Abstract
A method for manufacturing a semiconductor structure and a semiconductor structure are provided. The method includes the following steps. A bit line structure is formed on a substrate. Each of the bit lines is provided with an insulation block on a side facing away from the substrate. A shielding portion is formed on a top of the insulation block that faces away from the substrate. A projection area of the shielding portion on the substrate is larger than a projection area of the insulation block on the substrate. An insulation sidewall is formed on a sidewall of the bit line and a sidewall of the insulation block, and a gap extending to the substrate is formed within the insulation sidewall corresponding to the shielding portion.
