Challenges In Backside Power Delivery


One of the key technologies to enable scaling below 3nm involves delivering of power on the backside of a chip. This novel approach enhances signal integrity and reduces routing congestion, but it also creates some new challenges for which today there are no simple solutions. Backside power delivery (BPD) eliminates the need to share interconnect resources between signal and power lines on t... » read more

Where All The Semiconductor Investments Are Going


Companies and countries are funneling huge sums of money into semiconductor manufacturing, materials, and research — at least a half-trillion dollars over the next decade, and maybe much more — to guarantee a steady supply of chips and know-how to support growth across a wide swath of increasingly data-centric industries. The build-out of a duplicate supply chain that can guarantee capac... » read more

Blog Review: Nov. 16


Siemens EDA's Jake Wiltgen explains the difference between transient and permanent faults when designing to the ISO 26262 standard, including where they come from and key ways to protect against them. Synopsys' Vikas Gautam points to how the economics of designing large SoCs is driving chiplet-based designs and the need for die-to-die standards such as UCIe, along with the key protocol verif... » read more

Research Bits: Nov. 15


Low temperature 3D bonding Scientists from Osaka University developed a new method for the direct three-dimensional bonding of copper electrodes using silver layers. The method works at low temperatures and does not require external pressure. "Our process can be performed under gentle conditions, at relatively low temperatures and without added pressure, but the bonds were able to withstand... » read more

Week In Review: Semiconductor Manufacturing, Test


U.S. President Joe Biden appears ready to increase pressure on Japan and the Netherlands to help block the flow of advanced chip technology to China, where it can be used to develop cutting-edge weapons. "You will see Japan and Netherlands follow our lead," U.S. Commerce Secretary Gina Raimondo told CNBC. Japan plans to budget ¥350 billion ($2.38 billion) in a research collaboration with th... » read more

Blog Review: Nov. 9


Cadence's Claire Ying finds that the latest update to CXL, which introduced memory-centric fabric architectures and expanded capabilities for improving scale and optimizing resource utilization, could change how some of the world’s largest data centers and fastest supercomputers are built. Synopsys' Gervais Fong and Morten Christiansen examine the latest updates in the USB 80Gbps specifica... » read more

Next Steps For Improving Yield


Chipmakers are ramping new tools and methodologies to achieve sufficient yield faster, despite smaller device dimensions, a growing number of systematic defects, immense data volumes, and massive competitive pressure. Whether a 3nm process is ramping, or a 28nm process is being tuned, the focus is on reducing defectivity. The challenge is to rapidly identify indicators that can improve yield... » read more

Test Connections Clean Up With Real-Time Maintenance


Test facilities are beginning to implement real-time maintenance, rather than scheduled maintenance, to reduce manufacturing costs and boost product yield. Adaptive cleaning of probe needles and test sockets can extend equipment lifetimes and reduce yield excursions. The same is true for load board repair, which is moving toward predictive maintenance. But this change is much more complicate... » read more

Week In Review: Semiconductor Manufacturing, Test


Nikkei Asia reports the U.S. is urging allies, including Japan, to restrict exports of advanced semiconductors and related technology to China. The U.S. holds 12% of the global semiconductor market, Japan has a 15% share, while Taiwan and South Korea each have about a 20% share. Some U.S. companies have called for other countries to adopt U.S.-style export curbs, arguing it is unfair for only A... » read more

AI Feeds Vision Processor, Image Sensor Boom


Vision systems are rapidly becoming ubiquitous, driven by big improvements in image sensors as well as new types of sensors. While the sensor itself often is developed using mature-node silicon, increasingly it is connected to vision processors developed at the most advanced process nodes. That allows for the highest performance per watt, and it also allows designs to incorporate AI accelera... » read more
