Cheaper Packaging Options Ahead

Lower-cost packaging options and interconnects are either under development or just being commercialized, all of which could have a significant impact on the economics of advanced packaging. By far, the most cited reason why companies don't adopt advanced [getkc id="27" kc_name="packaging"] is cost. Currently, silicon [getkc id="204" kc_name="interposers"] add about $30 to the price of a med... » read more

Warp Speed Ahead

The computing world is on a tear, but not just in one direction. While battery-powered applications are focused on extending the time between charges or battery replacements, there is a whole separate and growing market for massive improvements in speed. Ultimately, this is where quantum computing will play a role, probably sometime in the late 2020/early 2030 timeframe, according to multipl... » read more

Advanced Packaging Still Not So Simple

The promise of advanced packaging comes in multiple areas, but no single packaging approach addresses all of them. This is why there is still no clear winner in the packaging world. There are clear performance benefits, because the distance between two chips in a package can be significantly shorter than the distance that signals have to travel from one side of a die to another. Moreover, wi... » read more

What’s What In Advanced Packaging

Ever open the body of your smartphone (perhaps unintentionally) and see small, black rectangles stuck on a circuit board? Those black rectangles are packaged chips. The external chip structure protects the fragile integrated circuits inside, as well as dissipates heat, keeps chips isolated from each other, and, importantly, provides connection to the circuit board and other elements. The manufa... » read more

Noise Abatement

[getkc id="285" kc_name="Noise"] is a fact of life. Almost everything we do creates noise as a by-product and quite often what is a signal to one party is noise to another. Noise cannot be eliminated. It must be managed. But is noise becoming a larger issue in chips as the technology nodes get smaller and packaging becomes more complex? For some, the answer is a very strong yes, while for ot... » read more

Packaging Enters New Phase

The race is on to make advanced packaging less expensive than shrinking everything down onto the same die—much less expensive, in fact. Following several years of speculation and rather shaky market predictions at the beginning of this decade, packaging houses and foundries spent the last four years proving that packaging really does provide a viable alternative to shrinking die in terms o... » 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

2.5D Adds Test Challenges

OSATs and ATE vendors are making progress in determining what works and what doesn't in 2.5D packaging, expanding their knowledge base as this evolves into a mainstream technology. A [getkc id="82" kc_name="2.5D"] package generally includes an ASIC connected to a stack of memory chips—usually high-bandwidth memory—using an [getkc id="204" kc_name="interposer"] or some type of silicon bri... » read more

Electrothermal Mechanical Stress Reference Design Flow For Printed Circuit Boards And Electronic Packages

This paper presents a reference design flow for solving the electrical, thermal and mechanical challenges of a printed circuit board (PCB) using simulation tools from ANSYS. This approach can be utilized for all electrical CAD (ECAD) types such as IC packages, touch panel displays, and glass and silicon interposers. The authors followed this reference design flow for analyzing a PCB virtual pro... » read more

More Degrees Of Freedom

Ever since the publication of Gordon Moore's famous observation in 1965, the semiconductor industry has been laser-focused on shrinking devices to their practical, and more recently, impractical limit. Increasing transistor density has encountered a number of problems along the way, but it also has enabled us to put computers—which once filled specially built rooms—onto the desktop firs... » read more
