More Accurate And Detailed Analysis of Semiconductor Defects In SEM Images Using SEMI-PointRend


A technical paper titled "SEMI-PointRend: Improved Semiconductor Wafer Defect Classification and Segmentation as Rendering" was published (preprint) by researchers at imec, University of Ulsan, and KU Leuven. Abstract: "In this study, we applied the PointRend (Point-based Rendering) method to semiconductor defect segmentation. PointRend is an iterative segmentation algorithm inspired by ima... » read more

IEDM: Backside Power Delivery


One part of the short course that I attended at IEDM in December was about backside power delivery networks. It was presented by Gaspard Hiblot of imec and titled "Process Architectures Changes to Improve Power Delivery." The presentation is co-credited with Geert Hellings and Julien Ryckaert. I should preface this post with the fact that this presentation was 80 slides long and so I will only... » read more

Standards: The Next Step For Silicon Photonics


Testing silicon photonics is becoming more critical and more complicated as the technology is used in new applications ranging from medicine to cryptography, lidar, and quantum computing, but how to do that in a way that is both consistent and predictable is still unresolved. For the past three decades, photonics largely has been an enabler for high-speed communications, a lucrative market t... » 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

Formal Processor Model Providing Secure Speculation For The Constant-Time Policy


A technical paper titled "ProSpeCT: Provably Secure Speculation for the Constant-Time Policy (Extended version)" was published by researchers at imec-DistriNet at KU Leuven, CEA, List, Université Paris Saclay and INRIA. Abstract: "We propose ProSpeCT, a generic formal processor model providing provably secure speculation for the constant-time policy. For constant-time programs under a no... » read more

Week In Review: Auto, Security, Pervasive Computing


Automotive Ambarella will use Samsung's 5nm process technology for its new CV3-AD685 automotive AI central domain controller, bringing "new levels of AI acceleration, system integration and power efficiency to ADAS and L2+ through L4 autonomous vehicles.” Renesas introduced four technologies for automotive communication gateway SoCs: (1) an architecture that dynamically changes... » read more

Research Bits: Feb. 21


High-quality ‘chirps’ for automotive, industrial mmWave radar Imec demonstrated a low-power phase-locked loop (PLL) that generates high-quality frequency-modulated continuous-wave (FMCW) signals for mmWave radar, which can be used in short-range automotive and industrial radar applications. The FMCW radars popular in healthcare, automotive, and industrial send out sinusoidal waves that get... » 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

Devices And Transistors For The Next 75 Years


The 75th anniversary of the invention of the transistor sparked a lively panel discussion at IEDM, spurring debate about the future of CMOS, the role of III-V and 2D materials in future transistors, and what will be the next great memory architecture.[1] Industry veterans from the memory, logic, and research communities see high-NA EUV production, NAND flash with 1,000 layers, and hybrid bon... » read more

Disaggregating And Extending Operating Systems


The push toward disaggregation and customization in hardware is starting to be mirrored on the software side, where operating systems are becoming smaller and more targeted, supplemented with additional software that can be optimized for different functions. There are two main causes for this shift. The first is rising demand for highly optimized and increasingly heterogeneous designs, which... » read more
