Samsung 70nm design technology |
Five generations of NAND flash memory have been introduced consecutively: 256Mb in 1999, 512Mb in 2000, 1Gb in 2001, 2Gb in 2002, 4Gb in 2003 and 8Gb in 2004. The use of 70nm design technology to produce the 4Gb NAND flash enables Samsung to produce the industry’s smallest memory cell size - 0.025um2 (25/1000 micrometers). An advanced Argon fluoride photo-lithography light source has been deployed to etch the finer circuitry permitted by the 70nm process.
Samsung 4 Gigabit NAND flash
Samsung’s 70nm 4Gb NAND flash writes data at 16-megabytes per second, a 50 percent enhancement over a 90nm 2Gb device, thereby enabling real time data storage of high-definition (HD) video images. According to market research firm Gartner Dataquest, 4Gb NAND flash will account for more than 30% of total expected sales of $8 billion in NAND flash memory this year.
Samsung first wafer-out - 300mm wafer line
Samsung also announced the first wafer-out at its new 300mm wafer fabrication line, one month ahead of schedule. The 300mm wafer line, Samsung’s Line 14, initially will produce 4,000 wafers starts per month and gradually ramp up to 15,000 wafer starts by the end of 2005. Line 14 produces 70nm 4Gb NAND and 90nm 2Gb NAND flash memory.
