ALD-MCP containing no lead

ALD-MCP containing no lead

By reviewing all materials starting from scratch and applying an ALD* (atomic layer deposition) technique, we succeeded in creating ALD-MCPs (microchannel plates) that ensure low noise and high signal multiplication (gain) without using materials containing lead. Eliminating lead is great step forward because its use is restricted in the RoHS directive issued by the European Union (EU) as a hazardous substance. The ALD-MCP is likely to replace currently used MCPs that contain lead and will serve as a high performance MCP useful for mass spectrometers and scanning electron microscopes (SEM). We will start supplying samples of ALD-MCP for evaluation from October 1st (Thu), 2020 aiming to sell them as commercial products next spring.


* ALD: Abbreviation of Atomic Layer Deposition. This is a thin-film deposition technique capable of precisely controlling the thin-film thickness and structure by forming atomic layers one by one and is widely applied in the manufacture of semiconductor devices.
