    • A manufacturing method of semiconductor device is provided to improve the adhesive strength by increasing the contact area between the PIQ layer and the metal pad. An inter-layer insulating film(305) is formed at the upper part of semiconductor substrate(300). The inter-layer insulating film is etched and the trench is created. The metal pad is formed on the upper part of interlayer insulating film in which the trench is created. The step height is formed at the metal pad by the trench. A passivation layer(340) is formed on the whole upper unit including the metal pad(325) in which the step height is formed. The passivation layer on the metal pad is etched. The part of passivation layer remains on the surface of metal pad. The PIQ(Polyimide Isoindro Quirazorindione) layer(345) is formed at the step difference upper part and the side wall of the etched passivation layer. Curing and etching process are performed in the PIQ layer and the metal pad is opened.
    • 提供半导体器件的制造方法,通过增加PIQ层和金属焊盘之间的接触面积来提高粘合强度。 在半导体衬底(300)的上部形成层间绝缘膜(305)。 蚀刻层间绝缘膜并产生沟槽。 金属焊盘形成在其中形成沟槽的层间绝缘膜的上部。 通过沟槽在金属焊盘处形成台阶高度。 在包括形成台阶高度的金属垫(325)的整个上部单元上形成钝化层(340)。 蚀刻金属焊盘上的钝化层。 钝化层的一部分保留在金属垫的表面上。 在蚀刻的钝化层的台阶差上部和侧壁上形成PIQ(聚酰亚胺Isoindro喹唑啉二酮)层(345)。 在PIQ层中进行固化和蚀刻处理,并打开金属垫。
