  • Publication number: 20200118916
    Abstract: A semiconductor device includes a first substrate, a pad array, a conductive bump, a first via and a dielectric. The pad array, formed on a surface of the first substrate, includes a first type pad and a second type pad at a same level. The conductive bump connects one of the first type pad of the second type pad to a second substrate. The first via, connected to a conductive feature at a different level to the first type pad, is located within a projection area of the first type pad and directly contacts the first type pad. The second type pad is laterally connected with a conductive trace on the same level. The conductive trace is connected to a second via at a same level with the first via. The dielectric in the first substrate contacts the second type pad. The second type pad is floated on the dielectric.
