Abstract
In one embodiment, a passivation level includes a low-k dielectric. To prevent the low-k dielectric from absorbing moisture when exposed to air, exposed portions of the low-k dielectric are covered with spacers. As can be appreciated, this facilitates integration of low-k dielectrics in passivation levels. Low-k dielectrics in passivation levels help lower capacitance on metal lines, thereby reducing RC delay and increasing signal propagation speeds.
