Patent number: 8637918Abstract: A memory and method of manufacture employing word line scaling. A layered stack, including a charge trapping component and a core polysilicon layer, is formed on a core section and a peripheral section of a substrate. A portion of the layered stack, including the core polysilicon layer is then removed from the peripheral section. A peripheral polysilicon layer, which is thicker than the core polysilicon layer of the layered stack, is next formed on the layered stack and the peripheral section. The layered stack is then isolated from the peripheral polysilicon layer by removing a portion of the peripheral polysilicon layer from the core section, and polysilicon lines are patterned in the isolated layered stack.Type: GrantFiled: November 10, 2011Date of Patent: January 28, 2014Assignee: Spansion LLCInventors: Shenqing Fang, Chun Chen, Wenmei Li, Inkuk Kang, Gang Xue, Hyesook Hong

Patent number: 7129162Abstract: Damascene methods for forming copper conductors (30, 130) are disclosed. According to the disclosed method, a dual cap layer (18, 20; 122, 124) is formed over an organosilicate glass insulating layer (16; 116, 120) prior to the etching of a via or trench toward an underlying conductor (12; 112). The dual cap layer includes a layer of silicon carbide (18; 124) and a layer of silicon nitride (20; 122). The silicon carbide layer (18; 124) and silicon nitride layer (20; 122) can be deposited in either order relative to one another. The silicon carbide layer (18; 124) maintains the critical dimension of the via or trench as it is etched through the insulating layer (16; 116, 120), while the silicon nitride layer (20; 122) inhibits the failure mechanism of resist poisoning. The method is applicable to single damascene processes, but may also be used in dual damascene copper processes.Type: GrantFiled: May 2, 2003Date of Patent: October 31, 2006Assignee: Texas Instruments IncorporatedInventors: Hyesook Hong, Guoqiang Xing, Ping Jiang

Patent number: 6620560Abstract: Plasma treating a low-k dielectric layer (104) using an oxidation reaction (e.g., O2) to improve patterning. Resist poisoning occurs due to an interaction between low-k films (104), such as OSG, and DUV resist (130, 132). The plasma treatment is performed to either pretreat a low-k dielectric (104) before forming the pattern (130, 132), during a rework of the pattern (130, 132), or between via and trench patterning to reduce resist poisoning.Type: GrantFiled: October 11, 2001Date of Patent: September 16, 2003Assignee: Texax Instruments IncorporatedInventors: Ping Jiang, Guoqiang Xing, Andrew J.
