A magnetic resonance imaging apparatus includes a static magnetic field generating unit, a main coil, a radio frequency coil, and a shimming structure unit. A computer implemented method may include executing a routine that receives as input first packet information. A mask layer is then formed over the noble metal layer and patterned to leave a portion of the noble metal layer exposed. A capacitor trench extends in the semiconductor well region and an upper capacitor electrode extends in the capacitor trench. The task description may also include textual, voice or other message which can be displayed andor played back to a user.
