               1. A semiconductor device, comprising: 
            a substrate; 
                a bonding structure disposed on the substrate; 
                a bit line disposed on the bonding structure; 
                a channel layer disposed on the bit line, and comprising a first doped region and a second doped region; and 
                a word line surrounding the first doped region and the second doped region of the channel layer, 
                wherein the bonding structure comprises a dielectric material, and 
                wherein the first doped region has a first conductive type, and the second doped region has a second conductive type different from the first type.
