METHODS FOR BONDING SUBSTRATES

Methods for bonding substrates used, for example, in substrate-level packaging, are provided herein. In some embodiments, a method for bonding substrates includes: performing electrochemical deposition (ECD) to deposit at least one material on each of a first substrate and a second substrate, performing chemical mechanical polishing (CMP) on the first substrate and the second substrate to form a bonding interface on each of the first substrate and the second substrate, positioning the first substrate on the second substrate so that the bonding interface on the first substrate aligns with the bonding interface on the second substrate, and bonding the first substrate to the second substrate using the bonding interface on the first substrate and the bonding interface on the second substrate. 本文提供例如在基板级封装中使用的用于粘合基板的方法。在一些实施例中，一种用于粘合基板的方法包括：执行电化学沉积(ECD)以在第一基板和第二基板中的每一者上沉积至少一种材料；在第一基板和第二基板上执行化学机械抛光(CMP)以在第一基板和第二基板中的每一者上形成粘合界面；将第一基板定位在第二基板上，使得第一基板上的粘合界面与第二基板上的粘合界面对齐；以及使用第一基板上的粘合界面和第二基板上的粘合界面来将第一基板粘合至第二基板。
