Preparations that make a difference - MO Precursors

To produce pure, perfectly reliable, and exact LEDs, the fundamentals have to be right. Our high-purity metalorganic precursors and dopants offer batch-to-batch uniformity, for producing high-quality LEDs.


Deposition precursors

When customers take reliable delivery of our bubblers, they know that what sound like children’s toys are actually crucial containers for one of the most important foundations of their LED solution: our pure precursors. 

Our bubblers come in a variety of sizes and the precursors they become contain the elementary unit of the microscopic layers of an LED. In case you’re wondering how this works, precursors help create fundamental building blocks of an LED. Each layer is added gradually in a special evaporation chamber (or epitaxy chamber). As our precursors come into contact with the heated base (the LED wafer), they leave deposits – and ultimately, it’s these tiny deposits that become semiconductors in LEDs and emit light.

You can choose between solid and liquid materials to find the best solution for your needs. We offer a wide choice of bubblers to ensure material transfer is secure, quick and 100% reliable. 

We’ve also spent decades perfecting our logistical and transportation systems to ensure every delivery of pure materials is kept safe and sound, even before you start making preparations for the epitaxy chamber. Regional I&A support is part of the package you buy from us.
