Two-Day Course
Dates to be announced; 8:30am – 5:00pm
Dr. Anis Rahman, Applied Research & Photonics, Inc., Harrisburg, PA
COURSE DESCRIPTION
This advanced professional course provides an in-depth exploration of Dendrimer Dipole Excitation (DDE) based T-ray metrology—a disruptive technology redefining the limits of non-destructive testing and high-resolution imaging. Designed for engineers, researchers, and technical leaders, the curriculum bridges the gap between fundamental terahertz (THz) physics and practical industrial applications across the semiconductor, nanotechnology, and biotech sectors. Participants will master the principles of DDE, a patented mechanism that leverages electro-optic dendrimers to generate high-power, stable, and continuous-wave T-rays. Unlike traditional methods, DDE-based systems can “break” the Abbe diffraction limit, achieving sub-nanometer 3D resolution essential for the next generation of atomic-scale manufacturing and molecular research.
Key Learning Objectives
- The DDE Advantage: Understand the physics of Dendrimer Dipole Excitation and how it outperforms legacy Auston switch and inorganic crystal-based THz sources.
- Advanced Metrology Techniques: Learn to utilize T-ray time-domain spectroscopy (TDS) and 3D nanoscanning for volume imaging and layer-by-layer analysis.
- Industrial Integration: Explore “Lab-to-Fab” strategies for implementing in-line, non-contact quality control in semiconductor fabrication.
- Cross-Disciplinary Applications:
o Semiconductors: Detecting lattice defects (e.g., in SiC), measuring carrier concentration, and inspecting buried 3D interfaces.
o Biotechnology: Label-free probing of DNA binding, protein conformational changes, and pharmaceutical tablet porosity.
o Nanotechnology: Characterizing thin-film stacks and nanomaterial properties with picometer-scale precision.
