A device includes a non-insulator structure, a first ILD layer, a first thermal via, and a first electrical via. The first ILD is over the non-insulator structure. The first thermal via is through the first ILD layer and in contact with the non-insulator structure. The first electrical via is through the first ILD layer and in contact with the non-insulator structure. The first thermal via and the first electrical via have different materials and the same height. |
