    • A semiconductor device mounted on a substrate. Outer leads, partially resin-molded, have a greater height above the mounting surface than that of a conventional device. Specifically, each lead projecting from the molded resin has a bent portion which is convex in the direction opposite to the mounting surface, and the length of the lead beyond the bent portion is greater than the distance from the lead portion adjacent to the resin portion of the lead to the mounting surface. The long leads improve reliability during, e.g., heat cycle, tests. In another embodiment, outer leads, partially resin-molded, have reverse J-shaped bent portions, each with a distal end positioned away from the resin. When the bent portions serve as soldering portions, the soldering condition can be easily checked.
    • 安装在基板上的半导体器件。 部分树脂模制的外引线在安装表面上方比传统装置的高度高。 具体地说,从模塑树脂突出的每个引线具有在与安装表面相反的方向上凸出的弯曲部分,并且超过弯曲部分的引线的长度大于与引导部分相邻于树脂部分的距离 导致安装表面。 长引线在例如热循环,测试期间提高了可靠性。 在另一个实施例中,部分树脂模制的外引线具有相反的J形弯曲部分,每个部分的远端远离树脂。 当弯曲部分用作焊接部分时,可以容易地检查焊接条件。

    • A semiconductor device includes a molded resin encapsulating a semiconductor chip, outer leads extending from the molded resin and having free ends, and a resin layer connecting and supporting the outer leads along the entire length of the outer leads. The resin layer may have an activating ability for soldering. A method for manufacturing a semiconductor device includes preparing a semiconductor device having a molded resin and a plurality of outer lead portions extending from the molded resin and connected to a lead frame, forming a resin film on and between the outer lead portions; cutting the lead portions to provide cantilevered outer leads having free ends; lead-forming the outer leads with lead-forming dies while heating the resin film to form a resin layer connecting and supporting the outer leads along the entire lengths of the outer leads, and taking the semiconductor device out of the lead-forming dies after the resin layer has been cured.
    • 半导体器件包括封装半导体芯片的模制树脂,从模制树脂延伸并具有自由端的外部引线以及沿外部引线的整个长度连接和支撑外部引线的树脂层。 树脂层可以具有用于焊接的活化能力。 一种制造半导体器件的方法包括制备具有模制树脂的半导体器件和从模制树脂延伸并连接到引线框架的多个外引线部分,在外引线部分之间和之间形成树脂膜; 切割引线部分以提供具有自由端的悬臂式外引线; 在加热树脂膜的同时对引线形成外引线,以形成沿着外引线的整个长度连接和支撑外引线的树脂层,并且将半导体器件从引线成形模具中取出 树脂层已经固化。
