Method of wafer-to-wafer bonding
Abstract:
Methods of wafer-to-wafer bonding are disclosed. These methods use a force-transposing substrate providing redistribution of the applied force to the local bonding areas across the wafer. Certain versions of the Present Invention also provide a compliant force-distributing member along with applying bonding material to bonding areas in selectable locations. A predetermined sequence of external force loading and temperature steps ensure creating bonds between the wafers in the bonding areas. The disclosed methods improve wafer bonding, by increasing its uniformity and strength across the wafer, increase both reproducibility and yield process and decrease cost of semiconductor and MEMS devices.
