Peregrine Semiconductor and MagnaChip Announce Completed the Final Qualification Phase in the Process Technology Transfer of Peregrine’s UltraCMOS SOS (Silicon-On-Sapphire) Technology to MagnaChip’s Cheongju Wafer Manufacturing Facility
The UltraCMOS process is a patented silicon-on-sapphire technology (SOS) that has for years been recognized as a technically superior semiconductor vehicle reserved for highly specialized military and space projects. SOS was thought to be impossible to manufacture in commercial volumes at a reasonable cost. Overcoming these challenges without sacrificing the inherent benefits of the technology took several years of research and development, all now protected by dozens of patents. The UltraCMOS p
