Patent ID: 7679387

Claim:
An inspection method for performing an electrical inspection by bringing a probe into contact with an electrode of a target object to be inspected, comprising: a process of reducing an electrical resistance value between the electrode and the probe to a first predetermined value or less by bringing the probe into contact with the electrode at a predetermined load so as to apply a mechanical damage to an insulating film on the electrode; a fritting process of reducing the electrical resistance value between the electrode and the probe to a second predetermined value or less which is smaller than the first predetermined value by applying an electrical damage to the insulating film on the electrode by means of a fritting phenomenon; a switching process of connecting the probe to a test circuit from a fritting circuit; a process of performing the electrical inspection of the target object by the test circuit; and performing a probe leading end shaping process by forming an irregularity in a leading end portion of the probe whenever a preset number of the electrical inspections on the target object to be inspected is carried out.
