The semiconductor device comprises a semiconductor structure, a transition channel structure array and a virtual channel structure array, wherein the transition channel structure array and the virtual channel structure array are arranged in the semiconductor structure and are adjacently arranged in a first direction; the transition channel structure array comprises an edge transition channel structure column adjacent to the virtual channel structure array, the edge transition channel structure column comprises aplurality of edge transition channel structures arranged at intervals in the second direction, and the second direction is perpendicular to the first direction; the virtual channel structure array comprises an edge virtual channel structure column adjacent to the edge transition channel structure column, and the edge virtual channel structure column comprises a plurality of edge virtual channel structures arranged at intervals in the second direction; the shortest distance connecting line direction between any edge virtual channel structure and the adjacent edge transition channel structure deviates from the first direction. The problem of sharp corners of the edge virtual channel holes can be avoided, and therefore electric leakage of the three-dimensional storage device is avoided.
