Semiconductor technology advancements and added device complexity put ever more stringent requirements on semiconductor manufacturing process monitor and control. Pressure exerted on devices during grinding, CMP, polishing, lamination, bonding, pick and place encapsulation, electrical testing, and packaging can cause failures that may not even be measurable using conventional sensors.
Currently chip test, monitoring and packaging process control is widely done via optical displacement sensors and electrical testing which do not adequately measure the pressure on devices. Without the ability to adequately monitor these processes, root cause failure identification is challenging and maintaining or improving process quality and yield are difficult.
In this webinar the piezoelectric sensor technology has been described and how it used to improve chip test, monitoring and packaging semiconductor processes.
