APPARATUS AND METHOD FOR SEMICONDUCTOR PACKAGE FAILURE ANALYSIS

摘要

A pulsed laser apparatus for milling a sample is described. The apparatus includes a pulsed laser, a scan head for scanning a beam from the pulsed laser across the sample and an F-theta lens for focusing the scanned beam onto the sample. The apparatus may also include a liquid bath for milling the sample under the liquid, such as water. Methods of pulsed laser milling are also described.
