Abstract:
1. A method for forming a direct fusion bond between fractional components of a semiconductor laminate structure, the method comprising: generating one or more direct bonding surfaces on each of a plurality of semiconductor wafers; cutting a first fractional component and a second fractional component from at least one of the plurality of semiconductor wafers, wherein the first fractional component comprises a first direct bonding surface of the one or more direct bonding surfaces and the second fractional component comprises a second direct bonding surface of the one or more direct bonding surfaces; drying the first direct bonding surface of the first fractional component and the second direct bonding surface of the second fractional component; constraining the first fractional component with an assembly block; placing the second direct bonding surface of the second fractional component into contact with the first direct bonding surface of the first fractional component to define an initial contact area, wherein an angle of approach is formed between the second direct bonding surface of the second fractional component and the first direct bonding surface of the first fractional component; and closing the angle of approach between the second direct bonding surface of the second fractional component and the first direct bonding surface of the first fractional component to create a direct fusion bond of a semiconductor laminate structure, wherein the direct fusion bond is larger than the initial contact area.
