Scanning electron microscope, image of an atomic force microscopy diamond tip resting on a 7 nm delayered SRAM.   AFM-in-SEM can simultaneously mill and look for electrical anomalies. Itโ€™ll be a great talk.

Did you know that the Heathrow control tower has a set of German Zeiss spotting binoculars from the Second World War?
