METHOD FOR FRACTURING SEMICONDUCTOR SUBSTRATE, METHOD FOR FRACTURING SOLAR CELL, AND THE SOLAR CELL

摘要

In accordance with the present invention, the dividing grooves 8 are formed so as not to be parallel to cleavage planes of the semiconductor substrate 1, and the semiconductor substrate 1 is bent along the dividing grooves 8, whereby the semiconductor substrate 1 is fractured along the dividing grooves 8.
