Factoring Reliability Into Chip Manufacturing

By Ed Sperling - 20 Jun, 2019 - Comments: 0

Making chips that can last two decades is possible, even if it's developed at advanced process nodes and is subject to extreme environmental conditions, such as under the hood of a car or on top of a light pole. But doing that at the same price point as chips that go into consumer electronics, which are designed to last two to four years, is a massively complex challenge. Until a couple of y... » read more

The Arm-Huawei Disconnect

By Ed Sperling - 23 May, 2019 - Comments: 0

Arm's move to stop licensing its processor IP to HiSilicon, the captive chipmaker for Huawei, has set off a panic across the semiconductor industry. While the underlying threat to the entire chip industry is very real, many of the conclusions being drawn about this move are misleading or just plain wrong. When the U.S. government blacklisted Huawei, it imposed export restrictions on shipping... » read more

The Precision Knob

By Ed Sperling - 18 Apr, 2019 - Comments: 0

Precision used to be a goal, but increasingly it is being used as a tool. This is true for processing and algorithms, where less precision can greatly improve both performance and battery life. And it is true in manufacturing, where more precision can help minimize the growing impact of variation. Moreover, being able to dial precision up or down can help engineers see the impact on a system... » read more

A Different Kind Of Material World

By Ed Sperling - 21 Mar, 2019 - Comments: 1

The semiconductor manufacturing world is poised for big change, and the driver will be materials. Materials always have been a critical factor in semiconductors. Silicon is so important that an entire region of California is named after it. Rare earths have raised fears about nationalistic monopolies. And the shift from aluminum to copper interconnects at 130nm caused one of the most painful... » read more

The Mighty Sensor In The Fab

By Ed Sperling - 21 Feb, 2019 - Comments: 1

The days of scheduled maintenance on fab equipment are coming to an end. In fact, the entire service model as we know it is about to undergo a mammoth change. The addition of more sensors into manufacturing equipment may seem like an evolutionary step, but the impact is going to be much more significant than it might appear. Rather than just alerting fab managers or equipment makers when a p... » read more

Variation’s Long Tentacles

By Ed Sperling - 24 Jan, 2019 - Comments: 1

Today, most design engineers don't pay much attention to variation. It's generally considered to be a manufacturing problem. Even within the fab, various job functions are segmented enough that variation in one part of the process, such as the photomask shop, doesn't necessarily come to the attention of the people doing deposition and etch or those polishing the wafers. But increasingly, ... » read more

Will AI Drive Scaling Forward?

By Ed Sperling - 17 Dec, 2018 - Comments: 0

The almost ubiquitous rollout of AI and its offshoots—machine learning, deep learning, neural nets of all types—will require significantly more processing power as the amount of data that needs to be processed continues to grow by orders of magnitude. What isn't clear yet is how that will affect semiconductor manufacturing or how quickly that might happen. AI is more than the latest buz... » read more

2 Big Shifts, Lots Of Questions

By Ed Sperling - 15 Nov, 2018 - Comments: 0

The proliferation of AI everywhere, and ongoing efforts by big systems companies to develop their own chips, could have a profound effect on semiconductor manufacturing for years to come. AI is a multi-faceted topic, but what makes this particularly interesting from a semiconductor standpoint is the architecture of AI-specific chips. So far, most of these chips have been developed for data c... » read more

EUV’s Uncertain Future

By Ed Sperling - 18 Oct, 2018 - Comments: 8

The ground appears to be solidifying under EUV. Intel announced this week it is reducing its stake in ASML to less than 3%, the second such move in a year. Apparently ASML no longer needs outside help. According to the company's earnings report, ASML turned in net sales of €2.776 billion, a slight increase over the €2.447 billion (GAAP) the company reported in Q3 and way up over the €... » read more

The Big Blur

By Ed Sperling - 20 Sep, 2018 - Comments: 0

Chip companies, research houses, foundries—and more recently large systems companies—have been developing alternative technologies to continue scaling power and performance. It's still not obvious which of those will win, let alone survive, or what they will do to the economics of developing chips. For more than five decades, the biggest concern was scaling devices in order to save money... » read more
