  • Patent number: 6939209
    Abstract: A reliable, inexpensive “back side” thinning process and apparatus therefor, capable of globally thinning an integrated circuit die to a target thickness of 10 microns, and maintaining a yield of at least 80%, for chip repair and/or failure analysis of the packaged die. The flip-chip packaged die is exposed at its backside and mounted on a lapping machine with the backside exposed. The thickness of the die is measured at at least five locations on the die. The lapping machine grinds the exposed surface of the die to a thickness somewhat greater than the target thickness. The exposed surface of the die is polished. The thickness of the die is again measured optically with high accuracy. Based on the thickness data collected, appropriate machine operating parameters for further grinding and polishing of the exposed surface are determined. Further grinding and polishing are performed. These steps are repeated until the target thickness is reached.

  • Publication number: 20040014401
    Abstract: A reliable, inexpensive “back side” thinning process, capable of globally as well as locally thinning an integrated circuit die to a target thickness of 10 microns, and maintaining a yield of at least 80%, for chip repair and/or failure analysis of the packaged die. The flip-chip or wire-bond packaged die is mounted on a thinning/polishing tool with the backside accessible. The thinning/polishing tool can be a lapping machine used for global thinning, or a mini milling machine, laser, FIB, or E-beam machine for local thinning. The thickness of the die is measured at at least five locations on the die before thinning. The thinning tool removes silicon on the exposed surface of the die to a thickness somewhat greater than the target thickness. The exposed surface of the die is polished. The thickness of the die is again measured optically with high accuracy.
