3DIC互连装置和方法
摘要：
本发明提供了一种互连装置及其形成方法。将两个衬底（诸如晶圆、管芯、或晶圆和管芯）接合在一起。使用第一掩模形成部分地延伸至形成在第一晶圆上的互连件的第一开口。形成介电衬层，然后使用相同的掩模实施另一个蚀刻工艺。继续蚀刻工艺以暴露出形成在第一衬底和第二衬底上的互连件。用导电材料填充开口以形成导电插塞。本发明还公开了3DIC互连装置和方法。
摘要（英）：

An interconnect apparatus and a method of forming the interconnect apparatus is provided. Two substrates, such as wafers, dies, or a wafer and a die, are bonded together. A first mask is used to form a first opening extending partially to an interconnect formed on the first wafer. A dielectric liner is formed, and then another etch process is performed using the same mask. The etch process continues to expose interconnects formed on the first substrate and the second substrate. The opening is filled with a conductive material to form a conductive plug.
