Patent ID: 7183179

Claim:
A hydrogen (H) exfoliation gettering method for attaching fabricated circuits to receiver substrates, the method comprising: forming a Si-on-insulator (SOI) substrate with a buried oxide (BOX) layer; forming a Si active layer overlying the substrate with circuit source/drain (S/D) regions; implanting a p-dopant into the S/D regions; forming gettering regions underling the S/D regions; implanting H in the Si substrate, forming a cleaving plane in the Si substrate about as deep as the gettering regions, with a horizontal peak concentration (Rp) H layer in regions of the Si substrate underlying the S/D regions; bonding the circuit to a receiver substrate; cleaving the Si substrate along the cleaving plane by cleaving a first region along the horizontal Rp layer in the regions underlying the S/D) regions; cleaving a second region along a horizontal interface between the BOX layer and Si substrate underlying the channel region; and cleaving vertically between the first and second regions; and binding the implanted H underlying the S/D regions with p-dopant in the gettering regions.
