Abstract
A device includes an outer seal ring, an integrated circuit, and an inner seal ring. The outer seal ring forms a first closed loop. The integrated circuit is surrounded by the outer seal ring. The inner seal ring is between the outer seal ring and the integrated circuit. The inner seal ring forms a second closed loop that defines an enclosed region external to the integrated circuit.
Claims20
A device comprising:
- an outer seal ring forming a first closed loop;
- an integrated circuit being surrounded by the outer seal ring;
- and
- an inner seal ring between the outer seal ring and the integrated circuit, wherein the inner seal ring forms a second closed loop that defines an enclosed region external to the integrated circuit.
