    摘要: A memory device having a metal nanocrystal charge storage structure and a method for its manufacture. The memory device may be manufactured by forming a first oxide layer on the semiconductor substrate, then disposing a porous dielectric layer on the oxide layer and disposing a second oxide layer on the porous dielectric layer. A layer of electrically conductive material is formed on the second layer of dielectric material. An etch mask is formed on the electrically conductive material. The electrically conductive material and the underlying dielectric layers are anisotropically etched to form a dielectric structure on which a gate electrode is disposed. A metal layer is formed on the dielectric structure and the gate electrode and treated so that portions of the metal layer diffuse into the porous dielectric layer. Then the metal layer is removed.

    摘要: A method for manufacturing a memory device having a metal nanocrystal charge storage structure. A substrate is provided and a first layer of dielectric material is grown on the substrate. A layer of metal oxide having a first heat of formation is formed on the first layer of dielectric material. A metal layer having a second heat of formation is formed on the metal oxide layer. The second heat of formation is greater than the first heat of formation. The metal oxide layer and the metal layer are annealed which causes the metal layer to reduce the metal oxide layer to metallic form, which then agglomerates to form metal islands. The metal layer becomes oxidized thereby embedding the metal islands within an oxide layer to form a nanocrystal layer. A control oxide is formed over the nanocrystal layer and a gate electrode is formed on the control oxide.

    摘要: 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.

    摘要: In forming an opening or space in a substrate, a layer of photoresist is provided on the substrate, and the photoresist is patterned to provide photoresist bodies having respective adjacent sidewalls. A polymer layer is provided on the resulting structure through a low temperature conformal CVD process. The polymer layer is anisotropically etched to form spacers on the respective adjacent sidewalls of the photoresist bodies. The substrate is then etched using the spacers as a mask.

    摘要: A method of forming a metal or metal nitride layer interface between a copper layer and a silicon nitride layer can include providing a metal organic gas or metal/metal nitride precursor over a copper layer, forming a metal or metal nitride layer from reactions between the metal organic gas or metal/metal nitride precursor and the copper layer, and depositing a silicon nitride layer over the metal or metal nitride layer and copper layer. The metal or metal nitride layer can provide a better interface adhesion between the silicon nitride layer and the copper layer. The metal layer can improve the interface between the copper layer and the silicon nitride layer, improving electromigration reliability and, thus, integrated circuit device performance.
