Leti’s monolithic 3D technology, which has now been dubbed “CoolCube”, was featured in a recent EETimes piece. Entitled True 3D monolithic integration eliminates TSV dependence (click here to read it), the article covers a Leti paper presented during a 3D-VLSI workshop preceding IEDM ’14. Leti’s Advanced CMOS lab manager Maud Vinet detailed the “cool” process in an FPGA, stacking a 14nm FD-SOI logic layer on top of a memory layer. It eliminates the need for TSVs, shrinks area by 55%, cut power in half and increases speed by 30%, effectively gaining a full node in terms of power and performance.
