20200090826 · 2020-03-19 ·

An apparatus is disclosed for the examination and inspection of integrated devices such as integrated circuits. X-rays are transmitted through the integrated device, and are incident on a photoemissive structure that absorbs x-rays and emits electrons. The electrons emitted by the photoemissive structure are shaped by an electron optical system to form a magnified image of the emitted electrons on a detector. This magnified image is then recorded and processed. For some embodiments of the invention, the photoemissive structure is deposited directly onto the integrated device. In some embodiments, the incidence angle of the x-rays is varied to allow internal three-dimensional structures of the integrated device to be determined. In some embodiments, the recorded image is compared with a reference data to enable inspection for manufacturing quality control.

Quantum-limited extreme ultraviolet coherent diffraction imaging

Apparatus and methods for coherent diffraction imaging. This is accomplished by acquiring data in a CDI setup with a CMOS or similar detector. The object is illuminated with coherent light such as EUV light which may be pulsed. This generates diffraction patterns which are collected by the detector, either in frames or continuously (by recording the scan position during collection). Pixels in the CDI data are thresholded and set to zero photons if the pixel is below the threshold level. Pixels above the threshold may be set to a value indicating one photon, or multiple thresholds may be used to set pixels values to one photon, two photons, etc. In addition, multiple threshold values may be used to detect different photon energies for illumination at multiple wavelengths.
