ZEISS Crossbeam

Your FIB-SEM for High Throughput 3D Analysis and Sample Preparation

ZEISS Crossbeam Family

Discovering and Designing Advanced Materials With Ease

Combine imaging and analytical performance of a high resolution field emission scanning electron microscope (FE-SEM) with the processing ability of a next-generation focused ion beam (FIB). You may be working in a multi-user facility, as an academic or in an industrial lab. Take advantage of ZEISS Crossbeam’s modular platform concept and upgrade your system with growing needs, e.g. with the LaserFIB for massive material ablation. During milling, imaging or when performing 3D analytics Crossbeam will speed up your FIB applications.

Learn in this video how the TEM lamella preparation workflow of ZEISS Crossbeam enables Benedikt Müller, University of Tuebingen, and Claus Burkhardt, NMI Reutlingen, to investigate the crystal structure of NanoSQUIDS.

Extract true sample information from your high resolution SEM images using Gemini electron optics.
The Ion-sculptor FIB column introduces a new way of FIB-processing: by minimizing sample damage you’ll maximize sample quality and perform experiments faster at the same time.
When preparing TEM samples use the low voltage capabilities of the Ion-sculptor FIB: get ultra-thin samples while keeping amorphization damage at a minimum.
Within the ZEISS Crossbeam Family, either exploit variable pressure on Crossbeam 350 or use Crossbeam 550 for your most demanding characterizations.
Enhance your in situ studies with Crossbeam laser: the LaserFIB workflow enables you to gain rapid access to deeply buried structures using the femtosecond laser.

ZEISS Crossbeam Laser Workflow

How the LaserFIB Workflow Enhances Your in situ Studies

For in situ studies you need to localize ROIs in 3D, ablate material via a targeted preparation and perform 3D imaging and analytics. Add a femtosecond laser to your ZEISS Crossbeam and benefit from ultra-fast sample preparation.

Watch this animation and discover how the LaserFIB workflow is used on an electronic sample. In this correlative experiment a defect was located non-destructively with XRM. Then the ROI was exposed with the femtosecond laser, fine polished by the FIB beam and finally analyzed with the SEM.

The Workflow for TEM Lamella Preparation

Just do it with high quality at high throughput

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

The Technology Behind ZEISS Crossbeam

SEM Electron Optics

Choose between Two Columns

The FE-SEM column of ZEISS Crossbeams is based on Gemini electron optics as all ZEISS FE-SEMs. Decide on the Gemini VP column of Crossbeam 350 or the Gemini II column of Crossbeam 550.

Field emission SEMs are designed for high resolution imaging. Key to the performance of a field emission SEM is its electron optical column. Gemini technology comes with all ZEISS FE-SEMs and FIB-SEMs: it is tailored for excellent resolution on any sample, especially at low accelerating voltages, for complete and efficient detection, and ease-of-use.

Gemini Optics is Characterized by Three Main Components

The Gemini objective lens design combines electrostatic and magnetic fields to maximize optical performance while reducing field influences at the sample to a minimum. This enables excellent imaging, even on challenging samples such as magnetic materials.
Gemini beam booster technology, an integrated beam deceleration, guarantees small probe sizes and high signal-to-noise ratios.
The Gemini Inlens detection concept ensures efficient signal detection by detecting secondary (SE) and backscattered (BSE) electrons in parallel minimizing time-to-image.

Benefits for Your FIB-SEM Applications

Long-term stability of the SEM alignment and the effortless way it adjusts all system parameters such as probe current and acceleration voltage
Achieve distortion-free, high resolution imaging even over large fields of view with the help of the near magnetic-field free optics
Tilt the specimen without influencing the electron optical performance

Gemini Novel Optics

Profit from Surface Sensitive Imaging

High resolution imaging at low landing energy is required for beam as a standard. It is essential for:

beam sensitive samples
non-conductive materials
gaining true sample surface information without undesirable background signal from deeper sample layers

The novel Gemini optics are optimized for resolutions at low and very low voltages and for contrast enhancement.
Technological characteristics are the high gun resolution mode and the optional Tandem decel.

The high gun resolution mode results in minimized chromatic aberration thanks to of a reduction of primary energy width by 30%.

ZEISS Crossbeam 550 Objective with Tandem decel

Tandem decel optional sample biasing up to 5 kV further improves the excellent imaging capabilities at low voltages.

Tandem decel, now introduced to ZEISS Crossbeam 350/550, can be used in two different modes:

Tandem decel, a two-step deceleration mode, combines the beam booster technology with a high negative bias voltage that is applied to the sample: the electrons of the primary electron beam are decelerated, thus the landing energy is effectively reduced
Apply a variable negative bias voltage between 50 V and 100 V. One application mode enhances the contrast of your images
Apply a negative bias voltage between 1 kV and 5 kV and improve the low kV resolution of your images
