The Celero PL system utilizes a laser-based phase detection and imaging capability that leverages custom optics and image processing algorithms to enable best in class throughput and sensitivity for silicon carbide and gallium nitride-based materials on 100mm to 300mm wafer sizes. Leveraging multiple light sources and sensor channels, the system can detect, measure and image a broad variety of subsurface crystalline defects, associated with bulk wafers and epitaxial layers, surface particles, scratches, pits, surface contamination, stains, point or bulk wafer stress, voids/inclusions, including chips and cracks at the edge of the wafer.

As panel-level-packaging (PLP) transition from copper-clad laminates (CCL) to glass, the industry must adapt to ensure starting substrates are free of killer defects and contamination or latent defects that may result in yield loss or scrapped panels at later stages in the process flow. The PrimaScan P system is specifically designed to address incoming glass panel quality control for both the advanced IC substrate (AICS) and fan-out panel level processing (FOPLP) segments.

The PrimaScan P system delivers unique laser-based scanning and imaging via proprietary optics and sensing technologies for the reliable inspection of nanometer sized defects for either R&D or high-volume manufacturing environments. Utilizing multiple channel inspection technologies, the system can detect, measure and image surface particles, scratches, pits, surface contamination, stains, film or bulk panel stress, voids/inclusions, including chips and cracks at the edge of the panel.

The PrimaScan R&D system offers a smaller spot size and higher pixel resolution than its high volume production counterpart tools. The flexibility in sample handling options combined with the multiple sensing channels and higher resolution imaging makes this the ideal tool for R&D and lab environments. Similar to the other tools in the PrimaScan line, the PrimaScan R&D system offers reliable inspection of nanometer sized defects on a variety of opaque and transparent/semi-transparent substrates and samples suitable for either R&D or lab environments. The system can detect, measure, characterize and image surface particles, scratches, pits, bumps, surface contamination, film or bulk wafer stress, voids/inclusions, including chips and cracks at the wafer edge.

Designed with versatility in mind the PrimaScan R&D system can handle a variety of wafer sizes and substrate types including film frame, photomask and sample tray.

The Class 1 certified EB40 module offers combined edge and backside inspection and is also available as separate edge (E40) and backside (B40) modules. These modules provide brightfield and darkfield inspection to detect defects on the entire bevel and backside, covering Zone 1 to Zone 5. This enables faster root-cause analysis of defects that can migrate to the wafer interior, impacting die yield.

The EB40 module captures defect images on the fly, creates whole-wafer composite images, and integrates with SEM bevel review. All inspection and metrology results, including defect, whole wafer and SEM images can be analyzed together in a single database using Discover Defect software. Correlating EBR metrology with defectivity data, SEM data and micro-inspection results is just the beginning of what Discover software can do. In addition to advanced on-tool defect binning, real-time edge ADC classification can be assigned to defects prior to manual offline review using Discover Review software.

The Firefly G3 platform offers multiple imaging modes, including Onto Innovation’s patented Clearfind® Technology, a technique to detect residue defects on metal and metal defects on organic layers. The combination of high sensitivity inspection, 2D/3D metrology and on tool color image capture capability in a single platform reduces capital investment requirements and provides a reliable pathway for panel-based process applications that require high I/O counts and multiple-chip integration.

Integration with Onto Innovation’s Discover® Defect and TrueADC® software quickly turns defect data into actionable process control, improves defect classification and reduces manual review. It enables our customers to develop, learn and analyze new processes reliably while significantly improving their product delivery time to market.

The Dragonfly G3 is a widely adopted pattern inspection system that utilizes line scan imaging technology to deliver fast, sub-micron defect detection for both R&D and high volume manufacturing environments. It features multiple illumination channels, including brightfield, darkfield, high-speed IR for embedded defects, and Clearfind^® technology for detecting non-visual organic residues. Powered by modern machine learning algorithms, the Dragonfly G3 system offers a complete on-tool solution for defect detection, nuisance reduction and classification.

The system offers additional flexibility through the integration of multiple 3D metrology capabilities, including film thickness and structural profiling, and substrate thickness measurement. It features the latest 3Di^™ technology, delivering and precise bump height metrology. The Dragonfly G3 system, with optional edge and backside inspection via the EB40 module, offers a comprehensive all-surface inspection solution for both front-end and back-end OQA.
