Integration Hurdles For Analog And RF In Next-Gen Packages


A rapid increase in wireless connectivity and more sensors, coupled with a shift away from monolithic SoCs toward heterogeneous integration, is driving up the amount of analog/RF content in systems and changing the dynamics within a package. Since the early 2000s, the majority of chips used at the most advanced nodes were systems-on-chip (SoCs). All features had to fit into a single planar S... » read more

Self-Heating Issues Spread


With every new node there are additional physical effects that must be considered, but not all of them are of the same level of criticality. One that is being mentioned more frequently is self-heating. All devices consume power and when they do that, it becomes heat. "In essence, all active devices generate heat as carriers move, creating channels for current to pass through the gates," says... » read more

The Path To Known Good Interconnects


Chiplets and heterogenous integration (HI) provide a compelling way to continue delivering improvements in performance, power, area, and cost (PPAC) as Moore’s Law slows, but choosing the best way to connect these devices so they behave in consistent and predictable ways is becoming a challenge as the number of options continues to grow. More possibilities also bring more potential interac... » read more

3D-IC Reliability Degrades With Increasing Temperature


The reliability of 3D-IC designs is dependent upon the ability of engineering teams to control heat, which can significantly degrade performance and accelerate circuit aging. While heat has been problematic in semiconductor design since at least 28nm, it is much more challenging to deal with inside a 3D package, where electromigration can spread to multiple chips on multiple levels. “Be... » read more
