New Package Solutions for Automotive Optical Sensors


This article introduces the development of a new optical ball grid array (OBGA) packaging platform designed for automotive applications, with a focus on platform development and compliance with the Automotive Electronics Council (AEC) AEC-Q100 Grade 2 reliability standard. The proposed packaging solution extends beyond traditional cavity OBGA packages, which have been primarily utilized for mic... » 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

Three-Way Race To 3D-ICs


Intel Foundry, TSMC, and Samsung Foundry are scrambling to deliver all the foundational components of full 3D-ICs, which collectively will deliver orders of magnitude improvements in performance with minimal power sometime within the next few years. Much attention has been focused on process node advances, but a successful 3D-IC implementation is much more complex and comprehensive than just... » read more

Co-Design Optimization For PI/SI When Considering Thermal Performance


When applications become more complex, higher data rates or high frequencies are required. However, with increasing functions, more power dissipation will be generated. Furthermore, temperature is proportional to power dissipation, so electrical performance will also depend on thermal conditions. To determine how temperature impacts power integrity/signal integrity (PI/SI), electrical simulatio... » read more

The Other Side Of The Wafer: Transistor Channel Stress In Backside Power Delivery Networks


As transistor scaling has moved to the angstrom era (18A, 14A, etc.), the issues of interconnect resistance (IR), IR drop, and power loss are becoming more severe. Traditionally, signal lines and power lines are fabricated on the same side of the wafer as the active device. But fabricating everything on one side of the wafer can create a shortage of space and resources at the interconnect la... » read more

TCAD For GPUs And GPUs For TCAD


It is well known that many steps in chip development become exponentially harder as feature sizes shrink and instance counts balloon. Billions of transistors are now commonplace, and wafer-scale devices with trillions are on the horizon. Such massive chips put pressure on every electronic design automation (EDA) tool in the development flow, from front-end architectural modeling to signoff and ... » read more

Can Chiplets Serve Cost-Conscious Apps?


Chiplets are emerging as a significant new phase in the evolution of the semiconductor market, providing a way to continue scaling performance well beyond the size limitations of a reticle. But that improvement comes with a high price tag and a lot more complexity, which so far has limited adoption. One of the main reasons for the cost increase is the need for advanced packaging when employi... » read more

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
