Abstract

A chip package structure including a carrier, a chip, and an underfill layer is disclosed. The carrier has a number of bumps disposed thereon. The chip has an active surface. The chip is flip-chip bonded and electrically connected to the carrier through the bumps such that the active surface of the chip faces the carrier. The underfill layer is disposed on the carrier between the chip and the carrier such that a gap is maintained between the underfill layer and the chip.
