A TSV bidirectional repair circuit of a semiconductor apparatus is provided. The bidirectional repair circuit includes a first and a second bidirectional switches and at least two transmission path modules. The first and the second bidirectional switches determine whether to transmit an input signal of a first chip or a second chip to each of the transmission path modules according to a switch signal. Each transmission path module includes at least two data path circuits and corresponding TSVs. Each data path circuit includes an input driving circuit, a short-circuit detection circuit and a leakage current cancellation circuit. The short-circuit detection circuit detects whether short-circuit on the corresponding TSV and a silicon substrate is present according to the input signal and the corresponding TSV to produce a short-circuit detection output signal.
