In one embodiment, an electrically conductive trench in an integrated circuit allows for the formation of capacitors between the trench and other portions of the integrated circuit. For example, a capacitor may be formed between the trench and an electrically conductive line. Among other advantages, the capacitor provides a relatively large capacitance while occupying a relatively small area.

Trench-based capacitor for integrated circuits

In one embodiment, a passivation level includes a low-k dielectric. The low-k dielectric helps lower the capacitance of a metal line in a last metal level, which may be just below the passivation level. In another embodiment, the metal line is relatively thick. This helps lower the metal line's resistance and resulting RC delay.
