发明名称 METHODS FOR PREPARING LAYERED SEMICONDUCTOR STRUCTURES
摘要 Methods for preparing layered semiconductor structures are disclosed. The methods may involve pretreating an ion-implanted donor wafer by annealing the ion-implanted donor wafer to cause a portion of the ions to out-diffuse prior to wafer bonding. The donor structure may be bonded to a handle structure and cleaved without re-implanting ions into the donor structure.

主权项 1. A method for pretreating a structure for use during preparation of a layered semiconductor structure, the structure having a bonding surface for bonding to a second structure, the method comprising: implanting ions into the structure to form a cleave plane in the structure; annealing the ion-implanted structure to cause a portion of the ions to out-diffuse; activating the bonding surface of the ion out-diffused structure.
