A METHOD OF ASSEMBLING WAFERS BY MOLECULAR BONDING

摘要

The invention concerns a method of bonding two wafers (20, 30) by molecular bonding in which a first propagation of a bonding wave initiated from a point of pressure (43) applied to at least one (30) of the two wafers is followed by a second propagation of the bonding wave over a zone covering the point of pressure (43). The second bonding wave propagation may be obtained by interposing a separating element (41) between the two wafers and by withdrawing the element at least after the start of the first bonding wave propagation.
