    摘要: A method of manufacturing for a Flash memory includes depositing a charge-trapping material over a semiconductor substrate and implanting first and second bitlines. A wordline material is deposited over the charge-trapping dielectric material and a hard mask material deposited. A disposable anti-reflective coating (ARC) material and a photoresist material are deposited followed by processing to form a patterned photoresist material and a patterned ARC material. The hard mask material is processed to form a patterned hard mask material. The patterned photoresist is removed and then the patterned ARC without damaging the patterned hard mask material or the wordline material. The wordline material is processed using the patterned hard mask material to form a wordline and the patterned hard mask material is removed without damaging the wordline or the charge-trapping dielectric material.

    摘要: A method of forming spaces between polysilicon lines can include patterning structures having top SiON layers and bottom amorphous carbon layers where the structures are located over a polysilicon layer and are separated by a first width, forming amorphous carbon spacers along lateral side walls of the patterned structures, etching apertures into the polysilicon layer not covered by the amorphous carbon spacers and the patterned structures where the apertures in the polysilicon layer between adjacent patterned structures have a second width, and ashing away the amorphous carbon spacers and the patterned structures. The second width is less than the first width.

    摘要: Photoresist mask width dimensions are measured by detecting a reflected light during etching or depositing material on the sidewalls of the photoresist mask in a plasma chamber having an etchant mixture. Embodiments include determining the time to stop the etching of the photoresist mask by detecting a corresponding change in the intensity of the reflected light.

    摘要: An improved method of forming circuit structures having linewidths which are smaller than what is achievable by conventional UV lithographic techniques on ultra-thin resist layers is provided. The method includes a hardmask which is patterned using an ultra-thin resist layer and is then trimmed to reduce the width of the hardmask before etching the underlying gate conductive layer.

    摘要: An exemplary embodiment relates to a method of pinhole decoration and detection. The method can include providing a material layer above an amorphous carbon layer where the material layer has a pinhole, providing a film over the material layer where the film has a substantially planar surface except above the pinhole, and detecting the pinhole by detecting a non-planar location on the substantially planar surface of the film.

    摘要: A gate is formed by depositing a gate conductive layer over a substrate layer, depositing an organic spin-on bottom anti-reflective coating (BARC) over the gate conductive layer, and forming a resist mask on the BARC. Next, the resist mask is controllably etched to further reduce the critical dimensions of gate pattern formed therein, and then the gate is formed by etching the gate conductive layer using the reduced size resist mask.
