CPO Will Dominate Scale-Up: Link Budgets For dB And $ Are Key


In the next five years, scale-up interconnects will transition from copper to optical interconnects — primarily co-packaged optics (CPO), with some near-packaged optics (NPO), and perhaps some vertical-cavitity-surface-emitting lasers (VCSELs). The demand for AI has become visibly real with Anthropic hitting a $47 billion annual run rate, followed closely by OpenAI and Google Gemini. Anthr... » read more

Glass Substrates Gain Momentum


As a package substrate, the benefits of glass are substantial. It's extremely flat with lower thermal expansion than organic substrates, which simplifies lithography. And that's just for starters. Warpage, a growing problem for multichip packages, is greatly reduced. Chips can be hybrid bonded to redistribution layer pads on glass. And relative to organic-core substrates, glass provides very... » read more

The Rise Of Panel-Level Packaging


An insatiable demand for logic to memory integration for AI and high-performance computing is driving progress toward very large-format packages, which are expected to approach 10 times the maximum reticle size in the next few years. These assemblies are best developed using fan-out panel-level packaging, replacing today’s wafer carrier with a panel. Fan-out packaging enables substantially... » read more

Novel Assembly Approaches For 3D Device Stacks


The next big leap in semiconductor packaging will require a slew of new technologies, processes, and materials, but collectively they will enable orders of magnitude improvement in performance that will be essential for the AI age. Not all of these issues are fully solved but the recent Electronic Components Technology Conference (ECTC) provided a glimpse into the huge leaps in progress that... » read more

On The Ground At ECTC 2025


Senior Executive Editor Laura Peters examines the the hot topics at last week's IEEE's Electronic Components and Technology Conference, including the impact of hardware-software integration on power consumption, co-packaged optics, hybrid bonding, and fan-out panel-level packaging. https://youtu.be/yBDKqrPQBl4   » read more

ECTC 2024 Session Readout: Advancement of Metrology


A Electronic Components and Technology Conference (ECTC) session report titled "2024 ECTC Special Session Report: Advancing Metrology for Next-Generation Microelectronics" was published by NIST, Binghamton University, and TechSearch International. Abstract: "Metrology plays a pivotal role in semiconductor research, manufacturing, packaging and assembly. It is critical to the success of this... » read more

Photonic Debond: Scalability And Advancements


Advanced packaging technology has continuously evolved over the past 10-20 years to become a major driving force in improving integrated circuit (IC) performance. This improvement in IC performance is assisted by the ability to place specialized components near each other for shorter interconnects in the IC packages. Temporary bond and debond (TB/DB) is an enabling technique for this work. TB/D... » read more

Piecing Together Chiplets


Several companies are implementing the chiplet model as a means to develop next-generation 3D-like chip designs, but this methodology still has a long way to go before it becomes mainstream for the rest of the industry. It takes several pieces to bring up a 3D chip design using the chiplet model. A few large players have the pieces, though most are proprietary. Others are missing some key co... » read more

Manufacturing Bits: July 13


Heterogenous III-V packaging At the recent 2021 IEEE 71st Electronic Components and Technology Conference (ECTC), a group presented a paper on the development of a wafer-level fan-out package using heterogenous III-V devices. This paper deals with the packaging of two III-V chips for use in RF transceiver applications in base stations. III-V Lab, CEA-Leti, Thales and United Monolithic Semic... » read more
