Variable Bias Completes The PLDC Model And Offers Superior MPC Results

By Aki Fujimura - 19 Jun, 2025 - Comments: 0

This is the third in a three-blog series on PLDC. The first installment was “Improving Uniformity and Linearity for All Masks,” from January 29, 2025. The second blog was “Three Ways Curvy ILT Together with PLDC Improves Wafer Uniformity,” from April 18, 2025. In 2024, the eBeam Initiative Luminaries Survey found that the number one concern in adoption of curvilinear mask features wa... » read more

Improving Fab Engineering Efficiency With Autonomous Data Analytics

By Peter Barar - 19 Jun, 2025 - Comments: 0

During my earlier career as a process integration engineer, one of my primary responsibilities was to find yield enhancement opportunities by investigating underlying relationships between bin failures and process parameters within the fab. While performing this analysis, there were many impediments to identifying relationships among different data types: sort maps, electrical test maps, parame... » read more

Physics Limits Interposer Line Lengths

By Bryon Moyer - 19 Jun, 2025 - Comments: 1

Electrical interposers provide a convenient surface for mounting multiple chips within a single package, but even though interposer lines theoretically can be routed anywhere, insertion losses limit their practical length. Lines on interposers — and on silicon interposers in particular — can be exceedingly narrow. Having a small cross-section makes such lines resistive, degrading signals... » read more

How An Environmental Sustainability Community Fostered Employee-Driven Innovation

By Lam Research - 19 Jun, 2025 - Comments: 0

Co-written by S. Sinan Erzurumlu (Babson College), Wojciech T. Osowiecki (Lam Research) and Victor P. Seidel (Babson College). Firms are increasingly promoting innovations that advance environmental sustainability across all aspects of their business, but this can be challenging in global, complex, technology-focused organizations. Much research has focused on top-down strategic initiatives;... » read more

Critical Minerals Due Diligence And The Semiconductor Supply Chain

By Kimberly Harrison - 19 Jun, 2025 - Comments: 0

“Critical minerals our world needs for electric vehicles and semiconductors can be found here. Clean energy we need to power artificial intelligence data centers and economic growth can be built here.”[1] This statement was made by former US President Joseph Biden during his visit to Angola in December 2024 to support a US-funded railroad project called the Lobito Corridor. The railroad wou... » read more

Are Larger Reticle Sizes On The Horizon?

By Katherine Derbyshire - 19 Jun, 2025 - Comments: 0

Making high-NA EUV lithography work will take a manufacturing-worthy approach to stitching together circuits or a wholesale change to larger masks. Circuit stitching between the exposure fields is challenging the design, yield and manufacturability of the high-NA (0.55) EUV transition. The alternative is a radical change from 6x6-inch to 6x11-inch masks that would eliminate stitching, but it... » read more

2024 Corporate Responsibility Report

By Amkor - 19 Jun, 2025 - Comments: 0

Amkor recognizes the need for transparent reporting, and we have been publishing annual reports to facilitate the disclosure of comparable, consistent, and reliable information about our initiatives and progress for our stakeholders. Last year, we verified our targets to achieve net-zero greenhouse gas emissions by 2050, including near-term targets, with the Science Based Targets initiative ... » read more

Thermoelectricity in Topological Flat-Band Compounds (TU Wien, et al.)

By Technical Paper Link - 18 Jun, 2025 - Comments: 0

A new technical paper titled "Topological Flat-Band-Driven Metallic Thermoelectricity" was published by researchers at TU Wien, Los Alamos National Lab, Flatiron Institute and others. Abstract "Materials where flattened electronic dispersions arise from destructive phase interference, rather than localized orbitals, have emerged as promising platforms for studying emergent quantum phenome... » read more
