Abstract

See full text

An IC has cells placed in a cell row having a UTBOX-FDSOI pMOSFET including a ground beneath the pMOS, and an n-doped well beneath it and configured to apply a potential thereto, and a UTBOX-FDSOI nMOSFET including a ground beneath the nMOS, and a p-doped well beneath the ground and configured to apply a potential thereto, and cells, each including a UTBOX-FDSOI pMOSFET including a ground beneath the pMOS, and a p-doped well beneath the ground and configured to apply an electrical potential to the ground, and a UTBOX-FDSOI nMOSFET including a ground beneath the nMOS, and an n-doped well beneath the ground and configured to apply a potential thereto. The cells are placed so that pMOS's of standard cells belonging to a row align along it and a transition cell including a another well and contiguous with first row standard cells thus ensuring continuity with wells of those cells.
