How To Plan And Conduct Highly Accelerated Life Testing


Assessing the robustness of an electronic product is integral to successful design and performance. Highly accelerated life testing (HALT) is an important testing tool for this purpose, and its effectiveness can be maximized through careful planning prior to setup and detailed execution. What is HALT? HALT is the process of applying increased stressors to an electronic device to force failure... » read more

IC Stresses Affect Reliability At Advanced Nodes


Thermal-induced stress is now one of the leading causes of transistor failures, and it is becoming a top focus for chipmakers as more and different kinds of chips and materials are packaged together for safety- and mission-critical applications. The causes of stress are numerous. In heterogeneous packages, it can stem from multiple components composed of different materials. “These materia... » read more

According to the abstract "In this work, the effect of thermomechanical stress on the failure of multilayered thin films on Si substrates was studied using analytical calculations and various thermomechanical tests." ... » read more

New Issues In Advanced Packaging


Advanced packaging is gaining in popularity as the cost and complexity of integrating everything onto a planar SoC becomes more difficult and costly at each new node, but ensuring that these packaged die function properly and yield sufficiently isn't so simple. There are a number of factors that are tilting more of the the semiconductor industry toward advanced [getkc id="27" kc_name="packag... » read more

The Evolving Thermal Landscape


Managing heat in chips is becoming a precision balancing act at advanced nodes and with advanced packaging. While it's important to ensure that temperatures don't rise high enough to cause reliability problems, adding too much circuitry to control heat can reduce performance and lower energy efficiency. The most common approach to dealing with these issues is thermal simulation, which requir... » read more

Challenges In IC And Electronic Systems Verification


Power efficiency, unrealistic schedules, and cost-down considerations are increasingly the top challenges design teams must meet to deliver next generation electronic systems, whether it is for the mobile, server, or automotive market. In addition, a successful chip tapeout does not guarantee the eventual end-product’s success—there are many variables to take into account. In the first p... » read more
