Abstract

패키지 몸체에 하부면에 반도체 칩이나 다이패드등이 노출되어 있는 UTSOP형 반도체 패키지에서 외부리이드들이 패키지 몸체의 하부로 ㄷ자 형상으로 절곡되어 있으며, 상기 외부리이드들의 단부와 상기 노출된 반도체 칩이나 다이패드의 사이에 절연성 폴리머층을 개재시켜 상기 외부리이드들의 단부를 절연성 폴리머층과 접착시켜 반도체 패키지를 형성하였으므로, 외부리이드가 차지하는 실장면적이 감소되어 고밀도실장에 유리하고, 절연성 폴리머층에 의해 납땜 리플로우 공정시의 외부리이드와 반도체 칩이나 다이패드간의 단락을 방지하므로 공정수율 및 소자동작의 신뢰성을 향상시킬 수 있는 잇점이 있다.In the UTSOP-type semiconductor package in which a semiconductor chip or a die pad is exposed on the bottom surface of the package body, external leads are bent in a U shape at the bottom of the package body, and ends of the external leads and the exposed semiconductor chip or die pad are exposed. Since the semiconductor package is formed by bonding the ends of the outer leads with the insulating polymer layer through the insulating polymer layer, the mounting area occupied by the outer leads is reduced, which is advantageous for high density mounting, and the solder reflow is performed by the insulating polymer layer. Since the short circuit between the external lead during the process and the semiconductor chip or the die pad is prevented, there is an advantage that the process yield and the reliability of device operation can be improved.
