Abstract

A semiconductor device and method of manufacture are provided which utilizes metallic seeds to help crystallize a ferroelectric layer. In an embodiment a metal layer and a ferroelectric layer are formed adjacent to each other and then the metal layer is diffused into the ferroelectric layer. Once in place, a crystallization process is performed which utilizes the material of the metal layer as seed crystals.
