On (the Lack of) Thermal Education
Some like it hot, others do not. And those others for sure include the designers of products that contain electronics. There is a growing need to educate designers who are involved with the undesired side-effects of heat-dissipating components. We often see the following situation. At some moment in time, it is ascertained that a product is getting too hot, and if it turns out … [Read more...]
Numerical Simulation of Complex Submicron Devices
Introduction Significant increases in temperature are believed to contribute to losses in reliability and performance, and can present serious complications to thermal management. The net thermal effect depends on a combination of factors related to the feature size, power densities, and material properties. In semiconductor devices, higher heat flux densities can result from … [Read more...]
When Moore Is Less: Exploring the 3rd Dimension in IC Packaging
Introduction As consumers of electronics we have become spoiled. We not only expect our electronic devices to get smaller, faster, more functional, cheaper, more interconnected, and more reliable, we actually demand it. It would not be a pretty picture either for the consumer or the electronics industry if suddenly the design of our electronic gadgets became static. At this … [Read more...]
The Audacity of Engineering
At the time of this writing (mid-November), it appears that significant progress has been made toward avoiding a global financial collapse and that we now have a good chance of avoiding that fate. Unfortunately, it is now clear that, no matter how the credit markets fare, there will be a recession. Even after the world economy picks up again, the world will certainly face an … [Read more...]
