the resistor, the etching and deposition process will terminate prior to contact, forming an atomic-scale gap. A second voltage application part applies, to the electrodes, an ac voltage of a higher frequency than the deflection frequency.
