  • Adaptive endpoint detection for automated delayering of semiconductor samples
    Patent number: 11171048
    Abstract: Adaptive endpoint detection is applied to delayering of a multi-layer sample utilizing a combination of dynamic and predetermined parameters. Tuned predetermined parameters, varying between layers of the sample, allow automated operation across multiple sites of a device. A semiconductor logic device is described, having a zone of thick metal layers and a zone of thin metal layers. The described techniques can be integrated with analysis operations and can be applied across a wide range of device types and manufacturing processes.
    Type: Grant
