    • PURPOSE: A ball-grid-array package and a method for manufacturing the same are provided to reduce the stress of thermal expansion by molding the minimum part of the package. CONSTITUTION: A first substrate(100) is composed of three stepped parts. A first loading part is formed on a first stepped part, and a second loading part is formed on a third stepped part. A through hole passing through the first loading part and the second loading part is formed on a second stepped part. A first semiconductor chip(170) is mounted on the first loading part, and a second semiconductor chip(160) is mounted on the second loading part. A first mold(150) molds the first loading part. The first substrate is mounted on a second substrate(180), and an external connecting terminal is formed on the second substrate. A second mold(200) is molded to expose the first substrate.
    • 目的:提供球栅阵列封装及其制造方法,以通过模制封装的最小部分来减少热膨胀的应力。 构成:第一基板(100)由三个台阶部分组成。 第一装载部分形成在第一阶梯部分上,第二装载部分形成在第三阶梯部分上。 穿过第一装载部分和第二装载部分的通孔形成在第二台阶部分上。 第一半导体芯片(170)安装在第一装载部分上,第二半导体芯片(160)安装在第二装载部分上。 第一模具(150)模制第一装载部件。 第一基板安装在第二基板(180)上,并且在第二基板上形成外部连接端子。 模制第二模具(200)以暴露第一基板。
