PURPOSE: A non-destructive inspection method and an apparatus for a semiconductor chip are provided to improve the productivity and reliability of a semiconductor chip. CONSTITUTION: The non-destructive inspection method includes : a first step of generating a laser light ranging in wavelength from 300 nm to 1,200 nm, and generating a laser beam converging into a predetermined beam diameter; a second step of predetermined electrical connection means configuring a predetermined current path for passing an OBIC current(6) generated by an OBIC phenomenon when the laser beam is radiated onto the p-n junction and the vicinity of the p-n junction formed in the semiconductor chip to be inspected at least in the substrate including a wafer state and an installation state during the production process; a third step of scanning a predetermined area of a semiconductor chip while radiating the laser beam; a fourth step of magnetic flux detection means detecting magnetic flux induced by an OBIC current generated by the laser beam at each radiation point scanned in the third step; and a fifth step of determining whether or not there is a resistance increase defect including a disconnection defect or a leak defect including a short circuit defect in a current path.
