But the company's future in MEMS, which has already been extended to microphones, will be based on diversification in process, product and applications, Vigna added.
Vigna, who has presided over ST's entry into the MEMS business and its rise and recent fall in market ranking said that smartphones are still an opportunity for ST despite the fact the ubiquitous inertial component has become highly competitive.
Vigna reckons that ST saw the decline in the motion MEMS business coming as far back as 2011-2012 and moved to differentiate itself with new technologies and components. "Microphones and environmental sensors are two new classes of sensors where we are active strongly today," he is quoted saying. Not only are these opportunities in a more capable smartphone but also in wearables and smart-homes and smart-cities, Vigna reckons.
ST is also well placed in automotive where it is already the number one supplier of MEMS, excepting those supplied for safety applications, he said.
Vigna's tip for a significant next generation technology is piezoelectric thin films which can be used for actuators in things like autofocus mechanisms and inkjet print heads and for microphones (see ST adds piezoelectric MEMS to process portfolio).
"Companies having only one class of sensor do not have a sustainable future," Vigna said in the interview.
