Abstract
리드 프레임의 다이 패드의 측변에 슬릿(slit)이 형성되고, 그 슬릿내에 까지 연장된 내부 리드가 적어도 1개 이상 형성되어 그 다이 패드 자체의 스크레스가 감소하고, 양산성이 우수하며, 그 리드 프레임을 이용한 반도체 칩 패키지의 신뢰성이 향상되는 효과가 있다.A slit is formed on the side of the die pad of the lead frame, and at least one internal lead extending to the slit is formed, thereby reducing the scratch of the die pad itself, and excellent in mass productivity. There is an effect of improving the reliability of the semiconductor chip package using.
Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.
