Abstract: The amount of signal propagation and moisture penetration and corresponding reliability problems due to moisture penetration degradation in an IC can be reduced by fabricating a wide seal ring with a channel having offset ingress and egress portions.

Abstract translation: 通过制造具有偏移入口和出口部分的通道的宽密封环，可以减少信号传播和水分渗透的量以及由于IC中的水分渗透降解引起的相应的可靠性问题。

Abstract: A tunable guard ring for improved circuit isolation is disclosed. In an exemplary embodiment, an apparatus includes a closed loop guard ring formed on an integrated circuit and magnetically coupled by a selected coupling factor to a first inductor formed on the integrated circuit. The apparatus also includes a tunable capacitor forming a portion of the closed loop guard ring and configured to reduce magnetic field coupling from the first inductor to a second inductor.
