The invention provides a groove forming method and a semiconductor structure. The groove forming method comprises a semiconductor substrate. A patterned hard masking film layer is formed on the semiconductor substrate and provided with an opening. The thickness of the patterned hard masking film layer ranges from 100nm to 400nm. The patterned hard masking film layer is used as a masking film, the semiconductor substrate undergoes etching. A groove is formed in the semiconductor substrate. According to the groove forming method, manufacturing technologies or cost of materials is not added, and a groove filled by polycrystalline silicon materials or insulating materials in a benefited mode is formed according to the forming method which is simple in technology and low in cost.
