Title:
キャパシタ、多層配線基板及び半導体装置
Document Type and Number:
Japanese Patent JP4365166
Kind Code:
B2
Abstract:
A capacitor structure includes a first electrode provided on an insulating basic member, a dielectric member provided on the electrode, a second electrode provided on the dielectric member, and a plurality of electrode terminals aligned in a grid on the electrode. Respective electrode terminals are aligned such that opposite polarities (+,-) are alternately allocated to neighboring electrode terminals, and respective divided partial electrodes of the first and second electrodes are also aligned such that opposite polarities (+,-) are alternately allocated to neighboring electrode terminals. According to this structure, the inductance of the capacitor structure is reduced and thus the decoupling effect can be effectively achieved. This contributes to a stable operation in the high-frequency (GHz band) range.
