Week In Review: Auto, Security, Pervasive Computing


Hyundai, Samsung Catalyst Fund, and others invested a combined $100 million in Canada-based Tenstorrent to accelerate the design and development of AI chiplets and machine-learning software and allow the integration of AI into future Hyundai, Kia, and Genesis vehicles, plus other future mobilities such as robotics and advanced air mobility (AAM). The National Highway Traffic Safety Administr... » read more

Week In Review: Semiconductor Manufacturing, Test


China’s restrictions on the export gallium and germanium took effect this week. Any Chinese company exporting gallium or germanium that could be used in military and civil applications (dual-use) must obtain a license from China’s Ministry of Commerce. China produces 60% of the worldwide supply of germanium and 80% of the world’s gallium, both of which have to be processed from other mate... » read more

Rethinking Engineering Education In The U.S.


The CHIPS Act, as well as the ongoing need for talent, is causing both industry and academia in America to rethink engineering education, resulting in new approaches and stronger partnerships. As an example, Arizona State University (ASU) now has a Secure, Trusted, and Assured Microelectronics Center (STAM). The center offers an interdisciplinary approach to learning secure and trusted semic... » read more

Week In Review: Manufacturing, Test


Global semiconductor sales decreased 5.2% month-to-month in January, according to a new report by the Semiconductor Industry Association (SIA). For the year, worldwide chip sales are down 18.5%, with the largest drop in sales by China at 31.6%, followed by the Asia Pacific region at 19.5%, and the Americas at 12.4%. Despite the contraction, companies are increasing investments in manufacturi... » read more

Managing Thermal-Induced Stress In Chips


At advanced nodes and in the most advanced packages, physics is no one's friend. Escalating density, smaller features, and thinner dies make it more difficult to dissipate heat, and they increase mechanical stress. On the flip side, thinner dielectrics and tighter spaces make it more difficult to insulate and protect against that heat, and in conjunction with those smaller features and higher d... » read more

Bump Reliability is Challenged By Latent Defects


Thermal stress is a well-known problem in advanced packaging, along with the challenges of mechanical stress. Both are exacerbated by heterogenous integration, which often requires mingling materials with incompatible coefficients of thermal expansion (CTE). Effects are already showing up and will likely only get worse as package densities increase beyond 1,000 bumps per chip. “You comb... » read more

Expanding Advanced Packaging Production In The U.S.


The United States is taking the first steps toward bringing larger-scale IC packaging production capabilities back to the U.S. as supply chain concerns and trade tensions grow. The U.S. is among the leaders in developing packages, especially new and advanced forms of the technology that promise to shake up the semiconductor landscape. And while the U.S. has several packaging vendors, North A... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs IBM has unveiled what the company says is the world’s first 2nm chip. The device is based on a next-generation transistor architecture called a nanosheet FET. The nanosheet FET is an evolutionary step from finFETs, which is today’s state-of-the-art transistor technology. Targeted for 2024, IBM’s 2nm chip features a novel multi-Vt scheme, a 12nm gate length, and a n... » read more

The Week in Review: IoT


Finance Vectra raised $36 million in Series D funding led by Atlantic Bridge Capital. The Ireland Strategic Investment Fund and Nissho Electronics also participated in this funding round along with returning investors Khosla Ventures, Accel Partners, IA Ventures, AME Cloud Ventures, DAG Ventures, and Wipro Ventures, bringing Vectra’s total funding to date to $123 million. Vectra will use the... » read more

Power/Performance Bits: Feb. 9


Molybdenum disulfide memristors Researchers at Michigan Technological University constructed an ideal memristor based on molybdenum disulfide nanosheets. "Different from an electrical resistor that has a fixed resistance, a memristor possesses a voltage-dependent resistance," said Yun Hang Hu, professor of materials science and engineering at MTU, adding that a material's electric propert... » read more
