Abstract

A semiconductor device includes a carrier, a die including a first surface and a second surface, a plurality of first conductive bumps disposed between the second surface of the carrier and the die, wherein the die is flip bonded on the carrier, and a molding disposed over the carrier and surrounding the die, wherein the molding includes a recessed portion disposed on the first surface of the die thereby leaving a portion of the first surface is uncovered by the molding. Further, a method of manufacturing a semiconductor device includes providing a carrier, flip bonding a die on the carrier, disposing a rubber material on a first surface of the die and within the first surface of the die, and forming a molding surrounding the rubber material and covering the carrier.
