Abstract:
1. A method of forming an elevated containment structure surrounding a surface of a semiconductor wafer comprising: depositing a layer of liquid material on the surface of the semiconductor wafer; selectively curing a portion of the layer of the liquid material along a peripheral edge of the surface of the semiconductor wafer to at least a semisolid state to form a first layer of the elevated containment structure bonded to the surface of the semiconductor wafer; depositing at least another layer of the liquid material on the surface of the semiconductor wafer; and selectively curing a portion of the at least another layer of the liquid material along the peripheral edge of the surface of the semiconductor wafer to at least a semisolid state to form at least another layer of the elevated containment structure bonded to and superimposed over the first layer of the elevated containment structure.
