Umicore’s business unit Precious Metals Chemistry has opened an innovative production unit for advanced metal organic precursor technologies used in the semiconductor
markets, respectively TMGa
(trimethylgallium) and TEGa
manufacturing process is innovative and unique. It offers a more sustainable and ecological production method by minimising hazardous side streams and material losses and optimising yield to nearly 100 percent. This makes it superior to all existing manufacturing methods in the industry.
“I am proud that this patented innovation has now become a world-class and industrial scale manufacturing plant. It will provide benefits for our customers and the environment and underlines Umicore’s position as a pioneer in sustainable technologies,” said Dr Lothar Mussmann, vice president of Umicore
Precious Metals Chemistry.
Precious Metals Chemistry is the only European manufacturer of TMGa
and supplies customers across the world from its Hanau manufacturing base. Umicore
Precious Metals Chemistry helps to reduce cost of ownership through its innovative approach to process chemistry and its collaborative approach with customers and end users.
is a colourless liquid with very high vapour pressure, which boils at low temperatures. Umicore’s new production process increases the yield of TMGa
in comparison with current production technologies. In this way, organic solvents can be completely dispensed with. The TMGa
is prepared by chemically reacting gallium trichloride with a more efficient methylating agent in molten salt. This reduces the amount of waste per kilogram of TMGa
by more than 50 percent, with the resulting intermediates being recycled in the process. The finished product is then used in the semiconductor
industry, where it evaporates in closed systems onto a substrate. This creates, for example, environmentally friendly LED
