31. Potential applications and requirements of photoelectron sources for Metrology

Dr Gil Delgado

10/5/23, 8:30 AM

Advanced semiconductor manufacturing requires high-end metrology to have successful semiconductor process control.
Currently, high-end metrology requires lab tools to assist in semiconductor metrology. However, this is slow, expensive, and, often destructive. Fabs need inline metrology systems.
New memory and logic semiconductor designs and architectures are transitioning to 3-D structures....

32. Plasmonic vortices as sources of angular momentum electron beams

Dr Hrvoje Petek

10/5/23, 8:55 AM

The excitation laser polarization and coupling geometry metastructures define the spin-orbit interaction of surface plasmon polaritons at metal-vacuum interfaces. We image the topological plasmonic fields by imaging nonlinear electron emission by photoemission electron microscopy. We record with nanometer spatial and femtosecond temporal resolution the generated space-time spin textures of...
