Abstract
The semiconductor inspecting method includes following steps. First, a first position of a probe needle from above is defined by adopting a vision system of a semiconductor inspecting system. Then, a first relative vertical movement between the probe needle and the pad is made by adopting a driving system of the semiconductor inspecting system. Thereafter, a minimum change in position of the probe needle corresponding to the first position is recognized by adopting the vision system of the semiconductor inspecting system. Next, the first relative vertical movement is stopped by adopting the driving system of the semiconductor inspecting system.
