Claim Text:
1. A method of providing wafer access in a probe system, the method comprising: docking a first wafer cassette with a loading port of the probe system, wherein the first wafer cassette includes a plurality of first slots, wherein the plurality of first slots is configured to contain a plurality of wafers, wherein at least one of the plurality of first slots contains a wafer, and further wherein, subsequent to the docking the first wafer cassette, the first wafer cassette is in physical contact with the probe system; removing a selected wafer from the first wafer cassette with the probe system; subsequent to the removing, performing a process operation on the selected wafer with the probe system, wherein the performing includes testing an operation of at least a portion of the selected wafer; undocking the first wafer cassette from the loading port of the probe system subsequent to the removing and during the performing, wherein, subsequent to the undocking, the first wafer cassette is not in physical contact with the probe system; subsequent to the undocking, docking a second wafer cassette with the loading port of the probe system; inventorying the second wafer cassette with the probe system subsequent to the docking the second wafer cassette; and placing the selected wafer in the second wafer cassette subsequent to the performing, the undocking the first wafer cassette, the docking the second wafer cassette, and the inventorying.
