Front-End Technologies Are The New Back-End Tools: Using Picosecond Ultrasonics Technology For AI Packages, Part 1


If you are a part of the semiconductor industry or simply someone interested in the field, you have likely heard what has become a common refrain: the back-end of the process is becoming more like the front-end of the process. In other words, the technologies that were once exclusively deployed in the first part of the process are being used to meet the increasingly stringent requirements of ad... » read more

Addressing Stress In Heterogeneous 3D-IC Designs


The benefits of 3D IC architectures are well-documented – smaller footprints, lower power, and increased performance. However, the move to heterogeneous 3D designs also introduces a host of new challenges that must be carefully navigated. As chip designers integrate multiple dies and technologies into a single 3D package, the interactions between the chip and package become increasingly co... » 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

Chip Complexity Drives Innovation In Automated Test Equipment


Innovations in semiconductor technology—such as advancements in AI high-performance computing (HPC), Angstrom-scale silicon process nodes, silicon photonics, and automotive xEV wideband gap power transistor applications—require automated test equipment (ATE) to evolve at an unprecedented rate. As chip complexity grows, the challenges in design, manufacturing, and test multiply. It is a comp... » read more

Research Bits: April 22


PIC heterogeneous integration Researchers from Hewlett Packard Labs, Indian Institutes of Technology Madras, Microsoft Research, and University of Michigan built an AI acceleration platform based on heterogeneously integrated photonic ICs. The PIC combines silicon photonics along with III-V compound semiconductors that functionally integrate lasers and optical amplifiers to reduce optical l... » read more

Advanced Packaging Fundamentals for Semiconductor Engineers


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

Study Of Multi-Die And Multi-Technology Floorplanning (Texas A&M, Duke)


A new technical paper titled "PPAC Driven Multi-die and Multi-technology Floorplanning" was published by Texas A&M University and Duke University. Abstract "In heterogeneous integration, where different dies may utilize distinct technologies, floorplanning across multiple dies inherently requires simultaneous technology selection. This work presents the first systematic study of multi-die ... » read more

What Exactly Are Chiplets And Heterogeneous Integration?


The terms “chiplet” and “heterogeneous integration” fill news pages, conference papers, and marketing presentations, and for the most part engineers understand what they're reading. But speakers sometimes stumble during a presentation trying to figure out whether a particular die qualifies as a chiplet, and heterogeneous integration comes in different guises for different people. Both t... » read more
