    摘要: Structures for aligning wafers and methods for operating the same. The structure includes (a) a first semiconductor wafer including a first capacitive coupling structure, and (b) a second semiconductor wafer including a second capacitive coupling structure. The first and second semiconductor wafers are in direct physical contact with each other via a common surface. If the first and second semiconductor wafers are moved with respect to each other by a first displacement distance of 1 nm in a first direction while the first and second semiconductor wafers are in direct physical contact with each other via the common surface, then a change of at least 10−18 F in capacitance of a first capacitor comprising the first and second capacitive coupling structures results. The first direction is essentially parallel to the common surface.
