Abstract: A substrate is provided. A first dielectric is formed over the substrate, and an etching stop layer and a second dielectric are formed in turn on the first dielectric by deposition. An anti-reflection layer is formed over the second dielectric. Then, a photo-resist layer is formed and defined over the anti-reflection layer. A gap-filling material is filled on the second dielectric and into the via hole. Subsequently, the gap-filling material is etched back and is turned on the end point and the long over etch is applied to make sure the photo-resist thickness is below middle stop layer. If the first dielectric reacts with the photo-resist plug in the via hole, the bottom anti-reflection coating or thin oxide are used as a barrier before the trench photo-resist is patterned. If the first dielectric does not react with the photo-resist plug in the via hole, the trench photo-resist is patterned directly. Then, the trench etch is performed.
