Ceramic capacitor

A circuit board comprising:

• a board core having a main core surface and a rear core surface;
• a ceramic capacitor having a main capacitor surface and a rear capacitor surface, having a structure in which a first inner electrode layer and a second inner electrode layer are alternately stacked with a ceramic dielectric layer interposed therebetween, and having a plurality of capacitor function units being electrically independent from each other, the ceramic capacitor being buried in the board core in a state where the main core surface and the main capacitor surface are directed in a same direction;
• and
• a buildup layer having a structure in which an interlayer insulating layer and a conductor layer are alternately stacked on the main core surface and the main capacitor surface and having a semiconductor integrated circuit device mounting region for mounting a semiconductor integrated circuit device having a plurality of processor cores on a surface of the buildup layer,
• wherein the plurality of capacitor function units are capable of being electrically connected to the plurality of processor cores, respectively, and
• wherein terminal pads formed on the semiconductor integrated circuit device mounting region are electrically connected to respective ones of the plurality of capacitor function units, respective ones of the plurality of capacitor function units being electrically connected to a corresponding one of the plurality of processor cores through a corresponding one of the terminal pads.
