Chiplets: Current Status


Recent weeks have seen a number of interesting developments in the area of chiplets. An increasing number of products based on chiplets have been brought to market, especially in the processors segment. For example, Apple and AMD now have processors with chiplets on the market and under production in high volumes. On one hand, this means that sufficient production capacity has now been built up... » read more

Heterogeneous Integration Using Organic Interposer Technology


As the costs of advanced node silicon have risen sharply with the 7 and 5-nanometer nodes, advanced packaging is coming to a crossroad where it is no longer fiscally prudent to pack all desired functionality into a single die. While single-die packages will still be around, the high-end market is shifting towards multiple-die packages to reduce overall costs and improve functionality. This shif... » read more

Fan-Out And Packaging Challenges


Semiconductor Engineering sat down to discuss various IC packaging technologies, wafer-level and panel-level approaches, and the need for new materials with William Chen, a fellow at ASE; Michael Kelly, vice president of advanced packaging development and integration at Amkor; Richard Otte, president and CEO of Promex, the parent company of QP Technologies; Michael Liu, senior director of globa... » read more

Interconnects Emerge As Key Concern For Performance


Interconnects are becoming increasingly challenging to design, implement and test as the amount of data skyrockets and the ability to move that data through denser arrays of compute elements and memories becomes more difficult. The idea of an interconnect is rather simple, but ask two people what constitutes an interconnect and you're likely to get very different answers. Interconnects are e... » read more

What’s After PAM-4?


[This is part 2 of a 2-part series. Part 1 can be found here.] The future of high-speed physical signaling is uncertain. While PAM-4 remains one of the key standards today, there is widespread debate about whether PAM-8 will succeed it. This has an impact on everything from where the next bottlenecks are likely to emerge and the best approaches to solving them, to how chips, systems and p... » read more

Making Silicon Photonics Chips More Reliable


Silicon photonics has the ability to dramatically improve on-die and chip-to-chip communication within a package at extremely low power, but ensuring that signal integrity remains consistent over time isn't so simple. While this technology has been used commercially for at least the past decade, it never has achieved mainstream status. That's mostly due to the fact that Moore's Law scaling h... » read more

Return Of The Organic Interposer


Organic interposers are resurfacing as an option in advanced packaging, several years after they were first proposed as a means of reducing costs in 2.5D multi-die configurations. There are several reasons why there is a renewed interest in this technology: More companies are pushing up against the limits of Moore's Law, where the cost of continuing to shrinking features is exorbitant. ... » read more

Extending The IC Roadmap


An Steegen, executive vice president of semiconductor technology and systems at Imec, sat down with Semiconductor Engineering to discuss IC scaling and chip packaging. Imec is working on next-generation transistors, but it is also developing several new technologies for IC packaging, such as a proprietary silicon bridge, a cooling technology and packaging modules. What follows are excerpts of t... » read more

System Bits: Dec. 12


Increasing performance scaling with packageless processors Demand for increasing performance is far outpacing the capability of traditional methods for performance scaling. Disruptive solutions are needed to advance beyond incremental improvements. Traditionally, processors reside inside packages to enable PCB-based integration. However, a team of researchers from the Department of Electrical ... » read more

The Week In Review: IoT


Deals Advanced Semiconductor Engineering was selected by zGlue as its strategic manufacturing partner. The ASE Group will make the zGlue Integrated Platform, which is said to enable customization for consumer and industrial IoT markets. The ZiP integrates hardware and software in a modular 3DIC-based platform. ASE will assemble zGlue-certified chiplets for connecting through zGlue Smart Fabric... » read more
