Abstract Several methods are used to invert samples 180 deg in a dual beam focused ion beam (FIB) system for backside milling by a specific in-situ lift out system or stages. However, most of those methods occupied too much time on FIB systems or requires a specific in-situ lift out system. This paper provides a novel transmission electron microscopy (TEM) sample preparation method to eliminate the curtain effect completely by a combination of backside milling and sample dicing with low cost and less FIB time. The procedures of the TEM pre-thinned sample preparation method using a combination of sample dicing and backside milling are described step by step. From the analysis results, the method has applied successfully to eliminate the curtain effect of dual beam FIB TEM samples for both random and site specific addresses.

Abstract Frontside die inspection by Scanning Electron Microscopy (SEM) is critical to investigate failures that appear dispersed over the GaN die surface and that will be very difficult to localize by the typical Focus Ion Beam (FIB) or Transmission Electron Microscopy (TEM) analysis. Frontside sample preparation is; however, extremely challenging if the device was already subjected to sample preparation for backside Photo Emission Microscopy (PEM). In this paper, a novel sample preparation method is presented where all front side layers are removed and only the 5μm GaN die is left for inspection.

Abstract This paper demonstrates a novel method of XTEM sample preparation for site-specific surface defect analysis using backside polishing. Analysis of three different types of site-specific surface defects was demonstrated using a novel backside XTEM sample preparation method. The details of the backside XTEM sample preparation method and some examples are reported in this paper. Comparing to Auger electron spectrometry (AES) results on similar defects, more detailed and precise information is observed using TEM analysis with this method. It is therefore a complementary technique to traditional AES analysis on surface defects for contamination with atomic level concentration. From the results, the sample preparation method can produce a clean, pristine surface that is well characterized and could be reproduced, successfully.

AbstractA rapid and precise sample preparation method using focused ion beam (FIB) etching was developed for cross-sectional transmission electron microscopy (X-TEM) analysis of a thin-film transistor (TFT) fabricated on a glass substrate. Gallium (Ga) ions accelerated at 30 kV and at various incident beam angles were applied during FIB etching to create a uniform thin wall. We successfully prepared X-TEM specimens of long and fragile aluminum (Al) whiskers formed on thin Al films in TFT metallization, where a strong charge is built up during FIB etching. The effect of ion-beam-assisted tungsten deposition prior to FIB etching is discussed. A whisker having a length not exceeding approximately 10 #x00B5;m can be successfully etched to a thickness of 200 nm while keeping its original shape. The performance of this technique is demonstrated in applications to etching at other fragile locations related to TFTs.

Abstract An experimental setup is presented, that allows in-situ Transition Electron Microscopy (TEM) investigation of void formation and growth within fully embedded interconnect structure, as a response to an external bias. A special TEM holder is employed to perform in-situ I-V measurements across the Via, simultaneously monitoring the morphological and chemical changes surrounding the void. This work presents in detail a Focused Ion Beam (FIB) based sample preparation method that allows the analysis of a Cu single Via structure found in the advanced microelectronic 14nm FinFET technology, as well as preliminary TEM observations.
