Monitoring Performance From Inside A Chip
By Ed Sperling - 01 Jun, 2021 - Comments: 0

Deep data, which is generated inside the chip rather than externally, is becoming more critical at each new process node and in advanced packages. Uzi Baruch, chief strategy officer at proteanTecs, talks with Semiconductor Engineering about using that data to identify potential problems before they result in failures in the field, and why it's essential to monitor these devices throughout their... » read more

Testing Analog Circuits Becoming More Difficult
By Susan Rambo - 11 May, 2021 - Comments: 1

Foundries and packaging houses are wrestling how to control heat in the testing phase, particularly as devices continue to shrink and as thermally sensitive analog circuits are added into SoCs and advanced packages to support everything from RF to AI. The overriding problem is that heat can damage chips or devices under test. That's certainly true for digital chips developed at advanced node... » read more

Chasing Test Escapes In IC Manufacturing
By Anne Meixner - 11 May, 2021 - Comments: 0

The number of bad chips that slip through testing and end up in the field can be significantly reduced before those devices ever leave the fab, but the cost of developing the necessary tests and analyzing the data has sharply limited adoption. Determining an acceptable test escape metric for an IC is essential to improving the yield-to-quality ratio in chip manufacturing, but what exactly is... » read more

Developers Turn To Analog For Neural Nets
By Bryon Moyer - 06 May, 2021 - Comments: 1

Machine-learning (ML) solutions are proliferating across a wide variety of industries, but the overwhelming majority of the commercial implementations still rely on digital logic for their solution. With the exception of in-memory computing, analog solutions mostly have been restricted to universities and attempts at neuromorphic computing. However, that’s starting to change. “Everyon... » read more

Tapping Into Non-Volatile Logic
By Bryon Moyer - 21 Apr, 2021 - Comments: 0

Research is underway to develop a new type of logic device, called non-volatile logic (NVL), based on ferroelectric FETs. FeFETs have been a topic of high interest at recent industry conferences, but the overwhelming focus has been using them in memory arrays. The memory bit cell, however, is simply a transistor that can store a state. That can be leveraged in other applications. “Non-v... » read more

Next-Gen Design Challenges
By Ed Sperling - 20 Apr, 2021 - Comments: 0

As more heterogeneous chips and different types of circuitry are designed into one system, that all needs to be simulated, verified and validated before tape-out. Aveek Sarkar, vice president of engineering at Synopsys, talks with Semiconductor Engineering about the intersection of scale complexity and systemic complexity, the rising number of corners, and the reduced margin with which to buffe... » read more

Latest IC Forecast: Big Demand, Shortages
By Mark LaPedus - 15 Apr, 2021 - Comments: 1

Over the last year, the semiconductor industry has seen its share of highs, lows and uncertainties. In early 2020, the business looked bright, but the IC market dropped amid the Covid-19 pandemic outbreak. Throughout 2020 different countries implemented a number of measures to mitigate the outbreak, such as stay-at-home orders and business closures. Economic turmoil and job losses soon follo... » read more

Power/Performance Bits: Dec. 23
By Jesse Allen - 23 Dec, 2020 - Comments: 0

Detecting early damage in power electronics Researchers at Osaka University to detect early damage in power electronics. The team used acoustic emission analysis to monitor in real time the propagation of cracks in a silicon carbide Schottsky diode during power cycling tests. During the power cycling test, the researchers mimicked repeatedly turning the device on and off, to monitor the res... » read more
