Chip Industry Week In Review


By Jesse Allen, Karen Heyman, and Liz Allan AMD took the covers off new AI accelerators for training and inferencing of large language model and high-performance computing workloads. In its announcement, AMD focused heavily on performance leadership in the commercial AI processor space through a combination of architectural changes, better software efficiency, along with some improvements in... » read more

Week In Review: Semiconductor Manufacturing, Test


Starting in 2025, SEMICON West will move to Phoenix for a five-year annual rotation. And in 2024, it will shift dates from July to October. This year’s conference will still take place July 11 to 13 at the Moscone Center. Phoenix will first host SEMICON West on October 7-9, 2025. Thereafter, it will be held at the Moscone Center in San Francisco on the alternating years and over the long term... » read more

Week In Review: Semiconductor Manufacturing, Test


Nikkei Asia reports the U.S. is urging allies, including Japan, to restrict exports of advanced semiconductors and related technology to China. The U.S. holds 12% of the global semiconductor market, Japan has a 15% share, while Taiwan and South Korea each have about a 20% share. Some U.S. companies have called for other countries to adopt U.S.-style export curbs, arguing it is unfair for only A... » read more

Neuromorphic photonic circuit modeling in Verilog-A


Abstract "One of the significant challenges in neuromorphic photonic architectures is the lack of good tools to simulate large-scale photonic integrated circuits. It is crucial to perform simulations on a single platform to capture the circuit’s behavior in the presence of both optical and electrical components. Here, we adopted a Verilog-A based approach to model neuromorphic photonic cir... » read more

Week In Review: Manufacturing, Test


Chipmakers TSMC has introduced another version of its 4nm process technology. The process, called N4X, is tailored for high-performance computing products. Recently, TSMC introduced another 4nm process, called N4P, which is an enhanced version of its 5nm technology. N4X is also an enhanced version of its 5nm technology. N4X, however, offers a performance boost of up to 15% over TSMC’s N5 pro... » read more

Will Open-Source EDA Work?


Open-source EDA is back on the semiconductor industry's agenda, spurred by growing interest in open-source hardware. But whether the industry embraces the idea with enough enthusiasm to make it successful is not clear yet. One of the key sponsors of this effort is the U.S. Defense Advanced Research Projects Agency (DARPA), which is spearheading a number of programs to lower the cost of chip ... » read more

System Bits: May 2


AI systems echo human prejudices One of the concerns about the of future artificial intelligence systems includes the perception that these machine-based systems are coldly logical and objectively rational, however, this may not be the case. In fact, in a new study by Princeton University researchers has shown how machines can be reflections of their creators in potentially problematic ways. ... » read more

System Bits: Aug. 25


Quantum computer building block In a finding that could ultimately be used to produce key components of quantum computers in the future, a team of researchers led by MIT have analyzed an exotic kind of magnetic behavior, driven by the mere proximity of two materials, using a technique called spin-polarized neutron reflectometry. This discovery could also be used to probe a variety of exotic... » read more

System Bits: Dec. 30


3D printing merges plastics, active electronics Princeton researchers have embedded tiny light-emitting diodes into a standard contact lens, allowing the device to project beams of colored light as part of a project demonstrating 3-D printing techniques. And while the lens is not designed for actual use — it requires an external power supply — the device was created to demonstrate the a... » read more

Manufacturing Bits: June 17


PiezoFET debuts The University of Twente MESA+ Research Institute and SolMateS have put a new twist on the finFET. A piezoelectric stressor layer has been deposited around the finFET, thereby enabling what researchers call the PiezoFET. The PiezoFET could enable steep sub-threshold slope devices. In the lab, this device was also able to reduce the leakage by a factor of five. [caption id... » read more
