摘要 |
A process for preparing semiconductor pellets from one sheet of a semiconductor wafer is disclosed. In the process of the invention, the semiconductor wafer is divided into a plurality of pellet-forming regions and reinforcing regions are formed between the pellet forming regions and at the peripheral part of the wafer. The reinforcing regions prevent breakage of the wafer without increasing the thickness of the pellets whereby a wafer having a large diameter can be used to obtain many pellets having suitable characteristics from one sheet of the wafer without substantial loss. |
