Abstract
Embodiments provide a semiconductor structure and a method thereof. The method includes: providing a first substrate, and forming a drive pad on the first substrate; providing a second substrate, and forming active pillars and a bit line in sequence on a side of the second substrate, wherein a side of the bit line is connected to the active pillars, and a surface of the bit line facing away from the active pillars is exposed on a surface of the second substrate; bonding the bit line to the drive pad correspondingly; thinning the second substrate from a side of the second substrate facing away from the first substrate until the active pillars are exposed; and forming a storage capacitor on sides of the active pillars facing away from the drive pad, the storage capacitor being connected to the active pillars.
