The X-Ray has very short wave length and high electromagnetic radiation.
When the sample location cannot be inspected using external appearance related metrology tools, X-Ray imaging can be used to detect the internal structure of the sample due to its intensity change as a function of material density. This contrast image can show the internal structure of the sample without any physical destruction to the diagnosed region.
▍Equipment
MSS has the newest X-ray equipmet — QUADRA 7 (Nordson DAGE) and FSX-90.
