Tuomo Suntola

Tuomo Suntola, PhD in Electron Physics (1971), has far-reaching academic and industrial career comprising pioneering work from fundamental theoretical findings to successful industrial applications. He is the father of the Atomic Layer Deposition (ALD) technology which is an enabling technology for nanoscale semiconductor device manufacturing. Beside his industrial research he was searching for a holistic perspective to the physical reality – which, in mid 1990s, crystalized to the Dynamic Universe approach allowing the study of the universe as a dynamic energy system with the energies of gravitation and motion in balance.

 

BIOGRAPHY

Tuomo Suntola graduated MSc (1967) and PhD (1971) in Electron Physics in the Electrical Engineering Department at Helsinki University of Technology. He entered to materials sciences and thin film technologies by solving the late 60’s mystery of the nanosecond switching mechanism in “Ovonic” thin film devices as his doctoral dissertation. His first industrial work was “Humicap®” thin film humidity sensor for Vaisala Oy (1973) which still, almost 40 years later holds the world market leader’s position in humidity sensing. He was invited to Instrumentarium Oy where he in 1974 introduced the Atomic Layer Epitaxy (ALE) process which after development for productional capability in became the leading technology for electroluminescent flat panel displays. After further development at Microchemistry Ltd the ALE technology and machinery reached the requirements for advanced semiconductor processing. Renamed as Atomic Layer Deposition (ALD) the technology has merged into IC manufacturing, enabling extreme conformality and controlled processing of ultra-thin material layers of a few atomic layers. Suntola’s technologist’s career produced many important patents, vital industrial applications, and scientific papers. His technological impact was complemented by work on photovoltaic devices and insightful analyses of global energy challenges.

“Considerations of the philosophy of science and the foundations of physics have been a source of inspiration throughout my career, both in technological developments and the search of a holistic view of physical reality".
