    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： 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 Å to about 500 Å, 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.

    摘要： Flash memory devices and methods for fabricating the same are provided. A method for fabricating a memory device comprises the steps of fabricating a first gate stack and a second gate stack overlying a P-type silicon substrate and implanting an impurity dopant into the substrate substantially between the first gate stack and the second gate stack to form an impurity-doped region of the substrate. A channel region underlies the first gate stack adjacent to the impurity-doped region. An intrinsically tensile-stressed insulating member is formed between the first and the second gate stacks and overlying the impurity-doped region. The tensile-stressed insulating member causes a uniaxial lateral tensile stress to be transmitted to the first channel region. A word line is formed overlying the intrinsically tensile-stressed insulating member and in electrical contact with the first gate stack and the second gate stack.
