3D IC Podcast episode 12 insights: The thermal challenge in 3D IC design: Understanding and managing heat in modern semiconductor packaging
As semiconductor designs become more complex and compact, thermal management has evolved from an afterthought to a critical design consideration. This transformation has been driven by the increasing power densities in modern 3D IC designs, which are approaching levels comparable to the surface of the sun. This isn’t hyperbole – it’s a stark reality that’s forcing a fundamental shift in how we approach chip design.
Traditionally, thermal analysis was an afterthought, often reduced to back-of-the-envelope calculations performed late in the design process. But with 2.5D and 3D architectures packing multiple chiplets in increasingly close proximity, this approach is no longer viable. The heat generated by these densely packed components must be managed effectively, not just for performance but for basic functionality and reliability.
