5nm Vs. 3nm


Foundry vendors are readying the next wave of advanced processes, but their customers will face a myriad of confusing options—including whether to develop chips at 5nm, wait until 3nm, or opt for something in between. The path to 5nm is well-defined compared with 3nm. After that, the landscape becomes more convoluted because foundries are adding half-node processes to the mix, such as 6nm ... » read more

Advanced Process Control


David Fried, vice president of computational products at Lam Research, looks at shrinking tolerances at advanced processes, how that affects variation in semiconductor manufacturing, and what can be done to achieve the benefits of scaling without moving to new transistor architectures. » read more

Weighing Wafers Simplifies Metrology


Building semiconductors is an incredibly exacting process, with critical dimensions posing significant equipment challenges—and with the possibility that small process excursions can cause the yield to decrease. For this reason, it has always been important to measure and monitor the most critical process steps to ensure that no further processing is done on a faulty lot and so that equipment... » read more

Week In Review: Manufacturing, Test


Market research In the second quarter of 2019, TrendForce said that the top-5 foundry rankings remained identical with that of last year. But sixth to tenth place showed some changes. Who is up or down in what is a tough business climate? Global fab equipment spending will rebound in 2020, growing 20% to $58.4 billion after dropping 19% to $48.4 billion in 2019, according to SEMI. However, ... » read more

Inspection, Metrology Challenges Grow For SiC


Inspection and metrology are becoming more critical in the silicon carbide (SiC) industry amid a pressing need to find problematic defects in current and future SiC devices. Finding defects always has been a challenging task for SiC devices. But it’s becoming more imperative to find killer defects and reduce them as SiC device vendors begin to expand their production for the next wave of a... » read more

Week In Review: Manufacturing, Test


Market research IC Insights has released its forecast for chips in terms of applications. Communications is still the biggest IC market, but automotive is growing the fastest. In its first forecast of artificial intelligence (AI) edge processors, International Data Corp. (IDC) estimates that worldwide shipments of AI-optimized processors for edge systems will reach 340.1 million units in 20... » read more

SiC Demand Growing Faster Than Supply


The silicon carbide (SiC) industry is in the midst of a major expansion campaign, but suppliers are struggling to meet potential demand for SiC power devices and wafers in the market. In just one example of the expansion efforts, Cree plans to invest up to $1 billion to increase its SiC fab and wafer capacities. As part of the plan, Cree is developing the world’s first 200mm (8-inch) SiC f... » read more

3D NAND Race Faces Huge Tech And Cost Challenges


Amid the ongoing memory downturn, 3D NAND suppliers continue to race each other to the next technology generations with several challenges and a possible shakeout ahead. Micron, Samsung, SK Hynix and the Toshiba-Western Digital duo are developing 3D NAND products at the next nodes on the roadmap, but the status of two others, Intel and China’s Yangtze Memory Technologies Co. (YMTC), is les... » read more

Controlling Variability And Cost At 3nm And Beyond


Richard Gottscho, executive vice president and CTO of Lam Research, sat down with Semiconductor Engineering to talk about how to utilize more data from sensors in manufacturing equipment, the migration to new process nodes, and advancements in ALE and materials that could have a big impact on controlling costs. What follows are excerpts of that conversation. SE: As more sensors are added int... » read more

Week In Review: Manufacturing, Test


Market research In terms of overall IC sales, Intel has replaced Samsung as the number one quarterly semiconductor supplier in 4Q18 after losing the lead spot to Samsung in 2Q17, according to IC Insights. “While Samsung held the full-year number one ranking in 2017 and 2018, Intel is forecast to easily recapture the number one ranking for the full-year of 2019, a position it previously held ... » read more
