    • The present invention discloses a chip scale package. According to this invention, a lead frame 130 is bonded with an adhesive 140 to a bottom face of a semiconductor chip 110. An inner lead 131 of the lead frame 130 is connected to a pad 111 of the semiconductor chip with a metal wire 120, and thickness of the inner lead 131 is equal to an original thickness of the lead frame 130. An outer lead 132 of the lead frame 130 is formed by partially etching a bottom face of the lead frame 130. The entire resultant is encapsulated with a molding compound 100 such that the outer lead 132 is exposed therefrom, especially there is formed a downward protruding portion 101 at the molding compound 100 in the lower inner lead portion 131. This protruding portion raises the margin controlling the bonding height during the wire-bonding process such that the metal wire 120 is not exposed from the molding compound 100. Furthermore, the outer leads 134 at both sides where no solder balls are mounted on, are exposed from the molding compound 100. The outer leads 132 at both sides being exposed from the molding compound 100 act for dissipating outwardly heat that is transmitted from the semiconductor chip 110 to the lead frame 130. A solder ball 150 is mounted at the inside of the outer lead 132 exposed from the molding compound 100.
    • 本发明公开了一种芯片级封装。 根据本发明,引线框架130用粘合剂140粘合到半导体芯片110的底面。引线框架130的内引线131通过金属线120连接到半导体芯片的焊盘111, 并且内引线131的厚度等于引线框架130的原始厚度。引线框架130的外引线132通过部分蚀刻引线框架130的底面而形成。整个结合物被封装成型 化合物100,使得外引线132暴露于其中,特别是在下内引线部分131中的模塑料100处形成向下突出部分101.该突出部分在引线接合过程中增加控制接合高度的边缘 使得金属线120不会从模塑料100暴露出来。此外,没有焊球的两侧的外引线134从模塑料100露出。外部的I 从模制化合物100露出的两侧的阴极132用于散发从半导体芯片110传递到引线框架130的向外的热。焊球150安装在从模塑料暴露的外引线132的内部 100。
