    • A semiconductor device package fabrication method is proposed, which is used for the fabrication of a semiconductor device package of the type having a core-hollowed portion that is typically used to house an optically-sensitive semiconductor device such as an image sensor or an ultraviolet-sensitive EPROM (Electrically-Programmable Read-Only Memory) device. The proposed method is characterized in the use of a support pillar, which is positioned beneath the lead frame when the lead frame is clamped between a top inserted mold and a bottom cavity mold, to help prevent resin flash on the lead frame during the molding of the core-hollowed portion. As a result, the proposed method can help strengthen the bonding of the semiconductor device on the die pad as well as the wire bonding on the inner end of the finger portion of the lead frame, Moreover, since the making of the support pillar would be significantly cheaper and easier to implement than the use of an organic high-molecule coating and a solvent as in the case of the prior art flash prevention, the proposed method is more cost-effective and environmentally-friendly to use than the prior art.
    • 提出了一种半导体器件封装制造方法,其用于制造具有芯空心部分的类型的半导体器件封装,该芯 - 中空部分通常用于容纳诸如图像传感器或紫外线照射的光敏半导体器件, 灵敏的EPROM(电可编程只读存储器)器件。 所提出的方法的特征在于当引线框架被夹持在顶部插入的模具和底部空腔模具之间时,位于引线框架下方的支撑柱的使用,以帮助防止在成型期间引线框架上的树脂闪光 芯 - 中空部分。 结果,所提出的方法可以有助于加强半导体器件在芯片焊盘上的接合以及引线框架的指状部分的内端上的引线接合。此外,由于支撑柱的制造将是 与使用现有技术闪光灯防止的情况相比,使用有机高分子涂层和溶剂显着地便宜且易于实现,所提出的方法比现有技术更具成本效益和使用环境友好性。
