Patent ID: 7729795

Claim:
A method of verifying a Site-Dependent (S-D) wafer comprising: receiving a first S-D wafer using a Non-Site-Dependent (N-S-D) transfer system; transferring the first S-D wafer to a first S-D processing element using the N-S-D transfer system; creating one or more unverified S-D wafers, wherein one or more S-D unverified evaluation features are created at one or more sites on a first S-D unverified wafer using a first S-D creation procedure; determining a first S-D evaluation wafer using the one or more unverified S-D wafers; transferring the first S-D evaluation wafer to a first S-D evaluation element using the N-S-D transfer system, or a Site-Dependent (S-D) transfer system, or a combination thereof; establishing first confidence data for the first S-D evaluation wafer using a first S-D evaluation procedure, wherein a S-D unverified evaluation feature at a first site on the first S-D evaluation wafer is evaluated; comparing the first confidence data for the first S-D evaluation wafer to first confidence limits; identifying the first unverified evaluation feature as a high confidence feature having a first level of confidence associated therewith and identifying the first S-D evaluation wafer as a high confidence wafer having the first level of confidence associated therewith, when a first confidence limit is met; and applying a first corrective action when the first confidence limit is not met.
