The CIQTEK DB550 dual-beam FIB-SEM brings together high-resolution electron imaging and precision ion beam processing on a single platform. CIQTEK has validated its DB550 Focused Ion Beam Scanning Electron Microscope (FIB-SEM) on real 5nm process node chip samples, demonstrating production-ready TEM sample preparation with intact fin structures, zero amorphization, and clearly resolved film layers. The results confirm that the DB550 meets the exacting demands of advanced semiconductor failure analysis labs working at the cutting edge of process technology. In advanced chip research and manufacturing, two tools matter above all others. The Transmission Electron Microscope (TEM) lets you see structures at the atomic scale. But before you can look, you need a sample thin enough for electrons to pass through. That is where the dual-beam FIB-SEM comes in. It is the precision workshop that prepares those ultra-thin specimens. Meet the DB550: One Platform for Imaging and Nanoscale Processing The CIQTEK DB550 FIB-SEM integrates two powerful capabilities onto a single platform. On one side, a scanning electron microscope (SEM) delivers high-resolution surface imaging. On the other, a focused ion beam (FIB) performs nanoscale material removal with surgical precision. Together, they bridge the gap between observation and fabrication at dimensions measured in billionths of a meter. At the heart of the DB550 sits a low-voltage, high-resolution electron column paired with CIQTEK's proprietary "Chengying" ion column, developed entirely in-house. The Chengying column is the engine behind the system's nanoscale cutting and etching capabilities. CIQTEK controls the full design and manufacturing pipeline for this critical component. The 5nm Challenge: Why Sample Preparation Gets Harder at Every Node At 5nm and below, chip architectures rely on fin-type field-effect transistors (FinFETs) with fin widths and pitches measured in just a few nanometers. The DB550 is designed to handle the full sample preparation workflow for these demanding process nodes. It starts with high-current rough cutting to quickly remove bulk material and reach the target region. Then it transitions to low-voltage fine polishing to thin the sample to TEM-ready dimensions without damaging the delicate structures underneath. TEM Validation: The Proof Is in the Image CIQTEK prepared a 5nm process node chip sample on the DB550 and transferred it to a TEM for characterization. The results speak for themselves. TEM characterization of a 5nm chip sample prepared on the DB550 shows intact fin structures with clear, well-defined film layers and no amorphization damage. The TEM images revealed that the fin structures remained completely intact after FIB preparation. There was no detectable amorphization in the silicon crystal lattice. The individual film layers appeared clear and sharply defined in the TEM cross-section. These results validate the dual-beam sample preparation performance of the DB550 on...

  A Winning Team: SEM + FIB, the "Golden Combination"   CIQTEK brings SEM and FIB together as a powerful team, providing critical support for PCB process optimization, reliability verification, and root cause determination of failures. SEM High-Resolution Imaging: The "Microscope" for Surface Details The SEM uses a high-resolution electron beam to capture crisp images of PCB surface morphology. It reveals solder pad plating, intermetallic compounds, micro-cracks, tin whiskers, and foreign particle contamination with exceptional clarity. Coupled with energy-dispersive X-ray spectroscopy (EDS), the SEM also performs elemental analysis on microscopic regions. This combination lets engineers identify the chemical signature of defects, making it straightforward to spot issues like short circuits, open circuits, corrosion, and plating anomalies. FIB Nanoscale Cutting: The "Scalpel" for Internal Structures While the SEM excels at surface imaging, the FIB takes over when you need to see what is happening inside the board. Using a nanometer-precision ion beam, the FIB performs targeted cross-sectioning at the exact defect location. It prepares ultra-thin slices through multi-layer boards, blind vias, and buried vias, exposing internal structures that mechanical sectioning simply cannot reach. Think of the FIB as a microscopic surgical tool. It removes material with nanometer accuracy, leaving a clean cross-section ready for imaging and analysis.   CIQTEK Semiconductor Showcase: See It in Action   The Beauty of the Microscopic World, Revealed in Every Detail.
