A research team at Chalmers is working with carbon nanotubes as conductive material for through-silicon vias. Carbon nanotubes are going to be the most reliable of all conductive materials if it is possible to use them on a large scale. This is the opinion of Kjell Jeppsson, a member of the research team. The researchers have demonstrated that two chips can be vertically … [Read more...]

New Method for Enhancing Thermal Conductivity Could Cool Computer Chips
The surprising discovery of a new way to tune and enhance thermal conductivity gives engineers a new tool for managing thermal effects in smart phones and computers, lasers and a number of other powered devices. The finding was made by a group of engineers headed by Deyu Li, associate professor of mechanical engineering at Vanderbilt University. Li and his collaborators … [Read more...]
Calculation Corner: Transient Thermal Modeling of a High-Power IC Package, Part 1
Part II can be found here. There is an increasing need for calculating integrated circuit temperatures during conditions of changing chip power. Varying computer workloads and the implementation of power-saving strategies are leading to greater variability in chip power levels than in the past. As reliability requirements get more stringent there are growing concerns about the … [Read more...]
Efficient Electro-Thermal Simulation of Power Semiconductor Devices via Model Order Reduction
Thermal management is an increasingly important consideration in the development of power electronic systems. Electro-thermal simulation is required at the system level in order to ensure under realistic loads the fulfillment of thermal requirements, which strongly influence the performance, reliability and efficiency. A significant modeling issue is to obtain a compact but … [Read more...]
The Increasing Challenge of Data Center Design and Management: Is CFD a Must?
Data centers have been cooled for many years by delivering cool air to the IT equipment via the room. One of the key advantages of this approach is the flexibility that it provides the owner/operator in terms of equipment deployment. In principle all that is necessary is to determine the maximum power consumption of the equipment and provide an equivalent amount of cooling to … [Read more...]
