  • Publication number: 20130228735
    Abstract: A nonvolatile resistive memory element includes a host oxide formed from an interfacial oxide layer. The interfacial oxide layer is formed on the surface of a deposited electrode layer via in situ or post-deposition surface oxidation treatments. The switching performance of a resistive memory device based on such an interfacial oxide layer is equivalent or superior to the performance of a conventional resistive memory element.

  • Patent number: 8415256
    Abstract: During semiconductor fabrication homogeneous gap-filling is achieved by depositing a thin dielectric layer into the gap, post deposition curing, and then repeating deposition and post deposition curing until gap-filling is completed. Embodiments include depositing a layer of low deposition temperature gap-fill dielectric into a high aspect ratio opening, such as a shallow trench or a gap between closely spaced apart gate electrode structures, as at a thickness of about 10 ? to about 500 ?, curing after deposition, as by UV radiation or by heating at a temperature of about 400° C. to about 1000° C., depositing another layer of low deposition temperature gap-filled dielectric, and curing after deposition. Embodiments include separately depositing and separately curing multiple layers.

  • Patent number: 8026169
    Abstract: Data retention in flash memory devices, such as mirrorbit devices, is improved by reducing the generation and/or diffusion of hydrogen ions during back end processing, such as annealing inlaid Cu. Embodiments include annealing inlaid Cu in an N2 atmosphere containing low H2 or no H2, and at temperatures less than 200° C., e.g., 100° C. to 150° C.

  • Patent number: 7534732
    Abstract: Cu interconnects are formed with composite capping layers for reduced electromigration, improved adhesion between Cu and the capping layer, and reduced charge loss in associated non-volatile transistors. Embodiments include depositing a first relatively thin silicon nitride layer having a relatively high concentration of Si—H bonds on the upper surface of a layer of Cu for improved adhesion and reduced electromigration, and depositing a second relatively thick silicon nitride layer having a relatively low concentration of Si—H bonds on the first silicon nitride layer for reduced charge loss.

  • Publication number: 20080096364
    Abstract: Gap filling between features which are closely spaced is significantly improved by initially depositing a thin conformal layer followed by depositing a layer of gap filling dielectric material. Embodiments include depositing a thin conformal layer of silicon nitride or silicon oxide, as by atomic layer deposition or pulsed layer deposition, into the gap between adjacent gate electrode structures such that it flows into undercut regions of dielectric spacers on side surfaces of the gate electrode structures, and then depositing a layer of BPSG or P-HDP oxide on the thin conformal layer into the gap. Embodiments further include depositing the layers at a temperature less than 430° C., as by depositing a P-HDP oxide after depositing the conformal liner when the gate electrode structures include a layer of nickel silicide.

  • Publication number: 20060046502
    Abstract: For forming an IC (integrated circuit) structure over a conductive surface, a hard-mask is deposited on the conductive surface with a low temperature in a range of from about 220° Celsius to about 320° Celsius for minimized formation of hillocks. Generally, formation of hillocks and bubbles from deposition of the hard-mask are minimized on the conductive surface. The hard-mask is etched away from the conductive surface, and the IC structure is formed over the conductive surface after the hard-mask is etched away.

  • Patent number: 6875694
    Abstract: An exposed surface of inlaid Cu is plasma treated for improved capping layer adhesion while controlling plasma conditions to avoid damaging porous low-k materials. Embodiments include forming a dual damascene opening in a porous dielectric material having a dielectric constant (k) of up to 2.4, e.g., 2.0 to 2.2, filling the opening with Cu, conducting CMP, plasma treating the exposed Cu surface in NH3 or H2 at a low power, e.g., 75 to 125 watts, for a short period of time, e.g., 2 to 8 seconds, without etching the porous low-k material and depositing a capping layer, e.g., silicon nitride or silicon carbide.

  • Publication number: 20050006693
    Abstract: Semiconductor devices with improved data retention are formed by depositing an undoped oxide liner on spaced apart transistors followed by in situ deposition of a BPSG layer. Embodiments include depositing an undoped silicon oxide liner derived from TEOS, as at a thickness of 400 ? to 600 ?, on transistors of a non-volatile semiconductor device, as by sub-atmospheric chemical vapor deposition, followed by depositing the BPSG layer in the same deposition chamber.

  • Patent number: 6235654
    Abstract: A process for very low deposition rate plasma-enhanced chemical vapor deposition (PECVD) of nitride is provided. A nitride layer is used, for example, as a precursor for nitride spacers formed on the sidewalls of a polysilicon gate. The nitride layer may be produced in a PECVD chamber, using an increased flow rate of nitrogen applied to the chamber, an increased flow rate of molecular nitrogen, and a reduced flow rate of ammonia. The RF power is reduced, as well as the reactor pressure. This produces a nitride layer that exhibits improvements in density, refractive index, step coverage, and thickness non-unformity within a wafer and from wafer-to-wafer.
