A method of forming a semiconductor structure having a ferroelectric memory (FEM) gate unit on a substrate of single crystal silicon includes: forming a silicon device area for the FEM gate unit; treating the device area to form area for a source, gate and drain region; depositing an FEM gate unit over the gate junction region, including depositing a lower electrode, depositing a c-axis oriented Pb5Ge3O11 FE layer by Chemical vapor deposition (CVD), and depositing an upper electrode; and depositing an insulating structure about the FEM gate unit. A ferroelectric memory (FEM) cell includes: a single-crystal silicon substrate including an active region having source, gate and drain regions therein; a FEM gate unit including a lower electrode, a c-axis oriented Pb5Ge3O11 FE layer formed by CVD and an upper electrode; an insulating layer, having an upper surface, overlying the junction regions, the FEM gate unit and the substrate; and a source, gate and drain electrode. <IMAGE> |
