The TSMC Technology Symposium provides a worldwide stage for TSMC to showcase its advanced technology impact and the extensive ecosystem that is part of the company’s vast reach. These events occur around the world and the schedule is winding down. TSMC covers many topics at its Technology Symposium, including industry-leading HPC, smartphone, IoT, and automotive platform solutions, 5nm, 4nm, 3nm, 2nm processes, ultra-low power, RF, embedded memory, power management, sensor technologies, and AI enablement. Capacity expansion and green manufacturing achievements were also discussed, along with TSMC’s Open Innovation Platform^® ecosystem. These represent significant achievements for sure. For this post, I’d like to focus on another set of significant achievements in advanced packaging. This work has substantial implications for the future of the semiconductor industry. Let’s examine how TSMC advanced packaging overcomes the complexities of multi-die design.

Why Advanced Packaging is Important

Advanced packaging is a relatively new addition to the pure-play foundry model. It wasn’t all that long ago that packaging was a not-so-glamorous finishing requirement for a chip design that was outsourced to third parties. The design work was done by package engineers who got the final design thrown over the wall to fit into one of the standard package configurations. Today, package engineers are the rock stars of the design team. These folks are involved at the very beginning of the design and apply exotic materials and analysis tools to the project. The project isn’t real until the package engineer signs off that the design can indeed be assembled.

With this part of the design process becoming so critically important (and difficult) it’s no surprise that TSMC and other foundries stepped up to the challenge and made it part of the overall set of services provided. The driver for all this change can be traced back to three words: exponential complexity increase. For many years, exponential complexity increase was delivered by Moore’s Law in the form of larger and larger monolithic chips. Today, it takes more effort and cost to get to the next process node and when you finally get there the improvement isn’t as dramatic as it once was. On top of that, the size of new designs is so huge that it can’t fit on a single chip.
