Abstract

Disclosed is an electronic part package for improving reflectability of light emitted from a light emitting device, and a method of forming a cavity of the electronic part package to improve the reflectability of light so that the cavity of a ceramic substrate is easily formed to have the desired shape. The cavity of the ceramic substrate has a shape tapered inward so that an inclined side is roundly concave and convex. The method includes shifting a tool that includes a cutting part having a cutting blade formed on an external surface thereof toward the ceramic substrate by a predetermined distance while the tool rotates along with a rotational processing part of a ceramic processing device and returning the tool to an original position of the tool to form a cavity having the inclined side in the ceramic substrate.

Description

Technical field [0001] The invention relates to an electronic component package and a method of forming a cavity of the electronic component package. More specifically, the present invention relates to an electronic component package that maximizes the luminous efficiency of light emitted from a light emitting device and a method of forming a cavity in a ceramic substrate of the electronic component package through a simple process. Background technique [0002] Light-emitting diodes (hereinafter referred to as LEDs) are semiconductor devices that can provide various colors. The LED contains a light emitting source, which is provided to change compound semiconductor materials such as GaAs, AlGaAs, GaN, InGaN, and AlGaInP. Currently, packaged semiconductor devices are applied to electronic parts. [0003] Generally, the standard for determining the performance of LED devices is the range of color, brightness, and luminous intensity. The performance of the LED device is determined ...
