2.5D Becomes A Reality


Semiconductor Engineering sat down to discuss 2.5D and advanced packaging with Max Min, senior technical manager at [getentity id="22865" e_name="Samsung"]; Rob Aitken, an [getentity id="22186" comment="ARM"] fellow; John Shin, vice president at [getentity id="22903" e_name="Marvell"]; Bill Isaacson, director of ASIC marketing at [getentity id="22242" e_name="eSilicon"]; Frank Ferro, senior di... » read more

Power Management Heats Up


Power management has been talked about a lot recently, especially when it comes to mobile devices. But power is only a part of the issue—and perhaps not even the most important part. Heat is the ultimate limiter. If you cannot comfortably place the device on your face or wrist, then you will not have a successful product. Controlling heat, at the micro and macro levels, is an important asp... » read more

How Many Cores? (Part 2)


New chip architectures and new packaging options—including fan-outs and 2.5D—are changing basic design considerations for how many cores are needed, what they are used for, and how to solve some increasingly troublesome bottlenecks. As reported in part one, just adding more cores doesn't necessarily improve performance, and adding the wrong size or kinds of cores wastes power. That has s... » read more

Timing Is Everything


It's easy to look back on companies or products that missed the market because they were too early. Remember the Eo? The brick-like personal digital assistant that AT&T introduced in 1993 had an antenna that hinted at 4G connectivity. Unfortunately, there was no 4G available at the time, so it was just an extra wire. (Check out the video of the tablet version here.) The EO 440 Personal... » read more

Reducing Post-Placement Leakage With Stress-Enhanced Fill Cells


By Valeriy Sukharev, Jun-Ho Choy, Armen Kteyan and Henrik Hovsepyan As downward scaling of transistors continues, optimizing power consumption for mobile devices is a major concern. Power consumption consists of two components: dynamic and static. Dynamic (active) power is used while the chip is performing various functions, while static (leakage) power is consumed by leakage current (Figure... » read more

Inside Advanced Packaging


Semiconductor Engineering sat down to discuss advanced IC-packaging, the OSAT industry, China and other topics with Ron Huemoeller, vice president of worldwide R&D at Amkor. What follows are excerpts of that conversation. SE: Where are we in advanced IC-packaging today? Huemoeller: We’ve hit the inflection point. Now we are coming to the other side of it. Regarding this need to int... » read more

Will 3D-IC Work?


Advanced packaging is becoming real on every level, from fan-outs to advanced fan-outs, 2.5D, and 3D-ICs for memory. But just how far 3D and monolithic 3D will go isn't clear at this point. The reason is almost entirely due to heat. In a speech at SEMI's Integrated Strategy Symposium in January, Babek Sabi, Intel corporate VP and director of assembly and test technology development, warned t... » read more

Thermal Damage To Chips Widens


Heat is becoming a much bigger problem for semiconductor and system design, fueled by higher density and the increasing use of complex chips in markets such as automotive, where reliability is measured in decade-long increments. In the past, heat typically was handled by mechanical engineers, who figured out where to put heat sinks, fans, or holes to funnel heat out of a chassis. But as more... » read more

Fallout From Scaling


By Ed Sperling & Ann Steffora Mutschler Semiconductor scaling is becoming much more difficult and expensive at each new node, creating sharp divisions about what path to take next for which markets and applications. What used to be confined to one or two clear choices is now turning into a menu of items and possibilities, often with no clear guarantees for a successful outcome. Views ... » read more
