A light emitting device package capable of emitting uniform white light and a method for manufacturing the same are disclosed. The light emitting device package includes a package body, an electrode formed on at least one surface of the package body, a light emitting device mounted on the package body, and a phosphor layer enclosing the light emitting device while having a uniform thickness around the light emitting device.

Light emitting device package and method for manufacturing the same

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.

Zener diode and methods for fabricating and packaging same

Etching method applicable to a semiconductor device fabrication and an MEMS(Micro-Electro-Mechanical System) process, including the steps of forming an etching mask on a substrate, forming a plurality of patterns in the etching mask corresponding to depths of the plurality of trenches; and etching the substrate using the etching mask having the plurality of patterns formed therein, whereby eliminating an alignment error in respective photolithography, that permits to form a precise structure, simplify a fabrication process, and reduce a production cost.

Etching method

Light source module with two wavelengths including a first and a second laser diodes each for emitting a laser beam with a wavelength different from each other, and a submount formed between the first and second laser diodes having a vertical mirror surface vertical to bonding surfaces of the first and second laser diodes for reflecting laser beams from the first and second laser diodes in a same direction.
