The present invention discloses a method for providing e-commerce service to a physical community. The apparatus includes an optical element with a pupil raster element, and a projection objective with a real entrance pupil. 01 at % to 10 at % and the doping concentration of the manganese ranges from 0. If the temperature of the computer is in the predetermined temperature range and the voltage of the computer is normal, the controller wakes up the computer at the power-off state. A disclosed capacitor includes a semiconductor substrate, a lower electrode on the semiconductor substrate, a nitride layer on the lower electrode, the nitride layer having an uneven surface formed by isotropic etching and nitridation of silicon nitride, and an upper electrode on the nitride layer. A frame is fixed and supported at the rear of a front panel forming the front portion of the display apparatus, and a separate bracket member is not mounted on the edges of the front panel.
