Highly manufacturable 90 nm NOR flash technology with 0.081 /spl mu/m/sup 2/ cell size
A manufacturable 90 nm NOR Flash technology has been developed with extremely small cell size of 0.081/spl mu/m/sup 2/, which is the smallest cell size of NOR cell, for high density code storage memory featuring with low voltage operation. The small cell size of 0.081/spl mu/m/sup 2/ is successfully...

Summary: | A manufacturable 90 nm NOR Flash technology has been developed with extremely small cell size of 0.081/spl mu/m/sup 2/, which is the smallest cell size of NOR cell, for high density code storage memory featuring with low voltage operation. The small cell size of 0.081/spl mu/m/sup 2/ is successfully achieved with three key main technologies such as an advanced KrF lithography with off-axis illumination system, appropriate dielectric thin film and junction scaling and optimized oxidation encroachment of inter-poly oxide nitride oxide (ONO) and tunnel oxide. |
