Abstract:
The invention relates to a method for producing chips ( 13 ) by dividing a wafer along dividing lines ( 11, 12 ) defining dimensions of the chip, wherein a focus ( 18 ) of a preferably pulsed laser radiation ( 16 ) is moved along the dividing lines on a first and at least a second path ( 25, 26 ) within the wafer body, wherein the laser radiation is applied to the wafer from a rear side ( 17 ) of the wafer, and the power density for producing the defects ( 28 ) on the first path ( 25 ) is lower than the power density for producing the defects ( 29 ) on the second path ( 26 ), and/or the number of defects on the first path is smaller than the number of defects on the second path.

Claim (Index 14):
A device as in  claim 10 wherein a falling gradient of internal stresses is formed from the second path mark to the first path mark, with the internal stresses induced by the defects in the lateral surface, wherein the falling stress gradient is formed by a lower power density used to produce defects on the first path mark and a higher power density used to produce defects on the second path mark, wherein the internal stresses induced along the first and second path marks by the defects.
