Abstract: A method for forming a crystalline high-k dielectric layer and controlling the crystalline phase and orientation of the crystal growth of the high-k dielectric layer during an anneal process. The crystalline phase and orientation of the crystal growth of the dielectric layer may be controlled using seeding sections of the dielectric layer serving as nucleation sites and using a capping layer mask during the anneal process. The location of the nucleation sites and the arrangement of the capping layer allow the orientation and phase of the crystal growth of the dielectric layer to be controlled during the anneal process. Based on the dopants and the process controls used the phase can be modified to increase the permittivity and/or the ferroelectric property of the dielectric layer.
