Wafer inspection with, for example, high-tech yellow light or green light lamps does not involve UV radiation. Therefore, they not only serve as a replacement for UV lamps, but they also make the use of mercury vapor lamps unnecessary. In the SLEX series you will find 6 different versions. In addition to 3 different types of white light, we also offer lamps with green light, yellow light and orange light. All LED lights differ mainly in terms of color temperature. All versions are also available as filtered models. Equip yourself now with our wafer inspection lamps and achieve overwhelming results directly.

Why to use filtered Slex lights from SECU-CHEK for wafer surface inspection?

• High process reliability is necessary in wafer production
• economically efficient and trouble-free testing operation is desired
• a Solid wafer testing is crucial for the further cost-intensive steps of wafer preparation and chip production
• professional solution according to industry standards required

Reduce waste and increase your ROI by ensuring high-quality output: We offer customized, robust and low-maintenance LED lamps specifically designed for optical wafer inspection. Thanks to the very clear error display, our wafer inspection lamps ensure your process reliability – and enable your company to save enormous amounts of energy during day and night operations. compared to mercury vapor discharge lamps.

Benefit from our Magic Arm wall mount complete set and enjoy the advantages of our high-quality equipment. This has been specifically manufactured for testing with UV LED lights and can be customized to suit customer requirements. Simply send us a convenient request.

Wafer testing can be differentiated between manual testing and manual-optical testing. When testing manually, you have a strong, extremely even and shadow-free illumination. In terms of the required intensity, this offers many advantages over automated wafer inspection. Manual testing is also ideal for visual follow-up inspection of sorted wafers. The manual-optical inspection guarantees a easy integration of visual inspection into the wafer manufacturing process. It ensures a high level of flexibility with a high error detection rate.

Yellow filter and green filter for perfect optical visual inspection

• Robust yellow light lamp housing for continuous operation during wafer inspection
• Easily replaceable filter disk on the wafer lamp
• UV wafer lamp optionally with active fan cooling for a particularly long service life

Improve the wafer production with manual wafer inspection

• Yellow light lamp for wafer inspection: emits in an optimized wavelength range, including the wavelength of 546, 577 and 579 nm, which is typically emitted by mercury vapor discharge bulb-based inspection lamps as the peak wavelength
• yellow better than green (525 nm) for high-contrast detection
• no flickering during wafer testing
• Dimmable yellow light lamp that allows the intensity to be adjusted to the best level for all types of inspections and types of defects
• Semiconductor wafer inspection lamp
• LED-based replacement for common yellow light lamps

Which types of wafers can be inspected with the SECU-CHEK yellow light lamp?

• wafer inspection in semiconductor and chip manufacturing
• wafer testing in photovoltaics
• inspection and analysis of the surface of epitaxy wafers (EPI wafers) and SOI wafers
• visual wafer inspection for bare, thinned and fan-out and strongly curved wafers (eLWB, etc.)
• inspection of crystalline silicone wafers (UV lamp)
• inspection of SEMI standard wafers
• inspection of gold wafers
• quality check of bonded wafers/wafers on tape
• optical testing of monocrystalline wafers and also polycrystalline wafers
• visual test of the surface of silicone wafers
• testing of raw wafers and structured wafers
