A method for determining a suitable implanting energy of at least two atomic species in a donor substrate to create a weakened zone defining a monocrystalline semiconductor layer to be transferred onto a receiver substrate, comprises the following steps: (i) forming a dielectric layer on at least one of the donor substrate and the receiver substrate; (ii) co-implanting the species in the donor substrate; (iii) bonding the donor substrate on the receiver substrate; (iv) detaching the donor substrate along the weakened zone to transfer the monocrystalline semiconductor layer and recover the remainder of the donor substrate; (v) inspecting the peripheral crown of the remainder of the donor substrate, or of the receiver substrate on which the monocrystalline semiconductor layer was transferred at step (iv); (vi) if the crown exhibits zones transferred onto the receiver substrate, determining the fact that the implanting energy at step (ii) is too high; (vii) if said the crown does not exhibit zones transferred onto the receiver substrate, determining the fact that the implanting energy at step (ii) is suitable.

A three-dimensional (3D) bonded semiconductor structure is provided in which a first bonding oxide layer of a first semiconductor structure is bonded to a second bonding oxide layer of a second semiconductor structure. Each of the first and second bonding oxide layers has a metallic bonding structure embedded therein, wherein each metallic bonding structure contains a columnar grain microstructure. Furthermore, at least one columnar grain extends across a bonding interface that is present between the metallic bonding structures. The presence of the columnar grain microstructure in the metallic bonding structures, together with at least one columnar grain microstructure extending across the bonding interface between the two bonded metallic bonding structures, can provide a 3D bonded structure having mechanical bonding strength and electrical performance enhancements.

Small size chip handling and electronic component integration are accomplished using handle fixturing to transfer die or other electronic components from a full area array to a targeted array. Area array dicing of a thinned device wafer on a handle wafer/panel may be followed by selective or non-selective de-bonding of targeted die or electronic components from the handle wafer and optional attachment to a carrier such as a transfer head or tape. Alignment fiducials may facilitate precision alignment of the transfer head or tape to the device wafer and subsequently to the targeted array. Alternatively, the dies or other electronic elements are transferred selectively from either a carrier or the device wafer to the targeted array.
