2.5D Integration: Big Chip Or Small PCB?


Defining whether a 2.5D device is a printed circuit board shrunk down to fit into a package, or is a chip that extends beyond the limits of a single die, may seem like hair-splitting semantics, but it can have significant consequences for the overall success of a design. Planar chips always have been limited by size of the reticle, which is about 858mm2. Beyond that, yield issues make the si... » read more

Re-architecting Hardware For Energy


A lot of effort has gone into the power optimization of a system based on the RTL created, but that represents a small fraction of the possible power and energy that could be saved. The industry's desire to move to denser systems is being constrained by heat, so there is an increasing focus on re-architecting systems to reduce the energy consumed per useful function performed. Making signifi... » read more

Why There Are Still No Commercial 3D-ICs


Building chips in three dimensions is drawing increased attention and investment, but so far there have been no announcements about commercial 3D-IC chips. There are some fundamental problems that must be overcome and new tools that need to be developed. In contrast, the semiconductor industry is becoming fairly comfortable with 2.5D integration, where individual dies are assembled on some k... » read more

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

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

2023: A Good Year For Semiconductors


Looking back, 2023 has had more than its fair share of surprises, but who were the winners and losers? The good news is that by the end of the year, almost everyone was happy. That is not how we exited 2022, where there was overcapacity, inventories had built up in many parts of the industry, and few sectors — apart from data centers — were seeing much growth. The supposed new leaders we... » 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

Making Heterogeneous Integration More Predictable


Experts at the Table: Semiconductor Engineering sat down to discuss problems and potential solutions in heterogeneous integration with Dick Otte, president and CEO of Promex Industries; Mike Kelly, vice president of chiplets/FCBGA integration at Amkor Technology; Shekhar Kapoor, senior director of product management at Synopsys; John Park, product management group director in Cadence's Custom I... » read more

Anatomy Of A System Simulation


The semiconductor industry has greatly simplified analysis by consolidating around a small number of models and abstractions, but that capability is breaking down both at the implementation level and at the system level. Today, the biggest pressure is coming from the systems industry, where the electronic content is a small fraction of what must be integrated together. Systems companies tend... » read more
