Laser-driven secondary sources for next-gen Metrology
下午 2:00 - 下午 2:25
Miniaturization of semiconductor device structures and the adoption of advanced 3D packaging are outpacing conventional metrology, demanding new, robust approaches for high-volume manufacturing. As future device geometries and material stacks evolve, metrology will require higher resolution in x, y, and z-dimensions —and richer material contrast—than today’s radiation sources can deliver. TRUMPF is developing laser-driven “secondary sources” that deliver the next order of brightness and/or flux in the soft x-ray (SXR) and x-ray regimes. We present recent breakthroughs and outline ongoing development activities.
Key Technologies Covered
