Why SOI, why now?

Silicon-on-insulator (SOI) technology electrically insulates a fine layer of the monocrystalline silicon from the rest of the silicon wafer. This opens up new avenues for innovation, delivering performance, power and area (PPA) advantages that bulk CMOS technologies cannot easily match.

And, the SOI manufacturing process is actually simpler than bulk-based CMOS processes. In bulk, isolation and other processes continue to grow in complexity and cost with scaling. Recent studies indicate that overall SOI solutions can be cost-neutral or even cheaper than bulk silicon.
