UMC Rockets 17%. SST, UMC Announce Availability of 28nm SuperFlash Gen 4 Platform

Tiger Newspress01-20

United Microelectronics stock rocketed about 17% on Tuesday. Silicon Storage Technology, a subsidiary of Microchip Technology and United Microelectronics Corporation announced that they have completed full qualification and release to production of SST’s embedded SuperFlash Gen 4 with full automotive grade 1 capability on UMC’s 28HPC+ foundry process platform.

SST developed ESF4 in close partnership with UMC to deliver enhanced embedded non-volatile memory performance and demonstrated reliability for automotive controllers while simultaneously significantly reducing the number of additional masking steps versus other foundries’ 28nm High-k/Metal-Gate Stack eFlash offerings, bringing customers cost advantages and greater manufacturing efficiency.
