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

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

By Ann Mutschler - 15 Jan, 2024 - Comments: 0

Experts at the Table: Semiconductor Engineering sat down to talk about the need for the right type of data, why this has to be done early in the design flow, and how 3D-IC will affect all of this, with Bill Mullen, distinguished engineer at Ansys; Rajat Chaudhry, product management group director at Cadence; Heidi Barnes, senior applications engineer at Keysight; Venkatesh Santhanagopalan, prod... » read more

Chip Industry Silos Are Crimping Advances
By Brian Bailey - 11 Jan, 2024 - Comments: 0

Change is never easy, but it is more difficult when it involves organizational restructuring. The pace of such restructuring has been increasing over the past decade, and often it is more difficult to incorporate than technological advancements. This is due to the siloed nature of the semiconductor industry, both within the industry itself, and its relationship to surrounding industries. Inc... » read more

ChatGPT’s ability to understand and respond to complex instructions and deliver detailed responses to user prompts has led to an explosive rise in its popularity with the public. If you were to search online for “ChatGPT tips,” you can find content to help you use the tool to tailor resumes to job postings, create... » read more

Glitch Power Issues Grow At Advanced Nodes
By Ann Mutschler - 11 Jan, 2024 - Comments: 0

An estimated 20% to 40% of total power is being wasted due to glitch in some of the most advanced and complex chip designs, and at this point there is no single best approach for how and when to address it, and mixed information about how effective those solutions can be. Glitch power is not a new phenomenon. DSP architects and design engineers are well-versed in the power wasted by long, sl... » read more
