Chip Industry Week In Review


Disruptions caused by the Iran conflict have taken about one third of the global helium supply off the market, an essential gas for semiconductor manufacturing, reports the World Economic Forum. Other potential impacts for the chip industry include bromine and other chemical shortages, logistical disruptions, and higher energy prices incurred by fabs in Asia. Top Deals IBM and Lam R... » read more

Charting The Frontiers Of Photomask Technology And Extreme Ultraviolet Lithography


The enormous computing demands of AI and high-performance computing (HPC) applications are putting intense pressure on every aspect of chip development. Challenges arise during architecture, design, and verification, persist through the manufacturing process, and extend to post-silicon lifecycle management as chips are deployed in the field. Lithography, the fabrication step of shining light... » read more

Takeaways From The 2024 SPIE Photomask Technology + EUV Conference


In the autumn, I had the opportunity to attend the 2024 SPIE Photomask Technology and EUV Lithography conferences, collectively referred to as PUV or sometimes BACUS, the latter a reference to the event’s early association with the BACUS organization. This is a key annual event that brings together experts and professionals in photomask technology and EUV lithography. This year’s conference... » read more

Make The Impossible Possible: Use Variable-Shaped Beam Mask Writers And Curvilinear Full-Chip Inverse Lithography Technology For 193i Contacts/Vias With Mask-Wafer Co-Optimization


Abstract: "Full-chip curvilinear inverse lithography technology (ILT) requires mask writers to write full reticle curvilinear mask patterns in a reasonable write time. We jointly study and present the benefits of a full-chip, curvilinear, stitchless ILT with mask-wafer co-optimization (MWCO) for variable-shaped beam (VSB) mask writers and validate its benefits on mask and wafer at Micron Tec... » 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

Week In Review: Semiconductor Manufacturing, Test


Semiconductor Research Corporation (SRC) released an interim roadmap for Microelectronic and Advanced Packaging Technologies (MPAT) that targets 10- to 15-year goals for 3D integration and multi-chiplet packaging. The roadmap is open for comments. Participants in the MPAT include AMD, IBM, Intel, Texas Instruments, Purdue University, SUNY Binghamton and the Georgia Institute of Technology. It i... » read more

Week In Review: Auto, Security, Pervasive Computing


The U.S. Department of Defense updated the directive that governs the development and fielding of autonomous and semi-autonomous weapon systems. The revisions include an expanded focus on artificial intelligence, and reference to recently-established organizations like the DoD’s Chief Digital and Artificial Intelligence Office. NIST released a new guidance document aimed at helping organi... » read more

Week In Review: Manufacturing, Test


It's earnings season, and despite widespread reports of capacity issues and shortages, the chip industry turned in relatively solid results across the board. Intel exceeded January guidance for Q1, reporting first-quarter GAAP revenue of $18.4 billion, a 7% year-over-year decrease, and a 1% decrease year-over-year on non-GAAP basis. Record revenue was achieved in the Network and Edge Group, ... » read more

Auto Chipmakers Dig Down To 10ppb


How do engineers deliver 10 defective parts per billion (Dppb) to auto makers if they only screen 1 million parts per year? Answer: By comprehending failure mechanisms and proactively screening for them. Modern automobiles contain nearly 1,000 ICs that must perform over the vehicle’s life (15 years). This drives quality expectations ever higher. While 10 Dppm used to be a solid benchmark, ... » read more

Chemistry Working For Lithography: The Marangoni-Effect-Based Single Layer For Enhanced Planarization


In the field of semiconductor manufacturing, there is still a continuous search for techniques to improve the Critical Dimension Uniformity (CDU) across the wafer. CDU improvement and general defectiveness reduction increase the industrial yield and guarantee high reliability standards. In the KrF Dual-Damascene module integration, at a lithographic level, deep trench planarization is mandatory... » read more
