SEMICONDUCTOR PACKAGES

In an embodiment, a device includes: an integrated circuit die; a first dielectric layer over the integrated circuit die; a first metallization pattern extending through the first dielectric layer to electrically connect to the integrated circuit die; a second dielectric layer over the first metallization pattern; an under bump metallurgy extending through the second dielectric layer; a third dielectric layer over the second dielectric layer and portions of the under bump metallurgy; a conductive ring sealing an interface of the third dielectric layer and the under bump metallurgy; and a conductive connector extending through the center of the conductive ring, the conductive connector electrically connected to the under bump metallurgy.
