Degradation Monitoring – From Vision to Reality


Reliability physics has historically focused on models for time-to-failure, but that approach is reaching its limit. Those models generally were developed using data gathered from very simple test structures that could be stressed to failure. Today, with electronics playing a such a critical role in our everyday life, failures are no longer an option. The underlying ICs being implemented call f... » read more

Using Better Data To Shorten Test Time


The combination of machine learning plus more sensors embedded into IC manufacturing equipment is creating new possibilities for more targeted testing and faster throughput for fabs and OSATs. The goal is to improve quality and reduce the cost of manufacturing complex chips, where time spent in manufacturing is ballooning at the most advanced nodes. As the number of transistors on a die incr... » read more

Signoff-Compatible CDC


Tanveer Singh, senior staff consulting applications engineer at Synopsys, explains why netlist clock domain crossing is now an essential complement to RTL CDC, why CDC issues are worse at advanced nodes and in AI chips, and why dealing with CDC effectively is becoming a competitive requirement for performance and low power. » read more

Material Choices In Printed Temperature Sensors


Vijaya Kayastha, lead device development engineer at Brewer Science, talks about what’s needed for printed temperature sensors, what happens when there are impurities in the materials, how these sensors respond to stress, and how costs compare to traditional sensors. » read more

Factoring Reliability Into Chip Manufacturing


Making chips that can last two decades is possible, even if it's developed at advanced process nodes and is subject to extreme environmental conditions, such as under the hood of a car or on top of a light pole. But doing that at the same price point as chips that go into consumer electronics, which are designed to last two to four years, is a massively complex challenge. Until a couple of y... » read more

Power, Reliability And Security In Packaging


Semiconductor Engineering sat down to discuss advanced packaging with Ajay Lalwani, vice president of global manufacturing operations at eSilicon; Vic Kulkarni, vice president and chief strategist in the office of the CTO at ANSYS; Calvin Cheung, vice president of engineering at ASE; Walter Ng, vice president of business management at UMC; and Tien Shiah, senior manager for memory at Samsun... » read more

Circuit Aging Becoming A Critical Consideration


Circuit aging was considered somebody else's problem when most designs were for chips in consumer applications, but not anymore. Much of this reflects a shift in markets. When most chips were designed for consumer electronics, such as smart phones, designs typically were replaced every couple of years. But with the mobile phone market flattening, and as chips increasingly are used in automot... » read more

BiST Grows Up In Automotive


Test concepts and methods that have been used for many years in traditional semiconductor and SoC design are now being leveraged for automotive chips, but they need to be adapted and upgraded to enable monitoring of advanced automotive systems during operation of a vehicle. Automotive and safety critical designs have very high quality, reliability, and safety requirements, which pairs pe... » read more

Test Moving Forward And Backward


Test, once considered an important but rather mundane way of separating good chips from the not-so-good and the total rejects, is taking on a whole new life. After decades of largely living in the shadows behind design and advancements in materials and lithography, test has quietly shifted into a much more critical and more public role. But it has taken several rather significant shifts acro... » read more
