Optimizing Data Movement
By Ann Mutschler - 29 May, 2025 - Comments: 0

Demand for new and better AI models is creating an insatiable demand for more processing power and much better data throughput, but it's also creating a slew of new challenges for which there are not always good solutions. The key here is figuring out where bottlenecks might crop up in complex chips and advanced packages. This involves a clear understanding of how much bandwidth is required ... » read more

A Balanced Approach To Verification
By Brian Bailey - 29 May, 2025 - Comments: 0

First-time chip success rates are dropping, primarily due to increased complexity and attempts to cut costs. That means management must take a close look at their verification strategies to determine if they are maximizing the potential of their tools and staff. Using simulation to demonstrate that a design exhibits a required behavior has been the cornerstone of functional verification sinc... » read more

Executive Outlook: Chiplets, 3D-ICs, and AI
By Ed Sperling - 29 May, 2025 - Comments: 0

Semiconductor Engineering sat down to discuss chiplets and the challenges of moving to 3D-ICs with Bill Mullen, Ansys fellow; John Ferguson, senior director of product management at Siemens EDA; Chris Mueth, senior director of new markets and strategic initiatives at Keysight; Albert Zeng, senior engineering group director at Cadence; Anand Thiruvengadam, senior director and head of AI product ... » read more

Cooling Chips Still A Top Challenge
By Bryon Moyer - 22 May, 2025 - Comments: 0

Increasing levels of semiconductor integration means more work needs to be done in smaller spaces, which in turn generates more heat that needs to be dissipated. Managing heat dissipation in advanced node dies and in multi-die assemblies is critical to their functionality and their longevity. And while much of the focus has been on improving power efficiency, which reduces the rate of power ... » read more

Mask Complexity, Cost, And Change
By Gregory Haley - 22 May, 2025 - Comments: 0

Experts at the Table: As leading-edge lithography nodes push further into EUV and beyond, mask-making has become one of the most critical and costly aspects of semiconductor manufacturing. At the same time, non-EUV applications are stretching the lifetime of older tools and processes, challenging the industry to find new solutions for both ends of the spectrum. Semiconductor Engineering sat dow... » read more

Advanced Packaging Depends On Materials And Co-Design
By Katherine Derbyshire - 22 May, 2025 - Comments: 0

Multi-die assemblies offer significant opportunities to boost performance and reduce power, but these complex packages also introduce a number of new challenges, including die-to-RDL misalignment, evolving warpage profiles, and CTE mismatch. Heterogeneous integration — an umbrella term that covers many different applications and packaging requirements — holds the potential to combine com... » read more

Future-proofing AI Models
By Ann Mutschler - 21 May, 2025 - Comments: 0

Experts At The Table: Making sure AI accelerators can be updated for future requirements is becoming essential due to the rapid introduction of new models. Semiconductor Engineering sat down to discuss the challenges of future-proofing these designs with Marc Meunier, director of ecosystem development at Arm; Jason Lawley, director of product marketing for AI IP at Cadence; Paul Karazuba, vic... » read more

More Data, More Redundant Interconnects
By Ed Sperling - 19 May, 2025 - Comments: 0

The proliferation of AI dramatically increases the amount of data that needs to be processed, stored, and moved, accelerating the aging of signal paths through which that data travels and forcing chipmakers to build more redundancy into the interconnects. In the past, nearly all redundant data paths were contained within a planar chip using a relatively thick silicon substrate. But as chipma... » read more

Development Flows For Chiplets
By Brian Bailey - 15 May, 2025 - Comments: 2

Chiplets offer a huge leap in semiconductor functionality and productivity, just like soft IP did 40 years ago, but a lot has to come together before that becomes reality. It takes an ecosystem, which is currently very rudimentary. Today, many companies have hit the reticle limit and are forced to move to multi-die solutions, but that does not create a plug-and-play chiplet market. These ear... » read more

AI Accelerators Moving Out From Data Centers
By Ann Mutschler - 15 May, 2025 - Comments: 0

Experts At The Table: The explosion in AI data is driving chipmakers to look beyond a single planar SoC. Semiconductor Engineering sat down to discuss the need for more computing and the expanding role of chiplets with Marc Meunier, director of ecosystem development at Arm; Jason Lawley, director of product marketing for AI IP at Cadence; Paul Karazuba, vice president of marketing at Expedera; ... » read more
