Meeting High-Frequency And Power Density Challenges With Flip Chip MLF Packaging


The relentless march of semiconductor scaling continues to reshape the packaging landscape, driven by Moore’s Law and the demand for higher performance in increasingly compact form factors [1]. Over the past two decades transistor density has increased exponentially, with leading-edge processes now achieving densities exceeding 100 million transistors per square millimeter. Certain applica... » read more

Quantifying The Impact Of Gravity On Strip Warpage Across Assembly Stages


The mechanical behavior of electronic packages is an important consideration at each stage of the assembly process. Many packages are assembled in strip format, making strip warpage a critical challenge for manufacturability and yield. Accurate simulations for strip warpage are an effective tool to determine what factors cause large warpages and to explore solutions before assembly. In these si... » read more

Advanced Packaging Limits Come Into Focus


Key Takeaways: Packaging is now a performance variable. Substrate, bonding, and process sequence determine what can be built at scale. Warpage underlies most advanced packaging failures and gets harder to control as package sizes grow. Every proposed solution, such as glass, panel processing, and backside power, solves one problem while creating another. Moore's Law has shif... » read more

Redefining Backside Metallization: Low‑Temperature Solutions For HDFO And S‑SWIFT Designs


As chip performance and integration continue to advance, thermal dissipation control has become increasingly critical not only at the wafer fabrication level but also in the packaging industry. For artificial intelligence (AI) and high performance computing (HPC) applications, the industry is gradually shifting toward 2.5D integration. In response to the growing demand, High-Density Fan-Out (HD... » read more

Laser Arrays May Simplify Co-Packaged Optics


Key Takeaways Moving photonic ICs into the same package as silicon helps improve performance, but lasers remain outside. A new monolithic laser array allows hundreds of colors, each individually software-tunable New options are being turned into products, which could help commercialize CPO. The move to co-packaged optics (CPO) holds the promise of putting photonic ICs (PICs)... » read more

Chip Industry Week In Review


Geopolitics U.S. lawmakers are urging tighter export controls on advanced semiconductor manufacturing equipment (SME) to China, warning existing loopholes threaten national security. "China is working to build domestic SME by exploiting access to U.S. and allied subcomponents required to produce tools," states the letter, which also says better coordination with allies is essential. The U.S.... » read more

Investments came from both industry and government sources. Organizations worked together to solve current technology challenges, including soaring demand for AI chips and advanced memory, as well as complex applic... » read more

Unlocking Next-Gen Thermal Management: Why Indium-Based Metal TIMs Are Game-Changers


As electronic devices become more powerful and compact, thermal management has become one of the most critical challenges in advanced electronic packaging. High-performance processors used in AI computing, data centers, and 5G/6G infrastructure generate significant heat, and failure to dissipate effectively can lead to reduced performance, reliability issues, and even catastrophic component fai... » read more

Reliability Risks Shift To The Materials Stack


The semiconductor industry’s push into 3D integration and large-format substrates has fundamentally changed the role of materials in packaging. What were once structural supports and electrical insulators have become critical performance limiters. Modern packages contain far more polymers, adhesives, advanced dielectrics, thermal materials, and composite laminates than previous generations... » read more

What’s Next for 2.5D Packaging?


Interposers and bridges, two of the key elements for interconnecting multiple chips and chiplets in an advanced package, are undergoing fundamental changes in how they're built and assembled. Interposers are becoming thicker and more complex, while bridges are being used to reduce the assembled cost. Both efforts are facing new challenges. Interposers are effectively platforms on which mu... » read more
