The Workflow for TEM Lamella Preparation

Just do it with high quality at high throughput

Crossbeam offers a complete solution for preparing ultra-thin, high quality TEM samples at high throughput, ready for analysis in transmission imaging mode, in TEM or STEM.

1. Automated navigation to the specimen’s region of interest (ROI)

Begin the workflow without time-consuming search for the ROI
Use the navigation camera on the airlock to locate specimens
The integrated user interface makes it easy to navigate to your ROI
Benefit from the large, distortion-free field of view in the SEM

2. Automated Sample Preparation (ASP) to prepare a lamella out of the bulk

Start the preparation with a simple three-step process: ASP
Define the recipe including drift correction, deposition and coarse and fine milling
The ion optics of the FIB column enables high throughput for the workflow
Duplicate the recipe and repeat as often as required in order to start a batch preparation

3. Lift out

Bring in the micromanipulator and attach the lamella to its tip
Cut out the lamella from the bulk
The lamella is then ready for lift out and can be transferred to a TEM grid

4. Thinning: the final step is crucial, as it defines the quality of your TEM lamella

The instrument’s design allows you to reach a desired thickness of the lamella by enabling live monitoring of the thinning
Use two detector signals in parallel to judge lamella thickness and obtain reproducible end thickness on the one hand (with the SE detector) and to control surface quality on the other hand (with the Inlens SE detector)
Prepare high quality samples with negligible amorphization

Comparison of milling strategies in silicon:

Material removal with conventional milling (left) takes 10 min 54 sec whereas with Fastmill the same amount of material is removed in 7 min 21 sec (right). With Fastmill, a newly-introduced scanning strategy, milling speed is enhanced by optimally exploiting the angle-dependent sputtering effect. Fastmill enables up to 40% faster milling than regular line milling.
