Patent number: 8044420Abstract: The present invention relates to a method for forming a package structure for a light emitting diode (LED) and the LED package structure thereof. By employing the same sawing process to cut through the trenches of the leadframe, the package units are singulated and different lead portions are simultaneously separated from each other in each package unit. Therefore, the overflow issues of the encapsulant can be avoided without using extra taping process.Type: GrantFiled: January 15, 2009Date of Patent: October 25, 2011Assignee: Advanced Semiconductor Engineering, Inc.Inventors: Seongoo Lee, Ryungshik Park, Hyunil Lee, Hyunsoo Jeong
