Abstract:
1. A method of manufacturing a semiconductor device comprising: forming a plurality of electrodes on a first major surface of a semiconductor substrate having first and second major surfaces facing in opposite directions, wherein forming a cleavage-inducing pattern layer on the first major surface of the semiconductor substrate, wherein forming a recess in the cleavage-inducing pattern layer, wherein the recess extends only partly through the cleavage-inducing pattern layer and faces the target cleavage position on the first major surface of the semiconductor substrate; forming a scribed groove in the second major surface of the semiconductor substrate, wherein the scribed groove is located in a position facing the target cleavage position; and cleaving the semiconductor substrate having the scribed groove and the cleavage-inducing pattern layer by applying pressure, through a cleaving placed in contact with the cleavage-inducing pattern layer, to the first major surface of the semiconductor substrate.
