Abstract
An integrated circuit may include an SOI substrate having a buried insulating layer, and a semiconductor film above the buried insulating layer. The semiconductor film may have first patterns in a first zone defining gate regions of first MOS transistors and also first dummy gate regions. The first zone may include two domains having a space therebetween, and the space may be filled by at least one insulating material and be situated between two dummy gate regions above a region of the supporting substrate without any insulating trench.
