Abstract:
1. An integrated circuit device comprising: a substrate having first and second portions; one or more first active regions formed in the first portion of the substrate, wherein each of the one or more first active regions has rounded corners; a first dielectric layer formed on opposing sidewalls of the one or more first active regions; a first isolation region formed on each of the first dielectric layers so that a sidewall of each first isolation region is flush with an end of the first dielectric layer on which that first isolation region is formed; one or more first circuit elements formed on the one or more first active regions, wherein corners of the one or more first active regions have been rounded prior to forming the first circuit elements thereon; one or more second active regions formed in the second portion of the substrate; and one or more second circuit elements formed on the one or more second active regions.
