    摘要： A temperature sensing apparatus and method are described to detect a change in a frequency due to a change in a temperature. An infrared light sensing apparatus and method are also provided. The temperature sensing apparatus may include an electrode to generate an electrical signal, a piezoelectric layer to convert the electrical signal into an acoustic wave, and a temperature sensitive layer formed by doping impurities in one or more structures formed on a substrate. Additionally, the infrared light sensing apparatus may convert into heat infrared light incident to an infrared light absorption layer, using an infrared light reflection layer and the infrared light absorption layer. A temperature sensitive layer may detect a change in a resonant frequency based on a change in a temperature of the heat, and may detect a change in infrared light based on the change in the resonant frequency.

    摘要： A Bulk Acoustic Wave Resonator (BAWR), a method of manufacturing of the BAWR, and duplexer including the BAWR are provided. The BAWR may include a first substrate including a via hole formed in a predetermined area of a bottom surface of the first substrate. A first air cavity may be formed above the first substrate, and a first lamination resonating portion may be laminated above the first air cavity in sequence of a lower electrode, a piezoelectric layer, and an upper electrode. A second air cavity may be formed above the first substrate, and a second lamination resonating portion may be laminated above the second air cavity in sequence of the lower electrode, the piezoelectric layer, and the upper electrode. The first lamination resonating portion and the second lamination resonating portion may be connected via either the lower electrode or the upper electrode. A first electrode portion may include a third air cavity formed on a bottom surface of either the lower electrode or the upper electrode connecting between the first lamination resonating portion and the second lamination resonating portion.
