  • Patent number: 10068802
    Abstract: An integrated circuit containing MOS transistors may be formed using a split carbon co-implantation. The split carbon co-implant includes an angled carbon implant and a zero-degree carbon implant that is substantially perpendicular to a top surface of the integrated circuit. The split carbon co-implant is done at the LDD and halo implant steps.

  • Publication number: 20180012280
    Abstract: In some embodiments, systems are provided to enable a consumer to search the inventory of an enable a consumer to search the inventory of a plurality of unaffiliated brick-and-mortar retail entities to facilitate purchase opportunities. The system may include electronic user devices comprising a search interface stored thereon. Databases can be communicatively coupled to a plurality of unaffiliated brick-and-mortar retail entities and configured to store inventory transaction data points received from unaffiliated brick-and-mortar retail entities. Each inventory transaction data point can correspond to descriptive characteristics of a first inventory item. Search requests for second inventory items can be received from search interfaces. Inventory transaction data points that correspond to first inventory items that each share a threshold number of descriptive characteristics with some second inventory items.

  • Patent number: 9431533
    Abstract: An integrated circuit containing an NMOS transistor with a boron-doped halo is formed by co-implanting carbon in at least three angled doses with the boron halo implants. The carbon is co-implanted at tilt angles within 5 degrees of the boron halo implant tilt angle. An implant energy of at least one of the angled carbon co-implant is greater than the implant energy of the boron halo implant. A total carbon dose of the angled carbon co-implants is at least 5 times a total boron dose of the boron halo implants. The NMOS transistor has a carbon concentration in the halo regions which is at least 5 times greater than the boron concentration in the halo regions. The co-implanted carbon extends under the gate of the NMOS transistor.

  • Patent number: 9406769
    Abstract: An integrated circuit includes a PMOS gate structure and a gate structure on adjacent field oxide. An epitaxy hard mask is formed over the gate structure on the field oxide so that the epitaxy hard mask overlaps the semiconductor material in PMOS source/drain region. SiGe semiconductor material is epitaxially formed in the source/drain regions, so that that a top edge of the SiGe semiconductor material at the field oxide does not extend more than one third of a depth of the SiGe in the source/drain region abutting the field oxide. Dielectric spacers on lateral surfaces of the gate structure on the field oxide extend onto the SiGe; at least one third of the SiGe is exposed. Metal silicide covers at least one third of a top surface of the SiGe. A contact has at least half of a bottom of the contact directly contacts the metal silicide on the SiGe.

  • Publication number: 20160126108
    Abstract: In a MOS device, gate leakage is reduced by implanting gate oxide leakage reduction species such as nitrogen into the gate oxide along the edges of the gate to reduce gate leakage and hence reduce data retention fails in SRAM devices and allow low Vdd SRAM operation without increasing gate oxide thickness. By implanting nitrogen along the edges of the gate it simultaneously replaces lost gate oxide nitrogen to further reduce gate leakage.

  • Publication number: 20160118269
    Abstract: A method of gate slot etching for a memory device. Gate electrode lines are formed from a layer of gate electrode material oriented in a first direction using a first exposure and first etch process. Slots are formed oriented in a second direction orthogonal to the first direction in the gate electrode lines using a second exposure and second etch process, where the second etch process includes a bounded overetch amount (BOA) that sets a physical slot width that is bounded (bounded slot width). The BOA is determined by actual electrical test data obtained from the memory device including identifying a lower overetch amount which is <the BOA from a first electrical failure mode associated with the physical slot width being too short, and identifying an upper overetch amount which is >the BOA from a second electrical failure mode associated with the physical slot width being too long.

  • Patent number: 9224653
    Abstract: In an integrated circuit that includes an NMOS logic transistor, an NMOS SRAM transistor, and a resistor, the gate of the SRAM transistor is doped at the same time that the resistor is doped, thereby allowing the gate of the logic transistor to be separately doped without requiring any additional masking steps.

  • Patent number: 7439151
    Abstract: A method for integrating the formation of metal-insulator-metal (MIM) capacitors within dual damascene processing includes forming a lower interlevel dielectric (ILD) layer having a lower capacitor electrode and one or more lower metal lines therein, the ILD layer having a first dielectric capping layer formed thereon. An upper ILD layer is formed over the lower ILD layer, and a via and upper line structure are defined within the upper ILD layer. The via and upper line structure are filled with a planarizing layer, followed by forming and patterning a resist layer over the planarizing layer. An upper capacitor electrode structure is defined in the upper ILD layer corresponding to a removed portion of the resist. The via, upper line structure and upper capacitor electrode structure are filled with conductive material, wherein a MIM capacitor is defined by the lower capacitor electrode, first dielectric capping layer and upper capacitor electrode structure.
