    Abstract: Container structures for use in integrated circuits and methods of their manufacture without the use of mechanical planarization such as chemical-mechanical planarization (CMP), thus eliminating CMP-induced defects and variations. The methods utilize localized masking of holes for protection of the inside of the holes during non-mechanical removal of exposed surface layers. The localized masking is accomplished through differential exposure of a resist layer to electromagnetic or thermal energy. The container structures are adapted for use in memory cells and apparatus incorporating such memory cells, as well as other integrated circuits.

    Abstract: A capacitor fabrication method may include atomic layer depositing a conductive barrier layer to oxygen diffusion over the first electrode. A method may instead include chemisorbing a layer of a first precursor at least one monolayer thick over the first electrode and chemisorbing a layer of a second precursor at least one monolayer thick on the first precursor layer, a chemisorption product of the first and second precursor layers being comprised by a layer of a conductive barrier material. The barrier layer may be sufficiently thick and dense to reduce oxidation of the first electrode by oxygen diffusion from over the barrier layer. An alternative method may include forming a first capacitor electrode over a substrate, the first electrode having an inner surface area per unit area and an outer surface area per unit area that are both greater than an outer surface area per unit area of the substrate. A capacitor dielectric layer and a second capacitor electrode may be formed over the dielectric layer. The method may further include forming rugged polysilicon over the substrate, the first electrode being over the rugged polysilicon. Accordingly, the outer surface area of the first electrode can be at least 30% greater than the outer surface area of the substrate without the first electrode including polysilicon.

    Abstract: A deposition method includes forming a nucleation layer over a substrate, forming a layer of a first substance at least one monolayer thick chemisorbed on the nucleation layer, and forming a layer of a second substance at least one monolayer thick chemisorbed on the first substance. The chemisorption product of the first and second substance may include silicon and nitrogen. The nucleation layer may comprise silicon nitride. Further, a deposition method may include forming a first part of a nucleation layer on a first surface of a substrate and forming a second part of a nucleation layer on a second surface of the substrate. A deposition layer may be formed on the first and second parts of the nucleation layer substantially non-selectively on the first part of the nucleation layer compared to the second part. The first surface may be a surface of a borophosphosilicate glass layer. The second surface may be a surface of a rugged polysilicon layer. The first and second part of the nucleation layer may be formed simultaneously.

    Abstract: Semiconductor processing methods and defect detection methods are described. In one embodiment, a semiconductor wafer in process is provided and a material is formed or deposited over the wafer. The material is discernably deposited over defective wafer surface areas and not appreciably deposited over non-defective wafer surface areas. Subsequently, the wafer surface areas are inspected to identify defective areas. In another embodiment, a substrate is provided having an exposed region containing surface defects. A defect-highlighting material is substantially selectively deposited over surface defects and not appreciably over other exposed regions. The substrate is subsequently inspected for the deposited defect-highlighting material. In yet another embodiment, a dielectric layer is formed over a substrate outer surface and the substrate is processed in a manner which can give rise to a plurality of randomly-distributed dielectric layer features. A silicon-containing material is substantially selectively deposited and received over the randomly distributed dielectric layer features and not over other substrate areas. The substrate is subsequently inspected for the selectively-deposited silicon containing material.

    Abstract: An exemplary implementation of the present invention discloses a semiconductor fabrication method for forming a film in a reactor. Process conditions (temperature and pressure) are initially stabilized prior to a film deposition cycle. Once process conditions are stable, chemical elements of are nucleated onto a substrate surface to form a nucleation surface of the film. The bulk portion of the film is then deposited onto the nucleation surface. Finally, after the bulk of the film is deposited the surface of the film is conditioned. To tailor a film the process conditions are varied during the film deposition cycle wherein at least one of the pressures and temperatures is varied by at least 10%. In a specific implementation, a capacitor dielectric of silicon nitride is tailored by varying the pressure for the bulk film deposition and by varying both the temperature and pressure for the film surface formation phase.
