Chip Industry Week In Review


Manufacturing ASE and WUS are jointly building a ~$1.1B advanced packaging hub in Kaohsiung, Taiwan, for fan-out chip-on-substrate (FOCoS) and flip-chip ball grid array (FC BGA) technologies. The new site is expected to be completed by September 2029. SpaceX filed documents for a “Terafab” semiconductor manufacturing and computing facility at Gibbons Creek Reservoir in Texas, with a... » read more

Panel-Level Packaging’s Second Wave Meets Engineering Reality


Key Takeaways Panel-level packaging is arriving not because the engineering is ready, but because wafer-level economics are breaking down. Glass improves the warpage and dimensional stability problems of organic substrates but introduces a different class of failure modes that require materials solutions, not process adjustments. The central challenges of panel-level processing are m... » read more

Chip Industry Week In Review


China's Hefei Lumiverse Technology reportedly has developed a desktop-sized High Harmonic Generation light source that generates wavelengths as small as 1nm. One customer already has used it to produce 14nm chips, which was the original target node for EUV, according to one report. As a point of comparison, TSMC and Samsung didn't start using EUV until the 7nm node, relying instead on immersion... » read more

The Rise Of Panel-Level Packaging


An insatiable demand for logic to memory integration for AI and high-performance computing is driving progress toward very large-format packages, which are expected to approach 10 times the maximum reticle size in the next few years. These assemblies are best developed using fan-out panel-level packaging, replacing today’s wafer carrier with a panel. Fan-out packaging enables substantially... » read more

Novel Assembly Approaches For 3D Device Stacks


The next big leap in semiconductor packaging will require a slew of new technologies, processes, and materials, but collectively they will enable orders of magnitude improvement in performance that will be essential for the AI age. Not all of these issues are fully solved but the recent Electronic Components Technology Conference (ECTC) provided a glimpse into the huge leaps in progress that... » read more

Advanced Packaging Depends On Materials And Co-Design


Multi-die assemblies offer significant opportunities to boost performance and reduce power, but these complex packages also introduce a number of new challenges, including die-to-RDL misalignment, evolving warpage profiles, and CTE mismatch. Heterogeneous integration — an umbrella term that covers many different applications and packaging requirements — holds the potential to combine com... » read more

3D Integration And Test Results From TSV-Processed Chips (CERN et al.)


A new technical paper titled "3D integration of pixel readout chips using Through-Silicon-Vias" was published by researchers at CERN, IZM Fraunhofer and University of Geneva. Abstract "Particle tracking and imaging detectors are becoming increasingly complex, driven by demands for densely integrated functionality and maximal sensitive area. These challenging requirements can be met using 3D... » read more

How Die Dimensions Challenge Assembly Processes


Multi-die assemblies are becoming more common and more complex due to technology advancements and market demands, but differing die dimensions are making this process increasingly challenging. To fully enable a multi-chiplet ecosystem, standardized component handling and interfaces are needed. The underlying concept is similar to LEGO blocks that simply snap together, yet it's nowhere near t... » read more

What Works Best For Chiplets


The semiconductor industry is preparing for the migration from proprietary chiplet-based systems to a more open chiplet ecosystem, in which chiplets fabricated by different companies of various technologies and device nodes can be integrated in a single package with acceptable yield. To make this work as expected, the chip industry will have to solve a variety of well-documented technical an... » read more
