Speeding Down Memory Lane With Custom HBM


With the goal of increasing system performance per watt, the semiconductor industry is always seeking innovative solutions that go beyond the usual approaches of increasing memory capacity and data rates. Over the last decade, the High Bandwidth Memory (HBM) protocol has proven to be a popular choice for data center and high-performance computing (HPC) applications. Even more benefit can be rea... » read more

Automation And AI Improve Failure Analysis


When a chip malfunctions it’s the job of the failure analysis engineer to determine how it failed or significantly deviated from its key performance metrics. The cost of failure in the field can be huge in terms of downtime, recalls, damage to a company’s reputation, and more. For these reasons, chipmakers take customer returns very seriously, focusing resources to quickly get to the bot... » read more

Unlocking The Value Of Yield


Have you stopped to consider the impact of yield on your overall product cost? Of course you did, when you considered your yield targets and set your product goals. But is it good enough to stop once the goals are achieved, or should you find ways to drive additional value into your organization once production has begun? What is the value of a 1% improvement in product yield? The short answer ... » read more

Cutting IC Manufacturing Costs By Combining Data


Experts at the Table: Semiconductor Engineering sat down to discuss the benefits of incorporating financial data into fab floor decision-making, including what kind of cost data is most useful, with Dieter Rathei, CEO of DR Yield; Jon Holt, senior director of product management at PDF Solutions, Alex Burlak, vice president of advanced analytics and test at proteanTecs; and Dirk de Vries, techni... » read more

Reversible Chain Diagnosis


For advanced technologies, the industry is seeing very complicated silicon defect types and defect distribution. One consequence is that scan chain diagnosis becomes more difficult. To improve the resolution of scan chain diagnosis, Tessent Diagnosis can use new scan chain test patterns to leverage a reversible scan chain architecture. This paper describes the novel scan chain architecture t... » read more

Failure To Launch


Failure analysis (FA) is an essential step for achieving sufficient yield in semiconductor manufacturing, but it’s struggling to keep pace with smaller dimensions, advanced packaging, and new power delivery architectures. All of these developments make defects harder to find and more expensive to fix, which impacts the reliability of chips and systems. Traditional failure analysis techniqu... » read more

Full-Chip Voltage Contrast Inference Using Deep Learning; You Only Look Once: Voltage Contrast (YOLO-VC)


Abstract: The electron beam inspection methodology for voltage contrast (VC) defects has been widely adopted in the early stages of sub-10nm logic and memory technology development, as well as in new product introductions. However, due to throughput limitations, full-chip inspection at the 300mm wafer scale remains impractical for yield ramp and production applications. To address this challeng... » read more
