  • Publication number: 20150170923
    Abstract: Selective wet etching is used to produce feature sizes of reduced width in semiconductor devices. An initial patterning step (e.g., photolithography) forms a pillar of an initial width from at least a selected first layer and an overlayer. A wet etchant that is selective to the selected layer undercuts the sidewalls of the selected layer to a smaller width while leaving at least part of the overlayer in place to protect the top surface of the selected layer. The selected layer becomes a narrow “stem” within the pillar, and may have dimensions below the resolution limit of the technique used for the initial patterning. For some devices, voids may be intentionally left in a fill layer around the stem for electrical or thermal insulation.

  • Patent number: 9018037
    Abstract: Forming a resistive switching layer having a vertical interface can generate defects confined along the interface between two electrodes. The confined defects can form a pre-determined region for filament formation and dissolution, leading to low power resistive switching and low program voltage or current variability. In addition, the filament forming process of the resistive memory device can be omitted due to the existence of the confined defects.

  • Publication number: 20140154859
    Abstract: Provided are methods for processing different materials on the same substrate for high throughput screening of multiple ReRAM materials. A substrate may be divided into multiple site isolated regions, each region including one or more base structures operable as bottom electrodes of ReRAM cells. Different test samples may be formed over these base structures in a combinatorial manner. Specifically, each site isolated region may receive a test sample that has a different characteristic than at least one other sample provided in another region. The test samples may have different compositions and/or thicknesses or be deposited using different techniques. These different samples are then etched in the same operation to form portions of the samples. Each portion is substantially larger than the corresponding base structure and fully covers this base structure to protect the interface between the base structure and the portion during etching.

  • 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.
