Fan-Outs vs. TSVs


Two years ago, at the annual IMAPS conference on 2.5D and 3D chip packaging, the presentations were dominated by talk of fan-out wafer-level packaging. There was almost no talk of through-silicon vias, which previously had been heralded as vital to 2.5D and 3DIC packaging. Fast forward to this month's 3D Architectures for Heterogeneous Integration and Packaging conference in Burlingame, Cali... » read more

Advanced Packaging Is Suddenly Very Cool


The hottest chip markets today—automotive AI for autonomous and heavily assisted driving, machine learning, virtual and augmented reality—all are beginning to look at advanced packaging as the best path forward for improving performance and reducing power. Over the past four years, which is when 2.5D and fan-out wafer-level packaging first really began garnering interest, these and othe... » read more

Advanced Packaging Picks Up Steam


The semiconductor industry’s push toward continued miniaturization and increasing complexity is driving wider adoption of system-in-package (SiP) technology. One of the big benefits of [getkc id="199" kc_name="SiP"] is that it allows more features to be squeezed into ever-smaller form factors, such as wearable gadgets and medical implants. So while the individual chips in this package may ... » read more

Challenges For Future Fan-Outs


The fan-out wafer-level packaging market is heating up. At the high end, for example, several packaging houses are developing new fan-out packages that could reach a new milestone and hit or break the magic 1µm line/space barrier. But the technology presents some challenges, as it may require more expensive process flows and equipment like lithography. Fig. 1: Redistribution layers. Source: L... » read more

New BEOL/MOL Breakthroughs?


Chipmakers are moving ahead with transistor scaling at advanced nodes, but it's becoming more difficult. The industry is struggling to maintain the same timeline for contacts and interconnects, which represent a larger portion of the cost and unwanted resistance in chips at the most advanced nodes. A leading-edge chip consists of three parts—the transistor, contacts and interconnects. The ... » read more

What’s Next In Scaling, Stacking


An Steegen, executive vice president of semiconductor technology and systems at [getentity id="22217" e_name="Imec"], sat down with Semiconductor Engineering to discuss IC scaling, chip stacking, packaging and other topics. Imec is an R&D organization in Belgium. What follows are excerpts of that conversation. SE: Chipmakers are shipping 16nm/14nm processes with 10nm and 7nm technologies... » read more

2.5D, Fan-Out Inspection Issues Grow


As advanced packaging moves into the mainstream, packaging houses and equipment makers are ratcheting up efforts to solve persistent metrology and inspection issues. The goal is to lower the cost of fan-outs, [getkc id="82" kc_name="2.5D"] and [getkc id="42" kc_name="3D-IC"], along with a number of other packaging variants consistent with the kinds of gains that are normally associated with Moo... » read more

Wirebond Technology Rolls On


Several years ago, many predicted the demise of an older interconnect packaging technology called wire bonding, prompting the need for more advanced packaging types. Those predictions were wrong. The semiconductor industry today uses several advanced packaging types, but wire bonding has been reinvented over the years and remains the workhorse in packaging. For example, Advanced Semiconducto... » read more

Intel Inside The Package


Mark Bohr, senior fellow and director of process architecture and integration at Intel, sat down with Semiconductor Engineering to discuss the growing importance of multi-chip integration in a package, the growing emphasis on heterogeneity, and what to expect at 7nm and 5nm. What follows are excerpts of that interview. SE: There’s a move toward more heterogeneity in designs. Intel clearly ... » read more

Electroplating IC Packages


The electrochemical deposition (ECD) equipment market for IC packaging is heating up as 2.5D, 3D and fan-out technologies begin to ramp. [getentity id="22817" e_name="Applied Materials"]  recently rolled out an ECD system for IC packaging. In addition, Lam Research, TEL and others compete in the growing but competitive ECD equipment market for packaging. ECD—sometimes referred to as pl... » read more
