Startup Funding: May 2023


Photonic interconnects were an area of activity in May, with two companies raising funds for what could be much faster chip-to-chip and chiplet-to-chiplet links. Microstructured optics and metasurfaces also drew investment, with four companies creating products for a range of applications from flexible LEDs to multi-wavelength spectral imaging. The large language models that power many gener... » read more

Power/Performance Bits: Feb. 23


Photonic AI accelerator There are now many processors and accelerators focused on speeding up neural network performance, but researchers at the University of Münster, University of Oxford, Swiss Federal Institute of Technology Lausanne (EPFL), IBM Research Europe, and University of Exeter say AI processing could happen even faster with the use of photonic tensor processors that can handle mu... » read more

Overlay Control for Nanoimprint Lithography


Abstract:  Nanoimprint lithography (NIL) is a promising technique for fine-patterning with a lower cost than other lithography techniques such as EUV or immersion with multi-patterning. NIL has the potential of "single" patterning for both line patterns and hole patterns with a half-pitch of less than 20nm. NIL tools for semiconductor manufacturing employ die- by-die alignment syste... » read more
