Claim:
1. A method fabricating a semiconductor device utilizing a metrology system, the method comprising: receiving, at a metrology tool in the metrology system, a part, wherein the part is a fabricated part in a fabrication process for semiconductor devices; identifying, with a visual sensor in communication with the metrology tool, a part type associated with the part; retrieving, with the processing device, test rule logic associated with the part type from a database, wherein the test rule logic includes a threshold value of parts that should be measured; retrieving, with the processing device, previous measurement data associated with the identified part type that includes a number of parts measured; determining, with the processing device, if the number of parts measured is equal to or exceeds the threshold value of parts that should be measured; processing, with the processing device, the previous measurement data, including calculating a process capability index (C applying, with the processing device, the test rule logic to the processed previous measurement data including the C outputting, from the metrology tool, the part in response to determining that the part should not be measured; and incrementing, with the processing device, a counter and saving a value of the counter in the database responsive to outputting the part responsive to determining that the part should not be measured and iteratively returning to the receiving operation to receive another part at the metrology tool when another part is provided, wherein the C wherein applying the test rule logic further comprises for the identified part type: providing a first C measuring every n measuring every m measuring every part in response to determining that the part should be measured when C wherein z<x<y, 1<m<n, and m and n are integers and C
