摘要:
A method for creating an extremely thin semiconductor-on-insulator (ETSOI) layer having a uniform thickness includes: measuring a thickness of a semiconductor-on-insulator (SOI) layer at a plurality of locations; determining a removal thickness at each of the plurality of locations; and implanting ions at the plurality of locations. The implanting is dynamically based on the removal thickness at each of the plurality of locations. The method further includes oxidizing the SOI layer to form an oxide layer, and removing the oxide layer.
