Selected areas in one of the semiconductor layers are amorphized; in-place bonding is then performed in a wet etch solution to remove the sacrificial layer and leave the semiconductor layers bonded to each other. Furthermore, multiple instances of the sorting, counting and merging processes can be used in parallel to reduce the time required to regenerate the reference counts for a large number of objects. 9, a phase angle, \u03b4, of less than about 55 degrees at a complex modulus of 10 kPa, measured at 190\xb0 C.
