    • PURPOSE: A ceramic package of a multi-mode crystal oscillator is provided to improve oscillation efficiency and frequency stability by laminating high frequency and low frequency crystal oscillators in one package. CONSTITUTION: An external terminal(31T) is formed on a base layer(31). A step layer(32) is formed on a periphery of the base layer and includes an internal terminal(32T) which is electrically coupled with the external terminal. A first frequency crystal plate(33) is implemented to vibrate on the step layer at a predetermined frequency. A buffer layer(34) is spaced apart from the step layer on the base layer and includes an internal terminal(34T), wherein the internal electrode is electrically coupled with the external terminal of the base layer. A second frequency crystal plate(35) is apart from the first frequency crystal plate and is implemented to vibrate on the buffer layer. A support layer(37) is formed on the step layer. A rib(38) is covered on the support layer to seal the implementation portion of the first and second frequency crystal plates.

    • A ceramic package of a crystal oscillator is provided to prevent a short in a process by removing an existing side electrode connecting electrode patterns formed at each side of a ground layer. In a ceramic package of a crystal oscillator, electrode patterns formed at one side and the other side of a ground layer(31) are connected each other through a via hole. First and second buffer layers(32a) are formed at an upper surface of the electrode pattern formed on the one side of the ground layer(31). A crystal piece of which one side is fixed to the surface of the first and second buffer layers(32a) oscillates by an electric signal. A third buffer layer(34) is formed on a bottom of the other side of the crystal piece, on the surface of the ground layer(31). A support layer(37) formed at a surface of an edge part of the ground layer(31) forms a space unit(37) accepting the crystal piece. And, a rib covers the support layer(37) for sealing a crystal piece mounted part.
