The US$500 billion inventor
Materials scientist and physicist Dr Tuomo Suntola, who recently won the Millennium Technology Prize 2018 for his invention of atomic layer deposition (ALD), will be participating in the Global Young Scientists Summit (GYSS) 2019 in Singapore, 20-25 January 2019. From laptops to smartphones, many of the electronic devices that we take for granted today would not have been possible without the work of Finnish materials scientist and physicist Dr Tuomo Suntola. In the early 1970s, Dr Suntola developed a way of producing ultra-thin films, one atomic layer at a time that can be used to coat the surface of any material. This technique, called atomic layer deposition (ALD), has been used to improve the performance of computer chips, create high-efficiency solar power cells, and even protect coins and telescope mirrors. It also enabled modern nanometre-scale integrated circuits, which are essential components in virtually all-modern computers and smartphones, and many other electronic equipment. Today, the market value of consumer electronics that rely on the technique exceeds US$500 billion (S$684.5 billion). For his far-reaching work, Dr Suntola was awarded the biennial Millennium Technology Prize, considered the Nobel Prize of technology, in 2018. Dr Suntola, who will be a speaker at the Global Young Scientists Summit (GYSS) 2019, to be held in Singapore from 20 to 25 Jan, said that ALD could also play a key role in creating the next generation of batteries for electric vehicles and other products. “It can also be used for the manufacturing of new materials with as-yet unknown properties,” he said. A serial inventor Even as a child, Dr Suntola was interested in technology. He built wooden miniature replicas of World War II fighter planes, his first transistor radio at the age of 12 when the first transistors became available in Finland, and graduated to constructing radios […]
