Coming In Hot: Requirements For Successful Thermal Management In 3D-IC

As the speed, density, and capabilities of electronics have all increased, power has become a first order driver in almost all electronic systems. For instance, it’s well recognized that heat is often the number one limiting factor in 3D-IC design. High-speed chips stacked close together in a small housing cause things to heat up fast. One of the most common designer responses to overheating ... » read more

Thermal Cycling Failure In Electronics

Each time a device is turned off and on, its temperature changes. (Just think about how often your phone lights up all day.) Energy flowing through several layers of tightly stacked materials causes devices to heat up, then rapidly cool down. This repeated oscillation between temperatures over the lifetime of a device is called thermal cycling. Why thermal management is important Thermal cycl... » read more

Thermal Floorplanning For Chips

Heat management is becoming crucial to an increasing number of chips, and it's one of a growing number of interconnected factors that must be considered throughout the entire development flow. At the same time, design requirements are exacerbating thermal problems. Those designs either have to increase margins or become more intelligent about the way heat is generated, distributed, and dissi... » read more

Mapping Heat Across A System

Thermal issues are becoming more difficult to resolve as chip features get smaller and systems get faster and more complex. They now require the integration of technologies from both the design and manufacturing flows, making design for power and heat a much broader problem. This is evident with the evolution of a smart phone. Phones sold 10 years ago were very different devices. Functionali... » read more

Recent Advances in Thermal Metamaterials and Their Future Applications for Electronics Packaging

Abstract: "Thermal metamaterials exhibit thermal properties that do not exist in nature but can be rationally designed to offer unique capabilities of controlling heat transfer. Recent advances have demonstrated successful manipulation of conductive heat transfer and led to novel heat guiding structures such as thermal cloaks, concentrators, etc. These advances imply new opportunities to gui... » read more

Development Of An Extremely High Thermal Conductivity TIM For Large Electronics Packages In 4th Industrial Revolution Era

The capability and diversity of high-performance microprocessors is increasing with each process technology generation to meet increasing application demands. The cooling designs for these chips must deal with larger temperature gradients across the die than previous generations. Dissipation of the thermal energy from heat generating parts to a heat sink via conduction occurs through a thermal ... » read more
