Fine-Pitch Copper Pillar With Bond On Lead (BOL).


Fine pitch copper (Cu) pillar bump adoption has been growing in high-performance and low-cost flip chip packages. Higher input/output (I/O) density and very fine pitch requirements are driving very small feature sizes such as small bump on a narrow pad or bond-on-lead (BOL) interconnection, while higher performance requirements are driving increased current densities. Assembling such packages u... » read more

Advanced Packaging Moves To Cars


By Ann Steffora Mutschler and Ed Sperling As automotive OEMs come up to speed on electrification of vehicles, each at their own pace, they are starting to embrace novel packaging approaches as a way to differentiate themselves in an increasingly competitive market. Wirebond used to dominate this market, where most of the chips were relatively unsophisticated and product cycles were slow�... » read more

28nm Chip-Package Interactions In Large eWLB FO-WLP


To meet the continued demand for form factor reduction and functional integration of electronic devices, Wafer Level Packaging (WLP) is an attractive packaging solution with many advantages in comparison with standard Ball Grid Array (BGA) packages. The advancement of fan-out WLP has made it a more promising solution as compared with fan-in WLP, because it can offer greater flexibility in enabl... » 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

Shrink Or Package?


Advanced packaging is rapidly becoming a mainstream option for chipmakers as the cost of integrating heterogeneous components on a single die continues to rise. Despite several years of buzz around this shift, the reality is that it has taken more than a half-century to materialize. Advanced [getkc id="27" kc_name="packaging"] began with IBM flip chips in the 1960s, and it got another boost ... » read more

Security Issues Up With Heterogeneity


The race toward heterogeneous designs is raising new security concerns across the semiconductor supply chain. There is more IP to track, more potential for unexpected interactions, and many more ways to steal data or IP. Security is a difficult problem no matter what kind of chip is involved, and it has been getting worse as more devices, machines and systems are connected to the Internet. B... » read more

Board Level Reliability Improvement In eWLB


When it comes to reducing form-factor and increasing functional integration of mobile devices, Wafer Level Packaging (WLP) is an attractive packaging solution with many advantages in comparison to standard Ball Grid Array (BGA) packages. With the advancement of various fan-out WLP (FOWLP), it is a more optimal and promising solution compared to fan-in WLP because it can offer greater flexibilit... » 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

Ultra-Thin Substrate Assembly Challenges For Advanced Flip Chip Package


Advanced semiconductor packaging requirements for higher and faster performance in a thinner and smaller form factor continues to grow for mobile, network and consumer devices. While the increase in device input/output (I/O) count is driven by the famous “Moore’s Law”, the packaging industry is experiencing opposing trends for more complex packaging solutions while the expected cost targe... » read more
