They call me the “Queen of 3D” because I have been following the course of 3D integration and blogging about it since 2009. Francoisein3D is the featured blog on this…

XilixVU440The Xilinx Ultrascale VU440 3D FPGA is constructed using “Xinterposer” 3D IC technology jointly developed by Xilinx and TSMC. It uses a low-k dielectric chip fabricated on 20nm silicon node with a total of 375,000 micron bumps stacked on 25mm x 45mm silicon interposer and assembled with CoWoS. The composite 3D FPGA consists of approximately 19 billion transistors.

The Ultrascale VU440 represents a silicon interposer product on the largest interposer fabricated with a size exceeding the reticle. Field stitching is used for the lithography as it surpasses the size of the reticle. The Interposer is mounted with C4 bumps on a 55mm x 55mm organic substrate. The silicon interposer has acceptable warpage/coplanarity and passed 1,000 TCB and 1,000 hours HTS without any failure or voiding in the low-k, micro bumps or C4 bumps.
