What’s After FinFETs?


Chipmakers are readying their next-generation technologies based on 10nm and/or 7nm finFETs, but it's still not clear how long the finFET will last, how long the 10nm and 7nm nodes for high-end devices will be extended, and what comes next. The industry faces a multitude of uncertainties and challenges at 5nm, 3nm and beyond. Even today, traditional chip scaling continues to slow as process ... » read more

The Week In Review: Manufacturing


Fab equipment ASML posted strong sales in the quarter and is apparently nearly sold out of scanners based on extreme ultraviolet (EUV) lithography, according to analysts. “ASML posted strong 2Q results and 2Q guidance, providing further evidence that demand remains high for semiconductor equipment,” said Weston Twigg, an analyst with KeyBanc Capital Markets, in a research note. “Demand d... » read more

Is 7nm The Last Major Node?


A growing number of design and manufacturing issues are prompting questions about what scaling will really look like beyond 10/7nm, how many companies will be involved, and which markets they will address. At the very least, node migrations will go horizontally before proceeding numerically. There are expected to be more significant improvements at 7nm than at any previous node, so rather th... » read more

Filtering Out Fab Problems


Bertrand Loy, president and CEO of Entegris, sat down to discuss the semiconductor industry, process challenges and filter technology with Semiconductor Engineering. What follows are excerpts of that conversation. SE: What is the outlook for the IC industry? Loy: A lot of positive things are happening. Eighty percent of what we do are consumables, which would be chemistries and filters. ... » read more

The Week In Review: Manufacturing


Market research SEMI has released its mid-year forecast at Semicon West. SEMI reported that worldwide sales of new semiconductor manufacturing equipment are projected to increase by 19.8% to a total of $49.4 billion in 2017, marking the first time that the semiconductor equipment market has exceeded the market high of $47.7 billion set in 2000. In 2018, 7.7% growth is expected, resulting in an... » read more

Manufacturing Bits: June 27


World’s brightest laser The University of Nebraska-Lincoln has set the unofficial record for the world’s brightest laser. Researchers have focused a laser at a brightness of 1 billion times greater than the surface of the sun. This feat was accomplished using the so-called Diocles Laser at the University of Nebraska-Lincoln. The laser has a combination of peak power and a repetition ra... » read more

Inside Chip R&D


Semiconductor Engineering sat down to discuss R&D challenges, EUV and other topics with Luc Van den hove, president and chief executive of Imec, an R&D organization in Belgium. What follows are excerpts of that conversation. SE: Clearly, Moore’s Law is slowing down. The traditional process cadence is extending from 2 years to roughly 2.5 to 3 years. Yet, R&D is not slowing down, right? ... » read more

New BEOL/MOL Breakthroughs?


Chipmakers are moving ahead with transistor scaling at advanced nodes, but it's becoming more difficult. The industry is struggling to maintain the same timeline for contacts and interconnects, which represent a larger portion of the cost and unwanted resistance in chips at the most advanced nodes. A leading-edge chip consists of three parts—the transistor, contacts and interconnects. The ... » read more
