Silicon’s Long Game
By Ed Sperling - 18 Dec, 2017 - Comments: 0

The era of all-silicon substrates and copper wires may be coming to an end. Progress in the future increasingly depends on more exotic combinations of materials that are developed for specific applications. But after years of predicting the death of silicon, it appears those predictions may be premature. That's not always obvious, given the growing number of chemical combinations being creat... » read more

Fan-Outs vs. TSVs
By Jeff Dorsch - 13 Dec, 2017 - Comments: 0

Two years ago, at the annual IMAPS conference on 2.5D and 3D chip packaging, the presentations were dominated by talk of fan-out wafer-level packaging. There was almost no talk of through-silicon vias, which previously had been heralded as vital to 2.5D and 3DIC packaging. Fast forward to this month's 3D Architectures for Heterogeneous Integration and Packaging conference in Burlingame, Cali... » read more

Power/Performance Bits: Oct. 3
By Jesse Allen - 03 Oct, 2017 - Comments: 0

Slowing down photonics Researchers at the University of Sydney developed a chip capable of optical data into sound waves, slowing data transfer enough to process the information. While speed is a major bonus with photonic systems, it's not as advantageous when processing data. By turning optical signals into acoustic, data can be briefly stored and managed inside the chip for processing, re... » read more

Silicon Photonics: Solving Process Variation And Manufacturing Challenges
By Sandy Wen - 17 Aug, 2017 - Comments: 0

As silicon photonics manufacturing gains momentum with additional foundry and 300mm offerings, process variation issues are coming to light. Variability in silicon processing affects the waveguide shape and can result in deviation in effective indices, propagation loss, and coupling efficiency from the intended design. In this article, we will highlight process variation issues that can occur i... » read more

The Great Machine Learning Race
By Ed Sperling - 03 Apr, 2017 - Comments: 2

Processor makers, tools vendors, and packaging houses are racing to position themselves for a role in machine learning, despite the fact that no one is quite sure which architecture is best for this technology or what ultimately will be successful. Rather than dampen investments, the uncertainty is fueling a frenzy. Money is pouring in from all sides. According to a new Moor Insights report,... » read more

Analog’s Rising Status
By Ann Mutschler - 08 Dec, 2016 - Comments: 1

As more sensors and actuators are added into electronic devices, pressure is growing to more seamlessly move data seamlessly back and forth between analog and digital circuitry. [getkc id="37" kc_name="Analog"] and digital always have fit rather uncomfortably together, and that discomfort has grown as [getkc id="81" kc_name="SoCs"] are built using smaller feature sizes. While digital transis... » read more

Power/Performance Bits: Nov. 15
By Jesse Allen - 15 Nov, 2016 - Comments: 0

Another record-breaking tandem perovskite solar cell University of California, Berkeley, and Lawrence Berkeley National Laboratory scientists report a new design for perovskite solar cells that achieves an average steady-state efficiency of 18.4%, with a high of 21.7% and a peak efficiency of 26%. "This has a great potential to be the cheapest photovoltaic on the market, plugging into any... » read more
