Working With Chiplets

By Ed Sperling - 02 Oct, 2024 - Comments: 0

The usual method of migrating to the next process node to cram more features onto a piece of silicon no longer works. It's too expensive, and too limited for most applications. The path forward is now heterogeneous chiplets targeted at specific markets, and while logic will continue to scale, other features are being separated out into chiplets developed using different process technologies. Th... » read more

Legacy Process Nodes Going Strong

By Bryon Moyer - 23 Jul, 2024 - Comments: 0

While all eyes tend to focus on the leading-edge silicon nodes, many mature nodes continue to enjoy robust manufacturing demand. Successive nodes stopped reducing die cost at around the 20nm node. “In the finFET era of processes, esoteric process requirements necessary to move technology forward with each generation have added significant cost and complexity,” explained Andrew Appleby, p... » read more

Who Will Regulate Data Exchanges In Chiplets?

By Ed Sperling - 17 Aug, 2023 - Comments: 0

Scaling is still important when it comes to logic and low power, but it's no longer the main avenue for improving performance. What used to be a single chip, comprised of various IP blocks and components on a single SoC, is giving way to a heterogeneous collection of chiplets — at least for the big chipmakers and system companies at the leading edge. Chiplets are currently the best solutio... » read more

Will CFETs Help The Industry Go Vertical?

By Katherine Derbyshire - 15 Jun, 2023 - Comments: 0

Device scaling is getting much harder at each new process node. Even defining what it means is becoming a challenge. In the past, gate length and metal pitch went down and device density went up. Today, this is much harder for several reasons: • Short channel effects limit gate-length scaling; • Parasitic effects limit device density, and • Metal resistance limits metal pitch. So r... » read more

Memory Evolution Drives Requirements For Design Technology Co-Optimization

By Ricardo Borges - 15 Jul, 2022 - Comments: 0

By Ricardo Borges and Anand Thiruvengadam As new technology nodes have become available, memory has been one of the most aggressive semiconductor applications to adopt advanced process technology. The relentless demand by users of electronic devices for more memory has ensured that investments in new nodes and processes would be quickly repaid by massive sales volumes. As each new node came ... » read more

Why It’s So Difficult — And Costly — To Secure Chips

By Ed Sperling - 02 Dec, 2021 - Comments: 0

Rising concerns about the security of chips used in everything from cars to data centers are driving up the cost and complexity of electronic systems in a variety of ways, some obvious and others less so. Until very recently, semiconductor security was viewed more as a theoretical threat than a real one. Governments certainly worried about adversaries taking control of secure systems through... » read more

Semiconductor Engineering sat down to talk about design challenges in advanced packages and nodes with John Lee, vice president and general manager for semiconductors at Ansys; Shankar Krishnamoorthy, general manager of Synopsys' Design Group; Simon Burke, distinguished engineer at Xilinx; and Andrew Kahng, professor of CSE and ECE at UC San Diego. This discussion was held at the Ansys IDEAS co... » read more

What’s Changing In DRAM

By Ed Sperling - 15 Sep, 2021 - Comments: 0

Most of the attention in chip scaling has been focused on logic and on-chip memory, but off-chip memory is starting to encounter problems, as well. David Fried, vice president of computational products at Lam Research, looks at the impact of shrinking features and increasing density, including variation, thermal effects and aging, as well as effects such as micro-loading and DRAM stacking. » read more

Tradeoffs To Improve Performance, Lower Power

By Ann Mutschler - 11 Mar, 2021 - Comments: 0

Generic chips are no longer acceptable in competitive markets, and the trend is growing as designs become increasingly heterogeneous and targeted to specific workloads and applications. From the edge to the cloud, including everything from vehicles, smartphones, to commercial and industrial machinery, the trend increasingly is on maximizing performance using the least amount of energy. This ... » read more

Chiplets For The Masses

By Brian Bailey - 03 Mar, 2021 - Comments: 2

Chiplets are a compelling technology, but so far they are available only to a select few players in the industry. That's changing, and the industry has taken little steps to get there, but timing for when you will be able to buy a chiplet to integrate into your system remains uncertain. While new fabrication nodes continue to be developed, scaling is coming to an end, be it for physical or e... » read more
