The invention relates to the technical field of semiconductors, and discloses a defective product maintenance table for semiconductor processing, which comprises a working table, and the top of the working table is fixedly connected with a bracket and a fixed table. According to the defective product maintenance platform for semiconductor processing, the guide mechanism, the transverse guide mechanism and the vacuum chuck are arranged, a semiconductor chip is sucked through the vacuum chuck, a first motor of the guide mechanism is started, an output shaft of the first motor rotates to drive a first threaded rod to rotate, and the first threaded rod rotates to adjust the position of a guide block; a second motor of the transverse guide mechanism is started, an output shaft of the second motor drives a second threaded rod to rotate, the second threaded rod rotates to adjust the position of a sliding block, the sliding block drives a connecting ring to move, the connecting ring drives a lifting mechanism and a moving plate to move, and then the position of the chip can be adjusted; therefore, the position of the semiconductor chip is adjusted, and the position of the chip is convenient to adjust.
