3D-IC Ecosystem Starts To Take Form

Before any advancement can go mainstream, it requires an ecosystem. Chiplets are a first step.

The adoption of chiplets is inevitable, but exactly when a mass migration toward this design approach will begin is yet to be determined.

Nevertheless, some of the biggest technological and business-related barriers are being addressed. And while a chiplet-based design remains beyond the economic reach of many companies today, that is starting to change. Early signs of an emerging ecosystem already are showing up.

Not long ago, the chip industry believed that the only companies that use chiplets were those with no other choice. There was a long list of reasons why this approach didn’t make sense, including cost, performance, and added design complexity. The trend of consolidation and integration onto a monolithic die seemed to be the path into the future.
