IMPRITING STAMP FOR FORMING PATTERN AND METHOD OF FABRICATING LED PACKAGE USING THE SAME

摘要

An imprinting stamp for a pattern formation and a method for manufacturing an LED(Light Emitting Diode) package using the same are provided to improve the light extraction efficiency of the LED package by forming a guard or barrier along a boundary of a groove section corresponding to LED package structures. LED package structures with LED chips are arranged on a co-plane by an imprinting method to configure an LED package set. A stamp is used for forming an unevenness pattern(310) on a surface of a resin package of the respective LED package structures. A groove section is prepared on a surface of the stamp corresponding to the LED package structure. A plurality of unevenness patterns are prepared in the stamp. A guard or barrier is formed along a boundary of the groove section corresponding to the respective LED package structures. The imprinting stamp is a soft stamp that is made of a polymer mater ial.
