Abstract
Silicon (Si) has a high theoretical capacity and low working potential vs. Li/Li
+
, and has been investigated as the most capable negative electrode material for lithium-ion batteries (LIBs). However, Si undergoes significant volume changes during the Li
+
alloying/ dealloying processes, leading to unstable cycle life and limiting its practical applicability.....

DOI:
https://doi.org/10.3365/KJMM.2019.57.11.689
Abstract
This article details how effectively dicing damage of silicon wafers can be mechanically minimized by appropriate laser-induced groove formation prior to wafer separation. Various laser dicing factors, such as the laser-control power, the scan rate and the scan number of the laser beam, were estimated to determine the optimum groove.....

Abstract
In micro/nano electro-mechanical system, silicon nitride (SiNx) membrane has been widely used in sensors, energy harvesting and optical filters because of its mechanical/chemical stability. However, it is necessary to verify mechanical and thermal properties of nanoscale SiNx membranes to ensure the desirable reliability and durability of a device because the.....

Abstract
Both the mechanical properties and probability distribution of liquid phase sintered SiC (LPS-SiC) materials were investigated, based on a detailed analysis of their microstructures. In particular, the effect of the starting sizes of SiC particles on the characterization of LPS-SiC materials was evaluated. LPS-SiC materials were fabricated with a constant.....

Abstract
In this study, the extrusion behavior of Cu fill material in a through-Si-via (TSV) subjected to thermal loading was investigated. The Cu filling of the TSV was accomplished using pulse periodic reverse (PPR) electroplating. To study the extrusion, TSVs of varying via pitch were filled with Cu by electroplating. Defect-free Cu.....

Abstract
Aluminum-induced crystallization(AIC) is one of the ways to improve characteristics of thin-film poly-crystalline (TFPC) silicon solar cell since it shows large grain size and good properties for TFPC silicon solar cell. In AIC process, aluminum is firstly deposited on foreign substrate. Then, silicon is deposited on aluminum. Annealing was done.....

Abstract
The silicon microlens is a key element in advanced optical packaging. However, the difficulty of its fabrication process and low yield have hindered the development of an silicon lens based optical device module. A silicon Fresnel lens was studied using ray tracing optical simulation, because its small sagittal height allows.....

Abstract
This work details how the sawing velocity influences the chipping damage of semiconductor wafers with different thicknesses during wafer separation. The experimental result shows that at a sawing velocity higher than 60000 rpm, in thinner wafers the magnitude of chipping damage more strongly depends on the revolving velocity of the.....
