Abstract: Embodiment provides a semiconductor structure and a fabrication method thereof, and relates to the field of semiconductor technology. The fabrication method includes providing a substrate including a peripheral circuit region and an array region having a memory cell, where the peripheral circuit region includes a first region and a second region. In the present disclosure, a logic device configured to control the memory cell and a magnetic memory device are simultaneously fabricated in the peripheral circuit region by means of a process for fabricating a dynamic random access memory (DRAM), such that the same semiconductor structure has two types of memory structures at the same time. Compared with a technology for fabricating two types of memory structures separately, fabricating steps can be simplified, and fabricating costs can be reduced.
