  • Method for sample separation and lift-out
    Publication number: 20010045511
    Abstract: When a desired portion is separated from an integrated circuit chip or a semiconductor wafer, the portion is separated so that the resulting sample can be moved to a location for examination by TEM, SEM or other means. A sample portion of the chip or wafer containing an area of interest is separated with a single cut by a focused ion-beam. Prior to separation, the sample is fixed to a micromanipulator probe. The sample is moved by the probe to the location for examination and fixed there. The probe is then detached from the sample by the focused ion-beam.
