RETBLEED: New Spectre-BTI Attack (ETH Zurich)


New Spectre-BTI attack that "leaks arbitrary kernel memory." It's detailed in this research paper titled “RETBLEED: Arbitrary Speculative Code Execution with Return Instructions” from researchers at ETH Zürich. Mitigations are available. Abstract "Modern operating systems rely on software defenses against hardware attacks. These defenses are, however, as good as the assumptions they m... » read more

Week In Review, Manufacturing, Test


The U.S. is attempting to restrict sales of ASML’s deep ultra-violet (DUV) litho systems to China, according to a report from Bloomberg. The U.S. has been working to limit China's access to advanced technology for some time, and it has already limited sales of extreme ultra-violet (EUV), which is used to develop chips at the most advanced process nodes. DUV, in contrast, is used for older-nod... » read more

Security Risks Widen With Commercial Chiplets


The commercialization of chiplets is expected to increase the number and breadth of attack surfaces in electronic systems, making it harder to keep track of all the hardened IP jammed into a package and to verify its authenticity and robustness against hackers. Until now this has been largely a non-issue, because the only companies using chiplets today — AMD, Intel, and Marvell — interna... » read more

What Formula 1 Racing Says About Auto’s High-Tech Future


To learn about the future of the auto industry, you can interview analysts and experts, peruse scientific publications, and attend various conferences. Or you can watch multi-million dollar race cars hurtle around a track at speeds of upwards of 220 miles per hour. Welcome to Formula 1, the international auto racing sport with a cumulative TV audience of 1.55 billion people. The budgets are ... » read more

Week In Review, Manufacturing, Test


Samsung announced initial production of its 3nm process node, which uses a gate-all-around (nanosheet) transistor structure that the company calls Multi-Bridge-Channel FET (MBCFET). The first-generation 3nm process can reduce power consumption by up to 45% compared with a 5nm process, as well as improve performance by 23% and reduce area by 16%, according to the company. The second-generation 3... » read more

EDA Gaps At The Leading Edge


Semiconductor Engineering sat down to discuss why new approaches are required for heterogeneous designs, with Bari Biswas, senior vice president for the Silicon Realization Group at Synopsys; John Lee, general manager and vice president of the Ansys Semiconductor business unit; Michael Jackson, corporate vice president for R&D at Cadence; Prashant Varshney, head of product for Microsoft Azu... » read more

Week In Review: Manufacturing, Test


Notes from the fabs Intel warned the “scope and pace" of the Ohio fab buildout could be impacted due to U.S. Congress’ inaction on funding the $52 billion CHIPS Act. The facility was announced in January with an initial phase investment of more than $20 billion with a larger expansion up to $100 billion over the next decade. The initial phase is not expected to be impacted, other than a de... » read more

Why Hardware-Dependent Software Is So Critical


Hardware and software are two sides of the same coin, but they often live in different worlds. In the past, hardware and software rarely were designed together, and many companies and products failed because the total solution was unable to deliver. The big question is whether the industry has learned anything since then. At the very least, there is widespread recognition that hardware-depen... » read more
