A multilayer capacitor array includes a capacitor body, two first signal terminal electrodes, two second signal terminal electrodes, two grounding terminal electrodes, one first outer connecting conductor, and one second outer connecting conductor, where the capacitor body includes first and second signal inner electrodes, and first to third grounding inner electrodes. The business system interface includes an embedded business system user interface contained within a user interface of the IWP application. An insulating layer is formed over the gate dielectric layer.
