Abstract

A method for packaging an integrated circuit chip includes the steps of: a) providing a plurality of dies and a lead frame which includes a plurality of bonding parts each having a die pad, a plurality of leads each having an end region disposed on and connected to the die pad, and a plurality of bumps each disposed on the end region of a respective one of the leads; b) transferring each of the dies to the die pad of a respective one of the bonding parts to permit each of the dies to be flipped on the respective bonding part; and c) hot pressing each of the dies and the die pad of a respective one of the bonding parts to permit each of the dies to be bonded to the bumps of the respective bonding part.
