摘要:
A method for forming a bump of a semiconductor device and a bump formed by using the same are provided to improve the thickness uniformity of a barrier coating layer and a bump coating layer on various pad electrodes by forming the barrier coating layer and the bump coating layer with an electrolytic plating method. A substrate(100) has a pad electrode(110). A seed layer(120) is formed on the substrate including the pad electrode. A mask layer having an opening is formed on the seed layer. The opening is overlapped with the pad electrode. A barrier coating layer(130) is formed in the opening by using an electrolytic plating method. A bump coating layer(150) is formed on the barrier coating layer by using an electrolytic plating method. The mask layer is removed to expose the seed layer. The exposed seed layer is etched by using the bump layer as a mask. Before the bump coating layer is formed, a bump adhesive layer(140) is formed on the barrier coating layer.
摘要(中):
提供一种用于形成半导体器件的凸起的方法和使用该凸起形成的凸块,以通过形成阻挡涂层和凸块涂覆层来改善各种焊盘电极上的阻挡涂层和凸块涂覆层的厚度均匀性 用电解电镀法。 基板(100)具有焊盘电极(110)。 在包括焊盘电极的基板上形成种子层(120)。 在籽晶层上形成具有开口的掩模层。 开口与焊盘电极重叠。 通过使用电解电镀法在开口中形成阻挡涂层(130)。 通过使用电解电镀法在阻挡涂层上形成凸点涂层(150)。 去除掩模层以暴露种子层。 通过使用凸起层作为掩模来蚀刻暴露的种子层。 在形成凸点涂层之前,在阻挡涂层上形成凸块粘合剂层(140)。
