A CMP process may be used to remove the remaining P− layer until the N+ silicon layer 9602 is reached. This process of an ion implanted atomic species, such as Hydrogen, forming a layer transfer demarcation plane, and subsequent cleaving or thinning, may be called 'ion-cut'.

The process of lapping has been long considered an art due to the tremendous amount of variability and subjectivity involved. The quality of lapping differs from operator to operator and the results are highly inconsistent. The material removal rate, surface finish, and flatness all depend on the proper control of lapping parameters such as
