A zener diode and methods for fabricating and packaging same are disclosed, whereby contact hole forming process exposing a diffusion layer is removed to enable to simplify the fabricating process, and the diffusion length not contacting the electrode line is determined by the crosswise length toward which the impurity is diffused to enable to reduce the zener impedance value. Furthermore, wet etching is used following the diffusion to remove the diffusion masks such that no damage is given to the diffusion layers to thereby enable to improve the zener diode characteristics.
