Making Chip Packaging More Reliable


Packaging houses are readying the next wave of IC packages, but these products must prove to be reliable before they are incorporated into systems. These packages involve several advanced technologies, such as 2.5D/3D, chiplets and fan-out, but vendors also are working on new versions of more mature package types, like wirebond and leadframe technologies. As with previous products, packaging... » read more

What Goes Wrong In Advanced Packages


Advanced packaging may be the best way forward for massive improvements in performance, lower power, and different form factors, but it adds a whole new set of issues that were much better understood when Moore's Law and the ITRS roadmap created a semi-standardized path forward for the chip industry. Different advanced packaging options — system-in-package, fan-outs, 2.5D, 3D-IC — have a... » read more

System-Level Packaging Tradeoffs


Leading-edge applications such as artificial intelligence, machine learning, automotive, and 5G, all require high bandwidth, higher performance, lower power and lower latency. They also need to do this for the same or less money. The solution may be disaggregating the SoC onto multiple die in a package, bringing memory closer to processing elements and delivering faster turnaround time. But ... » read more

The Race To Much More Advanced Packaging


Momentum is building for copper hybrid bonding, a technology that could pave the way toward next-generation 2.5D and 3D packages. Foundries, equipment vendors, R&D organizations and others are developing copper hybrid bonding, which is a process that stacks and bonds dies using copper-to-copper interconnects in advanced packages. Still in R&D, hybrid bonding for packaging provides mo... » read more

Hidden Soldier Joints Inspection: 4 Case Studies


IC packaging technologies are becoming smaller and thinner. Ball grid array (BGA) packages were introduced some years ago in order to save space on the PCB, and are now widely used. To overcome the resulting problems with using optical microscopy as an inspection tool, the endoscope found its way into quality engineering departments. To read more, click here. » read more

Focus Shifting From 2.5D To Fan-Outs For Lower Cost


Semiconductor Engineering sat down to discuss advanced packaging with Calvin Cheung, vice president of engineering at ASE; Walter Ng, vice president of business management at UMC; Ajay Lalwani, vice president of global manufacturing operations at eSilicon; Vic Kulkarni, vice president and chief strategist in the office of the CTO at ANSYS; and Tien Shiah, senior manager for memory at Samsung. W... » read more

Lithography Challenges For Fan-out


Higher density fan-out packages are moving toward more complex structures with finer routing layers, all of which requires more capable lithography equipment and other tools. The latest high-density fan-out packages are migrating toward the 1µm line/space barrier and beyond, which is considered a milestone in the industry. At these critical dimensions (CDs), fan-outs will provide better per... » read more

EDA Grabs Bigger Slice Of Chip Market


EDA revenues have been a fairly constant percentage of semiconductor revenues, but that may change in 2019. With new customers creating demand, and some traditional customers shifting focus from advanced nodes, the various branches of the EDA tool industry may be where sticky technical problems are solved. IC manufacturing, packaging and development tools all are finding new ways to handle t... » read more

Top Tech Talks Of 2018


2018 shaped up to be a year of transition and inflection, sometimes in the same design. There were new opportunities in automotive, continued difficulties in scaling, and an explosion in AI and machine learning everywhere. Traffic numbers on stories give a snapshot of the most current trends, but with videos those trends are even more apparent because of the time invested in watching those v... » read more

Packaging Biz Faces Challenges in 2019


The IC packaging industry is bracing for slower growth, if not uncertainty, in 2019, even though advanced packaging remains a bright spot in the market. Generally, IC packaging houses saw strong demand in the first part of 2018, but the market cooled in the second half of the year due to a slowdown in memory. Going forward, the slower IC packaging market is expected to extend into the first ... » read more
