摘要:
IR microscopy investigations of tape automated bonding (TAB) contacted chips are described. The ability of the method to detect mechanical stress fields in silicon as induced by a bump or a load is demonstrated. In the case of plastic coated TAB devices the degradation of the chip after thermal cycling is observed a long time before it may be registered electrically.
