High-entropy ceramics exhibit novel intrinsic properties. Hence, they have been explored for a wide range of applications ranging from thermal insulation and energy storage to advanced optical components. Recently, the semiconductor industry has faced a demand for higher-performance chips, necessitating higher aspect ratios in wafer fabrication and further miniaturization of linewidths. Therefore, novel materials with high plasma etching resistance and minimal contaminant generation are needed. The plasma-etching resistance displayed by high-entropy ceramics can be an innovative solution to this emerging challenge. In this study, we successfully fabricated single-phase high-entropy sesquioxide ceramics with high optical transparency, dense microstructure, and minimal residual pores. A structural analysis of the fabricated samples revealed a single-phase structure with excellent phase homogeneity. An evaluation of the plasma-etching resistance of high-entropy ceramics revealed for the first time a low etching rate of 8 nm/h compared with that of conventional plasma-resistant materials. These comprehensive characterizations of high-entropy ceramics indicate that they are promising candidates for significantly improving the production yield of semiconductors and for a wide range of potential applications, such as next-generation active optical ceramics.

A FRAMEWORK OF SETTING UP GOAL CONTROL LIMITS OF TARGET COSTING FOR NON-NORMAL DISTRIBUTIONS

引用

Journal of Systems Science and Systems Engineering 2007年第4期16卷 424-433页

作者： Hsin-Hung WU Fong-jung yu Department of Business Administration National Changhua University of Education Changhua Taiwan China Department of Industrial Engineering and Technology Management Da-Yeh University Changhua Taiwan China

This study provides a framework of target costing to extend its original scope when the underlying distribution is non-normal. The new specification limits can be derived by listening to the market price from Taguchi loss function. Later, the new specification limits can be linked through the non-normality-based C^^pk value along with non-normality-based X^^-Rcontrol charts to derive goal control limits. Moreover, an example is provided to illustrate the usefulness of the proposed framework of target costing by relentlessly reducing cost and improving product quality to gain competitiveness in the marketplace.

Characterization of solid particles sampled from condensates in boiling water reactor

Nuclear Science and Techniques 2016年第2期27卷 141-148页

作者： yu-Hung Shih tung-Jen Wen Liang-Cheng Chen Tsuey-Lin Tsai Chemistry Division Institute of Nuclear Energy Research

The growth, activation and deposition of corrosion products are the primary sources of radiation buildup on the surface of out-of-core piping in nuclear power plants. The buildup of radiation can have negative effects on the performance of the facility and cause harm to staff during maintenance outages for refueling. This paper reports on the crystalline and amorphous structures of corrosion products sampled in the boiling water reactors in nuclear power plants of Kuo-Sheng and identified using an acid dissolving technique. X-ray diffraction, scanning electron microprobe and inductively coupled plasmaatomic emission spectroscopy were used to analyze the samples. The results indicate that the quantity of amorphous iron oxide at inlet of the condensate demineralizer in Unit 2 is higher than that in Unit 1. The proportion of crystalline to amorphous corrosion products can affect the efficiency of removal. Thus, these results can be used to explain the difference in removal efficiency of condensate demineralizers in different units. Moreover, the iron oxide structures with various properties were observed in different operational periods. It is probable that the higher proportion of amorphous structures with a smaller particle size would reduce efficiency in the removal of condensate demineralization in Unit 2.
