Infineon Technologies AG and Nanya Technology Corporation yesterday announced the successful
qualification of 90nm DRAM technology which was jointly developed at Infineon?s Research Center in
Dresden, Germany.
Both companies have already qualified the 90nm memory products at major customers and achieved
validation of Intel. DRAM volume production with 90nm process structures on 300mm has first started at
Infineon?s 300mm production line in Dresden. Being the second DRAM manufacturer worldwide introducing
90nm technology, Infineon has already converted by end of May around 5 percent of its total global DRAM
production from 110nm to 90nm. Inotera Memories, the Taiwan-based manufacturing joint venture of Infineon
and Nanya is starting the 90nm transition now. Early adoption of the next generation technology node
allows to significantly improve production costs and product performances and is one of the most important
factors to increase profitability in DRAM manufacturing.
Process structures of 90nm further reduce chip size compared to the previous 110nm technology thereby
increasing potential chip output per wafer by more than 30 percent. The expected productivity increase by
shrinking the chip size combined with the use of 300mm wafers is the basis for a significant reduction of
production cost per chip. The strategic development alliance of Infineon and Nanya also covers the next
technology node with 70nm structures.
Except for its cost advantage, transition to smaller process geometries is crucial for high-speed and
low-power DDR2 and DDR3 SDRAM in an increasingly mobile world. With the validation and customer
qualification of the first component, a 512Mb DDR SDRAM, Infineon and Nanya are the industry?s second
DRAM manufacturers to introduce the 90nm technology node. The extension of the portfolio with a 512Mb
DDR2 SDRAM is expected in the second half of 2005. A variety of other products including 256Mb DDR2
and 1G DDR2 are to follow later on.
