  • Publication number: 20100252810
    Abstract: Methodologies and gate etching processes are presented to enable the fabrication of gate conductors of semiconductor devices, such as NFETs and/or PFETs, which are equipped with nano-channels. In one embodiment, a sacrificial spacer of equivalent thickness to the diameter of the gate nano-channel is employed and is deposited after patterning the gate conductor down to the gate dielectric. The residue gate material that is beneath the nano-channel is removed utilizing a medium to high density, bias-free, fluorine-containing or fluorine- and chlorine-containing isotropic etch process without compromising the integrity of the gate. In another embodiment, an encapsulation/passivation layer is utilized. In yet further embodiment, no sacrificial spacer or encapsulation/passivation layer is used and gate etching is performed in an oxygen and nitrogen-free ambient.

  • Patent number: 7767503
    Abstract: Channel depth in a field effect transistor is limited by an intra-layer structure including a discontinuous film or layer formed within a layer or substrate of semiconductor material. Channel depth can thus be controlled much in the manner of SOI or UT-SOI technology but with less expensive substrates and greater flexibility of channel depth control while avoiding floating body effects characteristic of SOI technology. The profile or cross-sectional shape of the discontinuous film may be controlled to an ogee or staircase shape to improve short channel effects and reduce source/drain and extension resistance without increase of capacitance. Materials for the discontinuous film may also be chosen to impose stress on the transistor channel from within the substrate or layer and provide increased levels of such stress to increase carrier mobility. Carrier mobility may be increased in combination with other meritorious effects.

  • Patent number: 7749842
    Abstract: A method and device providing a strained Si film with reduced defects is provided, where the strained Si film forms a fin vertically oriented on a surface of a non-conductive substrate. The strained Si film or fin may form a semiconductor channel having relatively small dimensions while also having few defects. The strained Si fin is formed by growing Si on the side of a relaxed SiGe block. A dielectric gate, such as, for example, an oxide, a high “k” material, or a combination of the two, may be formed on a surface of the strained Si film. Additionally, without substantially affecting the stress in the strained Si film, the relaxed SiGe block may be removed to allow a second gate oxide to be formed on the surface previously occupied by the relaxed SiGe block.

  • Patent number: 7741181
    Abstract: A method for fabricating metal gate and polysilicon gate FET devices on the same chip is disclosed. The method avoids the use of two separate masks during gate stack fabrication of the differing gates. By using a single mask, tighter NFET to PFET distances can be achieved, and the fabrication process is simplified. After blanket disposing layers for the fabrication of the metal gate stack, a covering protective material layer is formed, again in blanket fashion. A block level mask is used to clear the surface for the gate insulator formation in the poly gate device regions. During oxidation, which forms the gate dielectric for the poly gate devices, the protective material prevents damage of the metal gate device regions. Following oxidation, a single common polysilicon cover is disposed in blanket manner for continuing the fabrication of the gate stacks. The protective material is selected in such a way to be either easily removable upon oxidation, or to be conductive upon oxidation.

  • Publication number: 20100150513
    Abstract: A multifunctional optical film for enhancing light extraction includes a flexible substrate, a structured layer having nanoparticles of different sizes, and a backfill layer. The structured layer effectively uses microreplicated diffractive or scattering nanostructures located near enough to the light generation region to enable extraction of an evanescent wave from an organic light emitting diode (OLED) device. The backfill layer has a material having an index of refraction different from the index of refraction of the structured layer. The backfill layer also provides a planarizing layer over the structured layer in order to conform the light extraction film to a layer of an OLED display device. The film may have additional layers added to or incorporated within it to an emissive surface in order to effect additional functionalities beyond improvement of light extraction efficiency.

  • Publication number: 20100112800
    Abstract: Methods for fabricating a CMOS structure use a first gate stack located over a first orientation region of a semiconductor substrate. A second gate material layer is located over the first gate stack and a laterally adjacent second orientation region of the semiconductor substrate. A planarizing layer is located upon the second gate material layer. The planarizing layer and the second gate material layer are non-selectively etched to form a second gate stack that approximates the height of the first gate stack. An etch stop layer may also be formed upon the first gate stack. The resulting CMOS structure may comprise different gate dielectrics, metal gates and silicon gates.
