초록
Advancement of semiconductor technology, introduction of 5G networks, and expansion of the electric vehicle market havegradually increased the demand for highly reliable multilayer ceramic capacitors (MLCCs) owing to requirement of miniatureelectronic equipment. Efforts to achieve high reliability are underway to improve the properties of materials such as dielectrics,internal electrodes, and external electrodes. However, there are few studies on appropriate measurement methods forevaluating reliability, deterioration mechanisms, and lifetime calculations. In this study, an MLCC device was made todeteriorate through the highly accelerated life test (HALT), and the capacitance–voltage (C–V), temperature coefficient ofcapacitance (TCC), and current–voltage (I–V) characteristics were analyzed according to the elapsed time of deterioration. Inaddition, the activation energy (Ea) and voltage acceleration coefficient (n) were extracted through a lifetime predictionexperiment, and the results of failure in time (FIT) and mean time to failure (MTTF) indicated the lifetime of the MLCC. From the results, it was confirmed that the insulation resistance evaluated using the HALT is an important factor forconfirming the reliability and lifetime characteristics of MLCCs.
Abstract
Advancement of semiconductor technology, introduction of 5G networks, and expansion of the electric vehicle market havegradually increased the demand for highly reliable multilayer ceramic capacitors (MLCCs) owing to requirement of miniatureelectronic equipment. Efforts to achieve high reliability are underway to improve the properties of materials such as dielectrics,internal electrodes, and external electrodes. However, there are few studies on appropriate measurement methods forevaluating reliability, deterioration mechanisms, and lifetime calculations. In this study, an MLCC device was made todeteriorate through the highly accelerated life test (HALT), and the capacitance–voltage (C–V), temperature coefficient ofcapacitance (TCC), and current–voltage (I–V) characteristics were analyzed according to the elapsed time of deterioration. Inaddition, the activation energy (Ea) and voltage acceleration coefficient (n) were extracted through a lifetime predictionexperiment, and the results of failure in time (FIT) and mean time to failure (MTTF) indicated the lifetime of the MLCC. From the results, it was confirmed that the insulation resistance evaluated using the HALT is an important factor forconfirming the reliability and lifetime characteristics of MLCCs.
