Semiconductor device and manufacturing method thereof
摘要：
There are constituted by a tab (1b) on which a semiconductor chip (2) is mounted, a sealing portion (3) formed by resin-sealing the semiconductor chip (2), a plurality of leads (1a) each having a mounted surface (1d) exposed to a peripheral portion of a rear surface (3a) of the sealing portion (3) and a sealing-portion forming surface (1g) disposed on an opposite side thereto, and a wire (4) for connecting a pad (2a) of the semiconductor chip (2) and a lead (1a), wherein the length (M) between inner ends (1h) of the sealing-portion forming surfaces (1g) of the leads (1a) disposed so as to oppose to each other is formed to be larger than the length (L) between inner ends (1h) of the mounted surfaces (1d). Thereby, a chip mounting region surrounded by the inner end (1h) of the sealing-portion forming surface (1g) of each lead (1a) can be expanded and the size of the mountable chip is increased.
摘要（中）：

由安装有半导体芯片（2）的突片（1b），通过树脂密封半导体芯片（2）形成的密封部分（3），多个引线（1a），其具有安装表面 （1d）暴露于密封部分（3）的后表面（3a）的周边部分和设置在其相对侧上的密封部分形成表面（1g）和用于连接焊盘（4）的焊丝（4） 2a）和引线（1a）之间的长度（M），其中引线（1a）的密封部分形成表面（1g）的内端（1h）之间的长度（M）设置为与 彼此形成为大于安装面（1d）的内端（1h）之间的长度（L）。 由此，可以扩大由每个引线（1a）的密封部形成面（1g）的内端（1h）包围的芯片安装区域，并且可安装芯片的尺寸增大。
