X-FAB Silicon Foundries is now able to support volume heterogeneous integration via Micro-Transfer Printing (MTP), thanks to a licensing agreement that has just been secured with X-Celeprint. This will mean that a diverse range of semiconductor technologies may be combined together, each being optimized for particular functional requirements. These will include SOI, GaN, GaAs and InP, as well as MEMS.
In order to become the first foundry to provide customers with MTP-based heterogeneous integration, X-FAB has made substantial investments over the last two years. It has also established new optimized workflows and cleanroom protocols. This will allow customers to work with the foundry on heterogeneous design projects — benefitting from a low-risk and fully scalable business model that offers a clear migration to volume production.
X-Celeprint’s proprietary massively-parallel pick-and-place MTP technology stacks and fans-out ultra-thin dies based on different process nodes, technologies, and wafer sizes. It results in the formation of virtually monolithic 3D stacked ICs, which have enhanced performance, greater power efficiency, and take up less space. Furthermore, all this can be achieved at an accelerated rate, thereby significantly shortening time-to-market.
