Abstract
A laser processing method of processing an object to be processed. The object to be processed has a modified portion and a non-modified portion. A modified layer forming step forms a modified layer of the object to be processed by scanning an inner portion of the object with a condensing point of first laser light. The modified layer (i) has a processing speed with second laser light that is lower than a processing speed of a non-modified portion and (ii) is formed below the non-modified portion. A removing step removes a portion of the non-modified portion. The portion of the non-modified portion ranges from a surface of the object to the modified layer. The removing step includes irradiating the portion of the non-modified portion with the second laser light.
