I'm not sure what you mean by 0.09 lambda.  Have you set lambda to 90 
nanometers?  Or are you actually placing things on .09 grid units in 
Electric?  If you are doing 90 nanometer design, be aware that CIF has a 
granularity of 100 nanometers, so it is really not appropriate for small 
features.  If you are placing things on .09 lambda grid units, be aware 
that Electric represents each grid unit as only 120 integer parts, and so 
.09 will be rounded.

You should probably switch to GDS for small feature design.
