Embodiments relate to the field of semiconductor manufacturing technology, and more particularly, to a method for fabricating a semiconductor structure and a semiconductor structure. The method for fabricating a semiconductor structure provided by the embodiments of the present disclosure includes: providing a substrate including an array region and a peripheral region; forming a first mask layer covering the array region and the peripheral region on the substrate; forming a first device structure pattern on the first mask layer, and then forming a second device structure pattern on the first mask layer; and etching the substrate by using the first device structure pattern and the second device structure pattern as mask layer to form a peripheral region structure and an array region structure synchronously on the substrate. Technological processes are simplified, fabrication difficulties are reduced, and production efficiency is improved.

Method for fabricating semiconductor structure, and semiconductor structure

Embodiments relate to the field of semiconductor manufacturing technology, and more particularly, to a method for fabricating a semiconductor structure and a semiconductor structure. The fabricating method includes: providing a substrate including an array region and a peripheral region; and forming, on the substrate, a first mask layer covering the array region and the peripheral region, the first mask layer having a first device structure pattern directly facing the array region and a second device structure pattern directly facing the peripheral region. Through the method for fabricating a semiconductor structure, the first mask layer having the first device structure pattern and the second device structure pattern is formed on the substrate, and then the substrate is etched by using the first device structure pattern and the second device structure pattern as mask layer to synchronously form a peripheral region structure and an array region structure on the substrate.
