Innovation And Collaboration In Power Module Packaging: A Thermal Perspective


Power modules are the foundation of modern electrical systems, especially within electric vehicles (xEVs), industrial motor applications, and renewable energy solutions such as wind and solar power. As the demand for more power in smaller and lighter systems grows, managing heat dissipation has become a major challenge, as the thermal energy from high current flows can lead to reliability issue... » read more

Fine-Line RDL Structure Analysis of Fan-Out Chip-on-Substrate Platform


Abstract: "The demand for high bandwidth memory (HBM) has driven the need for advanced packaging solutions, particularly those involving fan-out layers to interconnect wafers within packages. To meet the high-bandwidth requirements of the Fan-Out Chip-on-Substrate (FOCoS) technology platform, additional layers are required. However, as the number of fanout layers increases, significant chall... » read more

Backside Power Delivery Nears Production


Backside power delivery is being called a game changer — a breakthrough technology and the next great enabler in CMOS scaling. It promises significant PPA advances, including faster switching, lower voltage droop, and reduced power supply noise. And it is poised to deliver these benefits below the 2nm node, despite a substantial disruption in front-end processes from lithography pattern di... » read more

Packaging With Fewer People And Better Results


Advanced packaging has evolved far beyond the simple stacking of dies and connecting of interposers. Once a passive conduit between silicon and the outside world, it has become an active component of overall device performance. In today’s multi-die assemblies, the assembly and packaging lines are expected to maintain signal integrity at multi-gigahertz frequencies, manage heat in verticall... » read more

Advanced Atomistic Simulation Techniques For Atomic Layer Etching


Continuous downscaling of the critical dimensions in semiconductor devices is the cornerstone of technological revolution. As the technology nodes keep shrinking, innovations in fabrication technologies are needed to continue the trend. We have arrived at the age where atomic level precision in the fabrication of semiconductor devices is needed to keep improving PPA. Thus, advanced film fabrica... » read more

Three Ways Curvy ILT Together With PLDC Improves Wafer Uniformity


This is the second blog in a three-part series on pixel-level dose correction (PLDC). The first installment was “Improving Uniformity and Linearity for All Masks” from January 29, 2025. PLDC: A new solution for improving mask and wafer uniformity Improving mask uniformity is the easiest, cheapest way to improve wafer uniformity. Uniformity is a measure of how similarly the exact same feat... » 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
