Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. The method for manufacturing a semiconductor structure of claim 1, wherein the removing at least a part of the preset barrier layer corresponding to the peripheral region, so as to expose a part of the substrate, and to take a reserved part of the preset barrier layer as a first barrier layer comprises:
forming a first photoresist layer on the preset barrier layer, wherein the first photoresist layer at least covers a part of the preset barrier layer corresponding to the core region;
etching the preset barrier layer by taking the first photoresist layer as a mask, so as to take the reserved part of the preset barrier layer that is etched as the first barrier layer; and
removing the first photoresist layer.
