Abstract
Disclosed are a memory, a semiconductor structure, and a manufacturing method thereof. The manufacturing method includes: providing a substrate, where the substrate includes bit line structures, a first isolation layer covering sidewalls of the bit line structures and a second isolation layer covering a surface of the first isolation layer; removing the second isolation layer on a top of the first isolation layer to expose the top of the first isolation layer, and removing the first isolation layer so as to form a void between the bit line structure and the second isolation layer; and forming a sealing layer covering an opening of the void.
