There’s been a significant uptick in patents related to fully-depleted SOI, according to a new report by KnowMade (click here to get the report brochure). The report looks at both FD-SOI and SOI-FinFETs (both of which are fully depleted technologies). More than 740 patent families have been published to date, of which planar FD-SOI accounts for 340 families. Following a rush of activity about 10 years ago there was a dip, but activity over the last couple of years has once again been very strong.
The report provides a comprehensive overview, essential patent data for fully depleted SOI, plus a searchable database with links. It identifies more than 30 patent holders of FD-SOI related intellectual property, providing in-depth analysis of key technology segments and key players. “The major proponents of the FD-SOI technology have strong IP arms, but other unexpected players known as not supporting FDSOI [including TSMC and Intel] are also present,” notes the report.
