  • Publication number: 20070249166
    Abstract: A method is provided for fabricating a semiconductor component that includes a capacitor having a high capacitance per unit area. The component is formed in and on a semiconductor on insulator (SOI) substrate having a first semiconductor layer, a layer of insulator on the first semiconductor layer, and a second semiconductor layer overlying the layer of insulator. The method comprises forming a first capacitor electrode in the first semiconductor layer and depositing a dielectric layer comprising Ba1-xCaxTi1-yZryO3 overlying the first capacitor electrode. A conductive material is deposited and patterned to form a second capacitor electrode overlying the dielectric layer, thus forming a capacitor having a high dielectric constant dielectric. An MOS transistor in then formed in a portion of the second semiconductor layer, the MOS transistor, and especially the gate dielectric of the MOS transistor, formed independently of forming the capacitor and electrically isolated from the capacitor.

  • Patent number: 7253068
    Abstract: The silicon-on-insulator (SOI) arrangement provides dual SOI film thicknesses for body-resistance control and provides a bulk silicon substrate on which a buried oxide (BOX) layer is provided. The BOX layer has recesses formed therein and unrecessed portions. The silicon layer is formed on the BOX layer and closes the recesses and covers the unrecessed portions of the BOX layer. Shallow trench isolation regions define and isolate first silicon regions from second silicon regions that each include one of the recesses. Floating-body devices are formed within the first silicon regions, which exhibit a first thickness, and body-tied devices are formed within the second silicon regions that include the thicker silicon of the recesses.

  • Publication number: 20070032024
    Abstract: A method for fabricating a stressed MOS device in and on a semiconductor substrate is provided. The method comprises the steps of forming a gate electrode overlying the semiconductor substrate and etching a first trench and a second trench in the semiconductor substrate, the first trench and the second trench formed in alignment with the gate electrode. A stress inducing material is selectively grown in the first trench and in the second trench and conductivity determining impurity ions are implanted into the stress inducing material to form a source region in the first trench and a drain region in the second trench. To preserve the stress induced in the substrate, a layer of mechanically hard material is deposited on the stress inducing material after the step of ion implanting.

  • Publication number: 20070026599
    Abstract: Methods are provided for fabricating a stressed MOS device. The method comprises the steps of forming a plurality of parallel MOS transistors in and on a semiconductor substrate. The parallel MOS transistors having a common source region, a common drain region, and a common gate electrode. A first trench is etched into the substrate in the common source region and a second trench is etched into the substrate in the common drain region. A stress inducing semiconductor material that has a crystal lattice mismatched with the semiconductor substrate is selectively grown in the first and second trenches. The growth of the stress inducing material creates both compressive longitudinal and tensile transverse stresses in the MOS device channel that enhance the drive current of P-channel MOS transistors. The decrease in drive current of N-channel MOS transistors caused by the compressive stress component is offset by the tensile stress component.

  • Publication number: 20060258110
    Abstract: A method is provided for fabricating a semiconductor on insulator (SOI) device. The method includes, in one embodiment, providing a monocrystalline silicon substrate having a monocrystalline silicon layer overlying the substrate and separated therefrom by a dielectric layer. A gate electrode material is deposited and patterned to form a gate electrode and a spacer. Impurity determining dopant ions are implanted into the monocrystalline silicon layer using the gate electrode as an ion implant mask to form spaced apart source and drain regions in the monocrystalline silicon layer and into the monocrystalline silicon substrate using the spacer as an ion implant mask to form spaced apart device regions in the monocrystalline substrate. Electrical contacts are then formed that contact the spaced apart device regions.

  • Publication number: 20060197154
    Abstract: A semiconductor component having analog and logic circuit elements manufactured from an SOI substrate and a method for manufacturing the semiconductor component. An SOI substrate has a support wafer coupled to an active wafer through an insulating material. Openings are formed in the active wafer, extend through the insulating material, and expose portions of the support wafer. Epitaxial semiconductor material is grown on the exposed portions of the support wafer. Analog circuitry is manufactured from the epitaxially grown semiconductor material and high performance logic circuitry is manufactured from the active wafer. The processing steps for manufacturing the analog circuitry are decoupled from the steps for manufacturing the high performance logic circuitry. A substrate contact is made from a portion of the epitaxially grown semiconductor material that is electrically isolated from the portion in which the analog circuitry is manufactured.

  • Patent number: 6506654
    Abstract: Floating body effects are substantially reduced by strategically forming source-side stacking faults to create a leakage path from the body to the source of an SOI structure. Embodiments include ion implanting a heavy ion, such as Xe, to form a buried amorphous layer in the source-side of the silicon layer after source/drain implants followed by silicidation, during which the buried amorphous region recrystallizes creating source-side stacking faults.
