One of the greatest obstacles standing between chip manufacturers and the pursuit of smaller, faster, processors is the lack of a proper light source. Current chips are etched using a deep ultraviolet wavelength of 193nm, but at a 28nm semiconductor process geometry, we've reached the limits of what a 193nm wavelength is small enough to etch, even when using immersion lithography (in which the chip is immersed in water). Extreme ultraviolet lithography (EUV) has been pegged as the most likely replacement for current 193nm technology, but repeated problems with ramping EUV have left it stalled on the runway. Now, for the first time, foundry technology developer ASML, which made headlines last...

Continuing its advancements into smaller manufacturing processes, Toshiba America Electronic Components, Inc. (TAEC) announced this week that it has developed second generation 19 nanometer process technology that will be used in the mass production of 2-bit-per-cell 64-gigabit NAND memory chips. Toshiba's already used the technology the develop what it claims is the world's smallest 2-bit-per-cell 64Gb NAND memory chips, which measure a scant 94 square millimeters in size. That's a 25 percent reduction over previous technology. Though small in size, the chips are capable of writing 25 megabytes of data per second, the world's fastest class in 2-bit-per-cell territory, according to Toshiba. The...

To make a dent in the mobile market, companies have to make things smaller, denser, and then do it again. The latest effort along those lines from SanDisk is a 19nm 128Gb NAND flash memory chip that employs the company’s X3 (three bits per cells) technology to hit a reported write performance of 18MB/s. SanDisk is looking to expand its X3 technology into other product categories, notable with MLC NAND flash. The company also mentioned a 64Gb X3 chip for the microSD format. Production of the 19nm chip should help boost both its OEM and retail businesses.
