Design Challenges Increasing For Mixed-Die Packages


The entire semiconductor ecosystem is starting to tackle a long list of technology and business changes that will be needed to continue scaling beyond Moore's Law, making heterogeneous combinations of die easier, cheaper, and more predictable. There are a number of benefits to mixing die and putting them together in a modular way. From a design standpoint, this approach provides access to th... » read more

Unknowns Driving Up The Cost Of Auto IC Reliability


Automotive chipmakers are considering a variety of options to improve the reliability of ICs used for everything from sensors to artificial intelligence. But collectively they could boost the number of process steps, increase the time spent in manufacturing and packaging, and stir up concerns about the amount of data that needs to be collected, shared, and stored. Accounting for advanced pro... » read more

What Causes Semiconductor Aging?


Semiconductor technology has evolved to the point where no one can assume chips will last forever. If not carefully considered, aging can shorten the life of an IC below the needs for an intended application. Aging is well studied in technology circles, but while others less directly involved may understand at a general level this is a problem, it's not always obvious why. So what exactly ar... » read more

More Manufacturing Issues, More Testing


Douglas Lefever, CEO of Advantest America, sat down with Semiconductor Engineering to talk about changes in test, the impact of advanced packaging, and business changes that are happening across the flow. What follows are excerpts of that discussion. SE: What are the big changes ahead in test? Lefever: It's less about inflection points and more like moving from algebra to calculus in the ... » read more

Data Security Challenges In Automotive


Automakers are scrambling to prevent security breaches and data hacks in new vehicles while simultaneously adding new and increasingly autonomous features into vehicles that can open the door to new vulnerabilities. These two goals are often at odds. As with security in any complex system, nothing is ever completely secure. But even getting a handle on this multilayered issue is a challenge.... » read more

ML Focus Shifting Toward Software


New machine-learning (ML) architectures continue to garner a huge amount of attention as the race continues to provide the most effective acceleration architectures for the cloud and the edge, but attention is starting to shift from the hardware to the software tools. The big question now is whether a software abstraction eventually will win out over hardware details in determining who the f... » read more

Power Grids Under Attack


Cyberattacks are becoming as troublesome to the electrical power grid as natural disasters, and the problem is growing worse as these grids become more connected and smarter. Unlike in the past, when a power outage affected just the electricity supplied to homes and businesses, power grids are becoming core elements of smart cities, infrastructure, and safety-related services. Without power,... » read more

Startup Funding: January 2022


China's startups are the star of the month once again, with more companies based or co-headquartered in the country receiving funding in January 2022 than the rest of the world combined. Exact investment figures for Chinese startups are frequently not reported, but based on minimum amounts given, they raised more than the rest of the world as well. The largest round of the month went to a co... » read more

Next-Gen 3D Chip/Packaging Race Begins


The first wave of chips is hitting the market using a technology called hybrid bonding, setting the stage for a new and competitive era of 3D-based chip products and advanced packages. AMD is the first vendor to unveil chips using copper hybrid bonding, an advanced die-stacking technology that enables next-generation 3D-like devices and packages. Hybrid bonding stacks and connects chips usin... » read more

A New Dimension Of Complexity For IC Design


Full 3D designs involving logic-on-logic are still in the tire-kicking stage, but gaps in the tooling already are showing up. This is especially evident with static timing analysis (STA), which is used to validate a design’s timing performance by checking all possible paths for timing violations. STA issues began popping up particularly with the introduction of hybrid bonding, a bumpless p... » read more
