microPREP 2.0 - High-Volume Laser-Based Sample Preparation for Semiconductor and Materials Failure Analysis

3D-Micromac’s microPREP 2.0 enables high-volume sample preparation of metals, semiconductors, ceramics, and compound materials for microstructure diagnostics and failure analysis.

microPREP 2.0 complements existing approaches to sample preparation such as FIB processing. The system is also suited for SEM inspection of advanced-packaging devices, X-ray microscopy, atom probe tomography, and micro mechanical testing.

microPREP 2.0 provides the following benefits:

  • Shorter time to sample: up to 10,000 times faster than FIB
  • Up to an order of magnitude lower cost of ownership
  • High degree of automation due to recipe-based, ergonomic user interface
  • Virtually no structural damage and no elemental contamination by ps laser processing
  • Providing larger-sized samples with micron-level precision

Industrial Femtosecond Lasers for Precision Micromachining

Femtosecond laser micromachining is leading the way in cold-ablation material microprocessing. Femtosecond pulses eliminate unwanted thermal effects in the heat-affected zone (HAZ), while superior peak powers enable machining of various metals, ceramics, sapphire and glass with unprecedented accuracy. Machining precision is enhanced with tighter focused spots (thanks to excellent beam quality and access to shorter wavelengths). Process repeatability and yield is improved with the higher pulse-to-pulse energy stability, and overall throughput benefits from ever-increasing average powers at higher repetition rates.

The PHAROS and CARBIDE laser systems from Light Conversion represent the state-of-the-art in industrial-grade femtosecond laser technology, combining high average powers (up to 40W) with sub-190fs pulses and market-leading energy stability of 0.5% RMS. Fully integrated harmonics modules are also available for wavelength extensions down to 206nm.

With proven reliability in 24/7 production environments and key applications in drilling, cutting and ablation, existing customers include major manufacturers in display, automotive, LED, and medical devices industries.
