The TSV template wafer is obtained by thinning a semiconductor wafer, which facilitates reducing the difficulty in etching and filling. Connection parts are provided on the TSV template wafer, for convenience of interconnection between the overlying and underlying production wafers, which facilitates reducing the difficulty in alignment and improving the convenience of design of electrical connection for 3D devices. |
