A method of manufacturing high reliability quartz crystal oscillators and a quartz crystal oscillator produced therefrom is disclosed. In the present invention, a quartz crystal oscillating plate is mounted to a ceramic base within the top cavity of the ceramic base by means of a plurality of metal bumps. The quartz crystal oscillator has a ceramic base formed by laminating a second ceramic layer along the periphery of the top surface of a first ceramic layer. The ceramic base has a top cavity, with a plurality of electrode terminals formed on the first ceramic layer at predetermined positions and electrically connected to external electrodes. A quartz crystal oscillating plate, having a plurality of electrode patterns, is mounted to the electrode terminals of the first ceramic base within the top cavity through a plurality of metal bumps such that a remaining part of the oscillating plate except for the terminals is spaced apart from the ceramic base by a gap. A ceramic lid covers the top of the top cavity of the ceramic base, thus sealing the oscillating plate. |
