Once a failed device has been found and isolated from the rest of the die, the true detective work begins to identify the root cause of that failure. The cause of that failure could be due to inconsistency in the chemistry of the process, foreign contaminant particles or variation in crystalline structure of deposited material amongst many other possibilities.
Many of these potential fault causes are extremely small, typically on the order of a few nanometres. Our latest generation Ultim Extreme energy dispersive x-ray spectrometer (EDS) allows you to work at the same conditions that you would image in the SEM to get elemental information at 10 nm resolution on bulk devices.
In the TEM our Ultim Max TEM detectors are powered by AZtecTEM to ensure the higher possible accuracy quantitative analysis at the highest possible resolution.
