Abstract:
1. A method for configuring a process for treating a semiconductor wafer, the method comprising: selecting a target thickness to be obtained for a processed semiconductor layer of the semiconductor wafer, which semiconductor layer is to be transferred from a donor substrate; selecting a target maximum density of through holes to extend completely through the processed semiconductor layer; selecting a finishing sequence of operations to be conducted on the semiconductor layer after transfer thereof in order to improve surface quality of the transferred semiconductor layer to provide the processed semiconductor layer wherein the selected finishing sequence includes at least one shallow-hole reducing operation that reduces depth of shallow holes that are present in the transferred layer, which shallow holes extend less than completely through the transferred layer; and determining a minimum layer thickness of the transferred layer to be provided by: wherein said minimum thickness is determined such that the density of through holes is below said target maximum density after each operation in the finishing sequence, and such that the target thickness is achieved when the finishing sequence is complete.
