Title:
CAPACITOR ELEMENT, MODULE AND SEMICONDUCTOR COMPOSITE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/054059
Kind Code:
A1
Abstract:
A capacitor element 1 is provided with: a capacitor unit 10 which comprises a positive electrode plate 11 that has a porous part 11B on at least one main surface of a core part 11A, a dielectric layer 13 that is arranged on the surface of the porous part 11B, and a negative electrode layer 12 that is arranged on the surface of the dielectric layer 13; and a through conductor 20 which penetrates through the dielectric layer 13 and the positive electrode plate 11 in the thickness direction. The through conductor 20 comprises: a negative electrode through conductor 20A which is electrically connected to the negative electrode layer 12; and a positive electrode through conductor 20B which is electrically connected to the positive electrode plate 11. The negative electrode through conductor 20A comprises a first negative electrode through conductor 20A1 and a second negative electrode through conductor 20A2. The positive electrode through conductor 20B comprises a first positive electrode through conductor 20B1. When viewed in plan from the thickness direction of the positive electrode plate 11, the center to center distance between the first positive electrode through conductor 20B1 and the first negative electrode through conductor 20A1 is equal to the center to center distance between the first positive electrode through conductor 20B1 and the second negative electrode through conductor 20A2.
