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

Week In Review: Manufacturing, Test


Packaging Amkor plans to build a packaging plant in Bac Ninh, Vietnam. The first phase of the new factory will focus on providing system-in-package (SiP) assembly and test services for customers. The investment for the first phase of the facility is estimated to be between $200 million and $250 million. “This is a strategic, long-term investment in geographical diversification and factory... » read more

Manufacturing Bits: Nov. 2


IRDS lithography roadmap The Journal of Micro/Nanopatterning, Materials, and Metrology (JM3) has published a paper that outlines the lithography roadmap and the various challenges for the next 15 years. The paper, called the "International Roadmap for Devices and Systems lithography roadmap," projects that extreme ultraviolet (EUV) lithography and a next-generation version will remain the m... » read more

Manufacturing Bits: Oct. 5


EUV lithography storage ring At the recent SPIE Photomask Technology + EUV Lithography conference, Japan’s High Energy Accelerator Research Organization (KEK) presented a paper on its latest efforts to develop a free-electron laser (FEL) storage ring source power unit for extreme ultraviolet (EUV) lithography. KEK has demonstrated a proof-of-concept EUV-FEL, which has been in R&D. EUV-FEL... » read more
