Circuit board device and integrated circuit device

An integrated circuit device comprising:

• a circuit board comprising a mounting area, and first and second power lines and a ground pad formed on the mounting area;
• a vertical multilayer chip capacitor (MLCC) mounted on the mounting area of the circuit board, comprising:
• a capacitor body formed by laminating a plurality of dielectric layers and having first and second side faces facing each other and a lower face;
• a plurality of first and second polarity inner electrodes alternately disposed in a facing manner with the dielectric layer interposed therebetween within the capacitor body, disposed to be perpendicular to the lower face of the capacitor body, led out to the lower face of the capacitor body, and having different polarities,
• first and second outer electrodes formed on the first and second side faces, partially extending to the lower face of the capacitor body, and electrically connected to the first polarity inner electrodes;
• and
• a third outer electrode formed on the lower face of the capacitor body between the first and second outer electrodes and connected to the second polarity inner electrode;
• a first electronic component connected to the first power line;
• and
• a second electronic component connected to the second power line,
• wherein the first and second power lines are separately disposed on the mounting area, connected to the first and second outer electrodes, and electrically connected to each other only by the vertical MLCC, and
• the ground pad is disposed between the first and second power lines and connected to the third outer electrode.
