Challenges For Achieving Automotive Grade 1/0 Reliability In FCBGA and fcCSP Packages


As the quantity, complexity, and functions of electronic devices in automobiles increase, understanding and characterizing package reliability is of significant concern and importance. The Automotive Electronics Council (AEC) Q-100 specification for Grade 1 and 0 reliability introduces unique challenges as thermal cycling (TC) and high temperature storage (HTS) requirements increase. Additional... » read more

Vehicle Electrification Driving Supply Chain Evolution


Dr. Ajay Sattu, Director, Automotive Product Marketing, Amkor Technology, Inc. If the recently concluded CES 2022 is any indication, the automotive industry is yet again in the cross hairs of both consumers and industry experts alike. Whether it’s the new electric vehicle (EV) model introductions, color changing technologies, or concept cars, automotive companies are slowly transforming th... » read more

Wirebond IC Substrates: Challenges Ahead


Substrate suppliers are slashing capacity allocated to wirebond IC substrates. We hear about "limited tenting capacity," "no support for EBS designs," and requests for "conversion to etchback" designs. What does all this mean? Let's start with "Line" and "Space." "Line" is the width of a trace on a substrate and "Space" is the distance between the two traces. For wirebond packages such a... » read more

Chiplets Enter The Supercomputer Race


Several entities from various nations are racing each other to deliver and deploy chiplet-based exascale supercomputers, a new class of systems that are 1,000x faster than today’s supercomputers. The latest exascale supercomputer CPU and GPU designs mix and match complex dies in advanced packages, adding a new level of flexibility and customization for supercomputers. For years, various na... » read more

Technology Advances, Shortages Seen For Wire Bonders


A surge in demand for IC packages is causing long lead times for wire bonders, which are used to assemble three-fourths of the world’s packages. The wire bonder market doubled last year, alongside advanced packaging’s rise. Wirebonding is an older technology that typically flies under the radar. Still, packaging houses have multitudes of these key tools that help assemble many — but no... » read more

Chip-Last HDFO (High-Density Fan-Out) Interposer-PoP


Interposer Package-on-Package (PoP) technology was developed and has been in very high-volume production over the last several years for high-end mobile application processors (APs). This is due to its advantages of good package design flexibility, controllable package warpage at room temperature (25°C) and high temperature (260°C), reduced assembly manufacturing cycle time and chip-last asse... » read more

Next-Gen 3D Chip/Packaging Race Begins


The first wave of chips is hitting the market using a technology called hybrid bonding, setting the stage for a new and competitive era of 3D-based chip products and advanced packages. AMD is the first vendor to unveil chips using copper hybrid bonding, an advanced die-stacking technology that enables next-generation 3D-like devices and packages. Hybrid bonding stacks and connects chips usin... » read more

Future Challenges For Advanced Packaging


Michael Kelly, vice president of advanced packaging development and integration at Amkor, sat down with Semiconductor Engineering to talk about advanced packaging and the challenges with the technology. What follows are excerpts of that discussion. SE: We’re in the midst of a huge semiconductor demand cycle. What’s driving that? Kelly: If you take a step back, our industry has always ... » read more

Metal Thermal Interface Material For The Next Generation FCBGA


Thermal interface materials (TIMs) have been widely adopted for improved thermal dissipation in flip chip ball grid array (FCBGA), flip chip lidded ball grid array (FCLGA) and flip chip pin grid array (FCPGA) packaging. As the next generation devices' requirements for power get even higher, enhanced thermal performance at the package level is increasingly important. A typical TIM applies a poly... » read more

Achieving Success In Automotive Leadframe Packages


The growth of semiconductor content in automotive applications has been accelerating. This growth drives all families of semiconductor packaging in all regions. The growth is happening in the latest advanced, laminate-based packages using flip chip interconnect as well as the venerable leadframe packages using wirebond interconnect. The automotive market consumes micro-electromechanical systems... » read more
