| Summary: | 碩士 === 長庚大學 === 電子工程學系 === 98 === The purpose of the thesis is to make the crystal oscillator for the process. It's different from the traditional quartz crystal that needs to segment and beveling. If we use the process to make the crystal oscillator, we will make the volume of an element become much smaller than before. In addition, we also can achieve the goal for the better , lower cost and lower power consumption. Crystal oscillator is the standard element in communication. If you just use low power, the quartz crystal will create the oscillation of the same frequency. Most important of all, the change of the sealed temperature doesn't have a great effect upon the frequency of crystal oscillator is a kind of a material of piezoelectricity for people to get it easily. By the precise segment and beveling, we can make the crystal oscillator maintain the frequency. The thesis is mainly aimed at this aspect for me to make a research.
