Method of fabricating anti-warp package

摘要

An anti-warp package comprising a packaging substrate, a chip and a stiffening member is provided. The chip is disposed on a top surface of the packaging substrate. The stiffening member is disposed on a bottom surface of the packaging substrate in a location underneath the surrounding area of the chip. Through the disposition of a stiffening member, warping stress on the packaging substrate when the chip is encapsulated by molding compound is counterbalanced.
