Many More Hurdles In Heterogeneous Integration


Advanced packaging options continue to stack up in the pursuit of “More than Moore” and higher levels of integration. It has become a place where many high-density interconnects converge, and where many new and familiar problems need to be addressed. The industry’s first foray into fine-pitch multi-die packaging utilized silicon interposers with through-silicon vias (TSVs) to deliver s... » read more

Navigating Heat In Advanced Packaging


The integration of multiple heterogeneous dies in a package is pivotal for extending Moore’s Law and enhancing performance, power efficiency, and functionality, but it also is raising significant issues over how to manage the thermal load. Advanced packaging provides a way to pack more features and functions into a device, increasingly by stacking various components vertically rather than ... » read more

Chip Industry Silos Are Crimping Advances


Change is never easy, but it is more difficult when it involves organizational restructuring. The pace of such restructuring has been increasing over the past decade, and often it is more difficult to incorporate than technological advancements. This is due to the siloed nature of the semiconductor industry, both within the industry itself, and its relationship to surrounding industries. Inc... » read more

Glass Substrates Gain Foothold In Advanced Packages


Glass substrates are starting to gain traction in advanced packages, fueled by the potential for denser routing and higher signal performance than the organic substrates used today. There are still plenty of problems to solve before this approach becomes mainstream. While glass itself is cheap and shares some important physical similarities to silicon, there are challenges with buildup, stre... » read more

Using Deep Data For Improved Reliability Testing


Reliability testing always has been a challenge for semiconductor companies, but it’s becoming much more difficult as devices continue to shrink, as they’re integrated together in advanced packages, and as they’re utilized under different conditions with life expectancy that varies by application and use case. Nir Sever, senior director of business development at proteanTecs, and Luca Mor... » read more

Proprietary Vs. Commercial Chiplets


Large chipmakers are focusing on chiplets as the best path forward for integrating more functions into electronic devices. The challenge now is how to pull the rest of the chip industry along, creating a marketplace for third-party chiplets that can be chosen from a menu using specific criteria that can speed time to market, help to control costs, and behave as reliably as chiplets developed in... » read more

Next-Gen Power Integrity Challenges


Experts at the Table: Semiconductor Engineering sat down to discuss power integrity challenges and best practices in designs at 7nm and below, and in 2.5D and 3D-IC packages, with Chip Stratakos, partner, physical design at Microsoft; Mohit Jain, principal engineer at Qualcomm; Thomas Quan, director at TSMC; and Murat Becer, vice president at Ansys. What follows are excerpts of that conversatio... » read more

Closing The Test And Metrology Gap In 3D-IC Packages


The industry is investing in more precise and productive inspection and testing to enable advanced packages and eventually, 3D ICs. The next generations of aerospace, automotive, smartphone, and wearable tech most likely will be powered by multiple layers of intricately connected silicon, a stark departure from the planar landscapes of traditional integrated circuits. These 3D-ICs, compos... » read more

Fluid Dispensing For Packaging Today’s Devices


Fluid dispensing systems are evolving in order to address the challenges that system-in-package (SiP) and micromechanical systems (MEMS) packages face, especially in regard to tight geometries and assembly processes. These packages, used in smartphones, have become more miniaturized, and as a result, have created added value in the market. However, they include a variety of small dies or dev... » read more

AI Accelerator Architectures Poised For Big Changes


AI is driving a frenzy of activity in the chip world as companies across the semiconductor ecosystem race to include AI in their product lineup. The challenge now is how to make AI run faster, use less energy, and to be able to leverage it from the edge to the data center — particularly with the rollout of large language models. On the hardware side, there are two main approaches for accel... » read more
