A chip includes a first group of dummy bumps disposed at a top surface of the chip in a first corner of the chip, a second group of dummy bumps disposed at the top surface of the chip in a second corner of the chip, and active bump connectors disposed at the top surface of the chip. The chip also includes an outer seal ring disposed around a periphery of the chip, a first seal ring arrangement disposed around the first group of dummy bumps, and a second seal ring arrangement disposed around the second group of dummy bumps. The first seal ring arrangement and second seal ring arrangement are disposed in dielectric layers underlying the first and second groups of dummy bumps.
