摘要:
In a method of manufacturing a semiconductor device, a preliminary insulating layer is formed on a substrate. A photoresist pattern is formed on the preliminary insulating layer. A central portion of the preliminary insulating layer is partially etched using the photoresist pattern as an etch mask to form a preliminary insulating layer pattern including a central portion and a peripheral portion on the substrate. The peripheral portion of the photoresist pattern is higher than that of the central portion of the preliminary insulating layer pattern. The preliminary insulating layer pattern is polished to form a planarized insulating layer on the substrate.
