    摘要: A method of replacing a top oxide around a storage element of a memory device is provided. The method can involve removing a core first poly and core first top oxide in a core region while not removing a periphery first poly in a periphery region on a semiconductor substrate; forming a second top oxide around a storage element in the core region and on the periphery first poly in the periphery region; forming a second poly over the semiconductor substrate in both the core and periphery regions; removing the second poly and second top oxide in the periphery region; and forming a third poly on the semiconductor substrate in both the core and periphery regions.

    摘要: Methods of forming a memory cell containing two split sub-lithographic charge storage nodes on a semiconductor substrate are provided. The methods can involve forming two split sub-lithographic charge storage nodes by using spacer formation techniques. By removing exposed portions of a first poly layer while leaving portions of the first poly layer protected by the spacers, the method can provide two split sub-lithographic first poly gates. Further, by removing exposed portions of a charge storage layer while leaving portions of the charge storage layer protected by the two split sub-lithographic first poly gates, the method can provide two split, narrow portions of the charge storage layer, which subsequently form two split sub-lithographic charge storage nodes.

    摘要: Methods and systems for generating masks for spacer formation are disclosed. As a part of a disclosed method, a predefined final wafer pattern is accessed, areas related to features in the predefined final wafer pattern are identified and a template mask is formed based on the identified areas for forming spacers on a wafer. Subsequently, a mask is formed for use in the removal of portions of the spacers to form an on wafer pattern that corresponds to the predefined final wafer pattern.

    摘要: A method of forming a metal gate in a wafer. PolySi1-xGex and polysilicon are used to form a tapered groove. Gate oxide, PolySi1-xGex, and polysilicon is deposited on a wafer. A resist pattern is formed. A portion of the polysilicon, PolySi1-xGex, and gate oxide is removed to provide a tapered profile. The resist is removed; a dielectric liner is deposited, and then at least a portion of the dielectric liner is removed, thereby exposing the polysilicon and leaving the dielectric liner in contact with the polysilicon, PolySi1-xGex, and gate oxide. A dielectric is deposited, and a portion is removed thereby exposing the polysilicon. The polysilicon, PolySi1-xGex, and gate oxide is removed from inside the dielectric liner, thereby leaving a tapered gate groove. Metal is then deposited in the groove.
