QuickOCT-4D

Non-Contact 4D Surface & Thick-Film Profiler

Combining a single-point, visible-light, spectral-domain optical coherence tomography (SD-OCT) sensor with a high-speed, nanometer-encoded X/Y/Z motion-control stage, the QuickOCT-4D can capture the plane of each layer within transparent film samples in a single measurement, at up to 66 kHz. The QuickOCT-4D penetration depth (up to 100µm) and axial resolution (5nm) is optimized for the measurement of multi-layer transparent films, flat substrates, and functional layers in the semi-conductor, life science and pharmaceutical industries. Ideal applications include the measurement of patterned photoresist (or similar transparent coatings) on a silicon, GaAs or glass wafer for backend semiconductor, advanced packaging, display, LED, VCSEL and MEMS as a quality control post-develop and pre-etch.
