The Opportunities And Challenges Of FOPLP Technology


Artificial intelligence (AI) has emerged as a major catalyst for innovation and advancement. The growing demand for AI computing power is driving heterogeneous integration toward larger packaging sizes, sparking increased interest in Fan-out Panel Level Package (FOPLP) technology. This article explores ASE’s practices and developments in this area, delving into the technical intricacies and e... » read more

Chiplet Design Considerations


Chiplets are a way to offer continuing increases in compute capacity and I/O bandwidth needs by splitting SoC functionality into smaller heterogeneous or homogeneous dies called chiplets and integrating these chiplets into a single system in package (SIP), where the total silicon content can exceed the reticle size of a single SoC. SIP includes traditional package substrates but also may includ... » read more

Reticle Stitching Bumps Up Silicon Interposer Costs


Advanced packaging often relies on silicon interposers to connect chiplets and other components inside a package. The problem is that interposers typically exceed the reticle limit, which adds both complexity and cost. An interposer is essential for 2.5D and 3.5D architectures. As device scaling runs out of steam, chipmakers are decomposing planar SoCs into chiplets and connecting them throu... » read more

On-Die And In-Package Interconnects: eBook


We live in the Information Age, but if information cannot get to where it's intended to go, it does no good. And the way information gets from here to there is through interconnects. This report focuses on different interconnect structures, such as lines, vias, buses, and networks-on-chip, and how they’re constructed. As always, we consider the design, test, reliability, and security impli... » read more

Physics Limits Interposer Line Lengths


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

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

Advanced Packaging Fundamentals for Semiconductor Engineers: eBook


Advanced packaging is inevitable. Large systems companies and processing vendors already are working with various types of highly engineered packaging. The rest of the semiconductor industry will follow at some point, whether they're designing their own packages, developing the tools, processes, materials, and methodologies to create them, or developing components that will be used inside of th... » read more

Big Changes Ahead For Interposers And Substrates


Interposers and substrates are undergoing a profound transformation from intermediaries to engineered platforms responsible for power distribution, thermal management, high-density interconnects, and signal integrity in the most advanced computing systems. This shift is being driven by AI, high-performance computing (HPC), and next-generation communications, where the need for heterogeneous ... » read more

AI And Semiconductor In Reciprocity


In today’s rapidly advancing technological era, AI has become a powerful catalyst for innovation and progress. Advanced semiconductor packaging plays a crucial role in supporting AI development, while AI applications create new semiconductor demands and drive the development of semiconductor technologies, with both complementing each other. Semiconductor packaging: The bridge between chip an... » read more

Assembly Design Rules Slowly Emerge


Process design kits (PDKs) play an essential in ensuring that silicon technology can proceed from one generation to the next in a manner that design tools can keep up with. No such infrastructure has been needed for packaging in the past, but that's beginning to change with advanced packages. Heterogeneous assemblies are still ramping up, but their benefits are attracting new designs. “Chi... » read more
