Abstract

PURPOSE:To avoid contamination of the main surface of a semiconductor substrate in the semiconductor device by forming grooves necessary to divide the substrate on the other opposite side main surface thereof when dividing semiconductor element group formed on one main surface of the substrate into unit elements and dividing the substrate along the grooves into the unit elements. CONSTITUTION:Unit elements 4 are formed on one main surface 2 of the semiconductor substrate 1, dividing lines 5 are formed around the elements 4, one main surface 2 is placed through a protecting transparent thin film 7 on a ringlike table 10 while directing the dividing lines 5 downwardly. Subsequently, a laser light source 8 is arranged on the opposite side main surface 3 of the substrate 1, and a position detector 9 such as a reflection type optical microscope or the like is arranged coaxially with the source 8 on the main surface 2 side, a laser light is irradiated to the opposite main surface 3, the table 10 is simultaneously moved together with the substrate 1 thereon, and the light source 8 and the detector 9 are coaxially moved with the dividing lines 5. Thus there are formed molten grooves 6 confronting the dividing lines 5, and the substrate is divided into the unit element 4 by using a dicing saw or the like along the grooves 6 as reference.
