584 Multilayer ceramic capacitors Yukio Sakabe Significant advances have been achieved in the manufacturing Figure 1 technology of high volumetric multilayer ceramic capacitors (MLCs) comprised of hundreds of dielectric layers less than 31im in thickness. A capacitor consists of a BaTi03-based X7R ceramic and nickel internal electrodes.
As many as 300 multilayer ceramic chip capacitors are used in a typical mobile phone, and more than a thousand in a PC or game console. It is fair to say that the downsizing and weight reduction of mobile devices and other electronic products would have been impossible without the miniaturization of multilayer ceramic chip capacitors.
The primary benefit of multilayer ceramic chip capacitors is their ability to provide high capacitance in small dimensions, achieved by stacking a large number of electrodes. In the early 1980s, a chip capacitor in the “3216” form factor (3.2 by 1.6 mm) had a capacitance of 0.1 µF, but that figure has reached 100 µF today—a thousand-fold increase.

Local electric-field around multitype pores (dielectric pore, interface pore, electrode pore) in multilayer ceramic capacitors (MLCCs) was investigated using Kelvin probe force microscopy combined with the finite element simulation to understand the effect of pores on the electric reliability of MLCCs.
Multilayer ceramic chip capacitors are sintered at temperatures ranging from around 1,000 to 1,300°C. Sintering in an ordinary atmosphere results in oxidation of the internal electrodes; yet, sintering in a reductive atmosphere with little oxygen reduces the dielectric into a semiconductor, deteriorating the capacitor’s characteristics.
