An object of the present invention is to provide a semiconductor device having high operation characteristic and reliability. The process comprises hydrogenating a first olefin stream that has alkynes andor dienes in the presence of excess hydrogen and a first hydrogenation catalyst. can be selected for optimum results in a desired application. A plurality of dust is laid on the vibration sieve. If the caller is determined to be using a mobile communication device, a confirmation of the selection is sent to the mobile communication device. At least one word line partially overlapping with the top-thin oxide layer.
