Design Considerations and Recent Advancements in Chiplets (UC Berkeley/ Peking University)


A new technical paper titled "Automated Design of Chiplets" was published by researchers at UC Berkeley and Peking University. Abstract: "Chiplet-based designs have gained recognition as a promising alternative to monolithic SoCs due to their lower manufacturing costs, improved re-usability, and optimized technology specialization. Despite progress made in various related domains, the des... » read more

Chiplet Security Risks Underestimated


The semiconductor ecosystem is abuzz with the promise of chiplets, but there is far less attention being paid to security in those chiplets or the heterogeneous systems into which they will be integrated. Disaggregating SoCs into chiplets significantly alters the cybersecurity threat landscape. Unlike a monolithic multi-function chip, which usually is manufactured using the same process tech... » read more

Mechanical Challenges Rise With Heterogeneous Integration


Companies integrating multiple chips or chiplets into a package will need to address structural and other mechanical engineering issues, but gaps in the design tools, new materials and interconnect technologies, and a shortage of expertise are making it difficult to address those issues. Throughout most of the history of the semiconductors, few people outside of foundries worried about struc... » read more

True 3D Is Much Tougher Than 2.5D


Creating real 3D designs is proving to be much more complex and difficult than 2.5D, requiring significant innovation in both technology and tools. While there has been much discussion about 3D designs, there are multiple interpretations about what 3D entails. This is more than just semantics, however, because each packaging option requires different design approaches and technologies. And a... » read more

The Race Toward Mixed-Foundry Chiplets


Creating chiplets with as much flexibility as possible has captured the imagination of the semiconductor ecosystem, but how heterogeneous integration of chiplets from different foundries will play out remains unclear. Many companies in the semiconductor ecosystem are still figuring out how they will fit into this heterogeneous chiplet world and what issues they will need to solve. While near... » read more

Mini-Consortia Forming Around Chiplets


Mini-consortia for chiplets are sprouting up across the industry, driven by demands for increasing customization in tight market windows and fueled by combinations of hardened IP that have been proven in silicon. These loosely aligned partnerships are working to develop LEGO-like integration models for highly specific applications and end markets. But they all are starting small, because it'... » read more

Room-Temperature Metal Bonding Technology That Facilitates The Fabrication of 3D-ICs & 3D Integration With Heterogeneous Devices


A technical paper titled "Room-Temperature Direct Cu Semi-Additive Plating (SAP) Bonding for Chip-on-Wafer 3D Heterogenous Integration With μLED" was published by researchers at Tohoku University in Japan. Abstract: "This letter describes a direct Cu bonding technology to there-dimensionally integrate heterogeneous dielets based on a chip-on-wafer configuration. 100- μm -cubed blue μ LED... » read more

Panel Tackles Chiplet Packaging Challenges


QP Technologies recently exhibited at the first Chiplet Summit, held January 24-26 in San Jose, California. Dick Otte, CEO of our parent company Promex Industries, participated on a panel titled “Best Packaging for Chiplets Today.” Moderated by Nobuki Islam with JCET Group, the packaging panel also included Daniel Lambalot, Alphawave Semi; Laura Mirkarimi, Adeia; Syrus Ziai, Eliyan; and Mik... » 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

MIPI’s Focus Widens


Ashraf Takla, president and CEO of Mixel, sat down with Semiconductor Engineering to talk about the evolution of MIPI, from mobile displays to automotive, chiplets, and how the standard is evolving to keep up with increasing data volumes. SE: There has been a lot of activity around MIPI in automotive. What's driving that? Takla: One of the early use-cases for MIPI, after Mobile has been ... » read more
