Patent ID: 8455821

Claim:
A method of processing a semiconductor wafer, comprising: assigning the semiconductor wafer a wafer ID; selecting a process recipe for the wafer, said process recipe including positional data for one or more sample sites to be analyzed; loading the wafer into a charged particle beam system, said charged particle beam system to process the wafer according to the selected process recipe values; navigating to each sample site using said positional data; imaging each sample site; milling the wafer surface on either side of each desired sample location leaving a thin layer of material; transferring the one or more samples to an ex-situ lamella extraction device, said device importing recipe values including positional data for each sample site; extracting the one or more samples from the wafer using said recipe values wherein extracting the samples from the wafer comprises placing the wafer with the one or more samples to be extracted on a moveable stage, the samples being physically attached to the wafer; moving a microprobe into contact with the one or more samples, the microprobe comprising a hollow tube connected to a vacuum source and open at the microprobe tip; applying a vacuum through the microprobe tip so that the vacuum holds the one or more samples against the microprobe tip; lifting the microprobe with attached one or more samples away from the wafer, severing the attachment of the wafer and the sample; moving the microprobe so that the one or more samples is in contact with a desired position on a sample holder; moving the microprobe away from the released sample; transferring the one or more samples to a TEM system, said TEM importing recipe values for each sample and said TEM also processing the one or more samples according to the values specified by the recipe, said processing including imaging the samples and analyzing the images; imaging the one or more samples with the TEM; analyzing the TEM images to determine a feature dimension for the one or more sample sites; and adjusting the positional data or fiducial mark locations at additional sample sites in response to the determined dimension.
