Auto Industry Relationships Re-Form, But Differently


The automotive industry is in the midst of rapid change on many fronts. OEMs are exploring new functions and features to add to their vehicles, including chiplets, electrification, autonomous features, as well as new vehicle architectures that will determine how vehicles are going to be designed from the foundation up. But all of this is dependent on the relationships between all of the ecosyst... » read more

Journey From Cell-Aware To Device-Aware Testing Begins


Early results of using device-aware testing on alternative memories show expanded test coverage, but this is just the start. Once the semiconductor industry realized that it was suffering from device failures even when test programs achieved 100% fault coverage, it went about addressing this disconnect between the way defects manifest themselves inside devices and the commonly used fault mod... » read more

Week In Review: Semiconductor Manufacturing, Test


The Cyberspace Administration of China recommended a ban of Micron chips for critical information infrastructure (CII), alleging serious network security risks. According to a statement from China's Network Security Review Office, "Micron's products have relatively serious potential network security issues, which pose a major security risk to [China's] critical information infrastructure supply... » read more

Automotive Relationships Shifting With Chiplets


The automotive industry is in the midst of a tremendous and rapid change on many fronts. OEMs are exploring new functions and features to add to their vehicles, including chiplets, electrification, autonomous features, as well as new vehicle architectures that will determine how vehicles are going to be designed from the foundation up. All of this is dependent on the relationships between all o... » read more

Week In Review: Semiconductor Manufacturing, Test


TECHCET is forecasting semiconductor precursor revenues, both for high-ƙ metal dielectrics and low-ƙ dielectrics, will increase in the second half of 2023, rebounding from the current zero percent growth rate. Wafer start volumes are expected to rebound in 2024 with expansions in 2nm and 3nm logic devices. SEMI also predicts the global slump in semiconductor sales will end this quarter, gi... » read more

Etch Processes Push Toward Higher Selectivity, Cost Control


Plasma etching is perhaps the most essential process in semiconductor manufacturing, and possibly the most complex of all fab operations next to photolithography. Nearly half of all fab steps rely on a plasma, an energetic ionized gas, to do their work. Despite ever-shrinking transistor and memory cells, engineers continue to deliver reliable etch processes. “To sustainably create chips... » read more

Managing Yield With EUV Lithography And Stochastics


Identifying issues that actually affect yield is becoming more critical and more difficult at advanced nodes, but there is progress. Although they are closely related, yield management and process control are not the same. Yield management seeks to maximize the number of functioning devices at the end of the line. Process control focuses on keeping each individual device layer within its des... » read more

Week In Review: Semiconductor Manufacturing, Test


The global sales slump in semiconductors but may be stabilizing, according to a new report from the Semiconductor Industry Association (SIA). Worldwide sales of semiconductors fell 8.7% in Q1 2023 compared to the Q4 2022, and dropped 21.3% compared to the Q1 2022. Sales for the month of March 2023 increased 0.3% compared to February 2023. Meanwhile, SEMI reports worldwide silicon wafer shipment... » read more

Assist Layers: The Unsung Heroes of EUV Lithography


Most discussions of advanced lithography focus on three elements — the exposure system, photomasks, and photoresists — but that's only part of the challenge. Successfully transferring a pattern from the photomask to a physical structure on the wafer also depends on a variety of films working together, including the underlayers, the developers, and a variety of surface treatments. In fact... » read more

Nanoimprint Finally Finds Its Footing


Nanoimprint lithography, which for decades has trailed behind traditional optical lithography, is emerging as the technology of choice for the rapidly growing photonics and biotech chips markets. First introduced in the mid-1990s, nanoimprint lithography (NIL) has consistently been touted as a lower-cost alternative to traditional optical lithography. Even today, NIL potentially is capable o... » read more
