Intel, Micron debut 34nm NAND flash Mark LaPedus, EE Times, Jun
2, 2008
Analysts were impressed. Intel and Micron have basically leapfrogged the
competition, said Gregory Wong, an analyst with Forward Insights Co.
The main competition includes Hynix, Samsung and Toshiba/SanDisk.
Sub-40nm debut
"Owing to the aggressive gate half-pitch, immersion lithography
with self-aligned double patterning employing spacers is most likely
being used" by IM Flash to produce the latest part, Wong said in an
e-mail regarding the part. "Also expect changes in the bitline and
wordline materials as well as a higher k interpoly dielectric in
comparison to the 50nm generation."
Other vendors are not far behind. "If the ramp of IMFT's (IM Flash)
50nm 16Gbits device is any guide, we should expect to see volume in
December or in Q1 09," Wong said.
"It's quite remarkable that Intel-Micron have managed to catch up
and surpass the other NAND flash vendors in the short span of three
years," he added. "IM Flash achieved this milestone by skipping the
6xnm and 4xnm nodes. However, any cost advantage could be
short-lived if IM Flash fails to ramp up the technology smoothly and
SanDisk/Toshiba ramps its 43nm 32Gbit x3 in Q1 09 as planned.''
