Abstract

A processing apparatus includes a controller configured to control an operation of forming condensing points in a processing target object. In forming the condensing points by radiating a laser light to an inside of the processing target object periodically from a modifying device while rotating the processing target object held by a holder relative to the modifying device by a rotating mechanism and, also, by moving the modifying device in a diametrical direction relative to the holder by a moving mechanism, the controller controls a number and an arrangement of the condensing points, which are simultaneously formed at different positions in a plane direction of the processing target object, based on a relative rotation number of the processing target object and a radiation pitch of the laser light.
