Semiconductor structure and forming method thereof

A method for manufacturing a bit line structure includes the following operations. A bit line conductive layer is formed on a surface of a semiconductor substrate, and the bit line conductive layer is partially located in a groove in the surface of the semiconductor substrate. A first protective layer is formed on surfaces of the bit line conductive layer and the semiconductor substrate. A first barrier layer is formed on a surface of the first protective layer. The surface of the first barrier layer is subjected with passivating treatment. A sacrificial layer is formed on the surface of the first barrier layer, and is provided with a filling part filled in the groove. A part, other than the filling part, of the sacrificial layer is cleaned and stripped.
