Damage to encapsulated integrated circuits has recently been reported due to Laser marking of the package. A method to assess the risk of such damage is presented. The method is an analytical technique using Thermally Induced Voltage Alteration (XIVA) and Optical Beam Induced Current (OBIC) imaging.
