Synopsys' Ian Land, Kenneth Larsen, and Rob Aitken find that a new approach will be required to ensure that higher volume 3D heterogeneous integration (3DHI) designs can function reliably and successfully in aerospace, defense, and government systems. Siemens' John Golding provides a primer on the fundamental concepts related to signal integrity, including key topics such as transmission lin... » read more

Laser printer for photonic circuits Researchers from the University of Washington and University of Maryland propose a faster, cheaper way to fabricate and reconfigure photonic integrated circuits. The method uses a laser writer to write, erase, and modify circuits into a thin film of phase-change material similar to what is used for recordable CDs and DVDs. The researcher say the method co... » read more

Etching tellurite glass Physicists from EPFL and Tokyo Tech propose a way to create photoconductive circuits, where the circuit is directly patterned onto a tellurite glass surface with femtosecond laser light. The exposure formed nanoscale tellurium and tellurium oxide crystals, both semiconducting materials. “Tellurium being semiconducting, based on this finding we wondered if it would ... » read more

Siemens' John McMillan finds that while 3D-IC capabilities are ready for mainstream, mass adoption success depends on how easily, effectively, and efficiently a solution can be delivered and points to five workflow adoption focus areas. Cadence's Andre Baguenie shows how to easily convert a logic signal to an electrical value using Verilog-AMS and the transition filter. Synopsys' Chris Cl... » read more

Memristor-based Bayesian neural network Researchers from CEA-Leti, CEA-List, and CNRS built a complete memristor-based Bayesian neural network implementation for classifying types of arrhythmia recordings with precise aleatoric and epistemic uncertainty. While Bayesian neural networks are useful for at sensory processing applications based on a small amount of noisy input data because they ... » read more

3D stacking of 2D materials Researchers from Penn State University demonstrated monolithic 3D integration with 2D transistors made from 2D semiconductors called transition metal dichalcogenides. The 2D materials have unique electronic and optical properties, including sensitivity to light, making them ideal for use as sensors. “One challenge is the process temperature ceiling of 450 degre... » read more

Startup Funding: December 2023
By Jesse Allen - 10 Jan, 2024 - Comments: 0

Photonics and optics were strong in December, with investors funding two different companies using photonic technologies to develop AI chips and interconnects. Another key area — metaoptics — combines what traditionally would be separate lenses and optical components into a single, flat nanopatterned device. Metaoptics are being deployed in applications ranging from AI processing and sensor... » read more

High mobility graphene Researchers at the Georgia Institute of Technology and Tianjin University created a functional semiconductor made from graphene that is compatible with conventional microelectronics processing methods. "We now have an extremely robust graphene semiconductor with 10 times the mobility of silicon, and which also has unique properties not available in silicon," said Walt... » read more
