FemtoFarad/TeraOhm Endpoint Detection for Microsurgery of Integrated Circuit Devices

Interactive electrical endpoint detection when thinning conductive and capacitive materials opens the door to approaching a suspect site in an IC without relying on the traditional iterative approach. Controlled approach of embedded conductors in insulators (packages) as well as controlled die thinning with submicron control will be shown, allowing safe approach to the desired feature without overshoot.
