Cu hillock成因
WebApr 30, 2004 · When Cu wafers are exposed to plasma, hillocks are formed on the Cu wafer surface by a plasma cleaner with a surface wave plasma source. Plasma cleaning is divided into the initial stage and the rising temperature stage.

WebA new failure mode in AlCu and AlCuSi metallization is described in which interlevel metal short circuiting occurs between two or more levels of metal. Shorts are caused by theta-phase (Al/sub 2/Cu) hillocks which nucleate and grow during high-temperature vacuum … WebDec 15, 1995 · The addition of Cu to pure Al significantly decreased the hillock density, but the addition of W to AlCu films increased the hillock density. Indeed, no hillocks were observed in AlCu films. However, there was an abundance ofAIzCu pre- cipitates on the annealed AlCu wafers. For this reason, the hillock densities of AlCu films are not …
WebTable 1 represents hillock counts measured on copper test samples, where the copper samples were subjected to a pre-CVD annealing process under a 95/5 N 2 /H 2 blanket for a period of about 180 seconds. As can be seen from the representative data in Table 1, low temperature annealing of copper samples at between 200° C. and 260° C. resulted ... WebJan 1, 2024 · The SEM images of the Cu-Mo-Ag, Fig. 3 (a–c), display hillock formation only for the 600 and 800 °C films. The 400 °C film surface was flat and smooth save a few sample preparation scratches. Both the 600 and 800 °C films contained a high density of hillocks evenly distributed throughout the surface with similar hillock morphology as Cu-Ta.
Webwould cause Cu hillock issue, which influence the Stress-Migration performance or induce other integration problems. Similarly, the bulk silicon nitride film property is also important for Cu dual-damascene process. Silicon nitride film would influence Cu diffusion barriers ability, via profile, via resistance and electron-migration
