Walking across a carpet can generate up to 35,000 volts of static charge, which is tens of thousands of times higher than the operating voltages of most integrated circuits. When charge build up from static electricity is exposed to the pins of an IC, the electrostatic discharge (ESD) protection network on the chip is intended to… Read More





Feature-Selective Etching in SAQP for Sub-20 nm Patterning
Self-aligned quadruple patterning (SAQP) is the most widely available technology used for patterning feature pitches less than 38 nm, with a projected capability to reach 19 nm pitch. It is actually an integration of multiple process steps, already being used to pattern the fins of FinFETs [1] and 1X DRAM [2]. These steps, shown… Read More
Arm Reinforces the Mobile Fortress
Arm did it again. They continue to press their advantage, most recently with an announcement on their 2020 release of cores for mobile applications, in Cortex-A, in what they now call Cortex-X custom cores, in Mali GPUs and in the next generation of their Ethos neural net core.

Misunderstanding the Economic Factors of Cybercrime
A new study by Cambridge Cybercrime Centre titled Cybercrime is (often) boring: maintaining the infrastructure of cybercrime economies concludes that cybercrime is boring and recommends authorities change their strategy to highlight the tedium in order to dissuade the growth of cybercrime.
Warning: Full-blown rant ahead,… Read More
Time for Chip Diplomacy
An industry caught in the crosshairs of geopolitics needs global emeritus leadership
The semiconductor industry is at the epicenter of great power politics. An ascendant China is on a quest for a unified global system with China as the leading power. The United States seeks to maintain its position as leader of the liberal democratic… Read More
Minimizing Power Consumption in Ultra Low Power MCU Based SoCs
When it comes to extremely power sensitive applications such as IoT and edge devices, there is literally an arsenal of power saving techniques that could be used. The tricky part is figuring out which ones to use and how to use them for maximum benefit. This is coupled with the need to not hamper device performance or functionality.… Read More
PLDA Expands Data Interconnect IP Solutions with CXL and Gen-Z Protocol Support
A couple of months ago I introduced PLDA, a new member of the SemiWiki community, with a post about PLDA’s switch IP and its support for PCIe and NVMe solid state disks. Working in the area of high-performance data interconnects requires support for a growing list of standards, standards that continually evolve. The trick is to stay… Read More
What a Difference an Architecture Makes: Optimizing AI for IoT
Last week Mentor hosted a virtual event on designing an AI accelerator with HLS, integrating it together with an Arm Corstone SSE-200 platform and characterizing/optimizing for performance and power. Though in some ways a recap of earlier presentations, there were some added insights in this session, particularly in characterizing… Read More
