Hyperspectral X-ray imaging for nanometrology

Kristallografiâ
A tool for X-ray hyperspectral imaging has been developed. It is based on a conventional CCD driven by an algorithm that allows resolution in both energy and position. A new algorithm has been developed that allows the real-time analysis of single photon events.

Nanometrological porphyrins

Nanotechnology, 2012
A new cationic silver N-alkylpyridylporphyrin complex is able to 'sense' nanometric conductive particles with a diameter below 10 nm. The luminescence of the molecule changes its maximum from red to blue when it embraces a conductive (metallic or semiconducting) nanoparticle.

Bottom-Up Generated Height Gauges for Silicon-Based Nanometrology.

ACS Applied Materials and Interfaces, 2023
Steady progress in integrated circuit design has forced basic metrology to adopt silicon lattice parameter as a secondary realization of the SI meter that lacks convenient physical gauges for precise surface measurements at a nanoscale.

Nanometrology for evaluating rare sites for molecular homogeneity

Advanced Lithography, 2022
Here we present a methodology for identifying and characterizing nanoscale sites in EUV photoresists which deviate from the mean composition by 3σ. The methodology is based on Nano-Projectile Secondary Ion Mass Spectrometry (SIMS) operating in the in the
