... resistance (R) can be reduced from 6.5–8.2 K ⋅ m ⋅ W −1 to 0.004–0.013 K ⋅ m ⋅ W −1 . The improvement is far superior to existing studies. Besides, decreasing the surface roughness and increasing contact pressure also help to reduce R, especially for the cases when the LMTA is not melted. As the LMTA melts...

...K. N. Prabhu; G. Kumar The effects of substrate material, substrate surface roughness, and operating temperature on the wetting behavior of Sn–37Pb, Sn–3.5Ag, and Sn–9Zn eutectic solders on metallic substrates were investigated. Solder spreading kinetics was successfully represented...

... on the surface roughness. Accordingly, these two methods can provide not only a (biaxial) stress field similar to temperature-loaded die in the packages, but also simple, feasible, reliable, and chipping-free tests for silicon dies of dummy or real IC chips, without strict geometrical limitation, such as beam...

... occurs at the location near the rim of the heat spreader. The effect of surface roughness on both local and average natural convective heat transfer behaviors from nominally flat silicon-based spreader surfaces to the external ambient is not significant. Two new generalized correlations of local...

...Xiang-Qi Wang; Christopher Yap; Arun Sadashiv Mujumdar The friction factors of single-phase microchannel with various roughness elements (rectangular, triangular, elliptical) were investigated numerically. The two-dimensional numerical solution shows significant influence of surface roughness...

... ° C ) , and combinations of these two methods were examined to investigate the wafer cleaning effect. When wafers were cleaned by RCA after SPM cleaning, maximal bonding quality at room temperature was gained. Surface roughness, as measured by AFM (atomic force microscope), was found to correspond...

...Neil McLellan; Nelson Fan; Shilai Liu; Kim Lau; Jingshen Wu A systematic investigation on the effects of wafer thinning process on the surface roughness, morphology and fracture strength of silicon chips was conducted. The results of the study suggest that the fracture strength of the silicon chips...
