 SOI was first commercialized in 1995, when Shahidi's work on SOI convinced John Kelly, who ran IBM's server division, to adopt SOI in the AS/400 line of server products, which used 220 nm CMOS with copper metallization SOI devices.In early 2001, he used SOI to developed a low-power RF CMOS device, resulting in increased radio frequency.Later that year, IBM was set to introduce 130 nanometer CMOS SOI devices with copper and low-κ dielectric for the back end, based on Shahidi's work.
