Vishay Intertechnology Receives Research Grant for Silicon Laser Annealing

Vishay Intertechnology

MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) announced that the company’s facility in Borgaro Torinese, Italy, recently received a research results R&D grant from the European Union and the Regional Government of Piedmont for its Silicon Laser Annealing (SiLA) project. The project will focus on the study and development of advanced low-temperature processes to locally and selectively control the energy transferred to chips during fabrication.

The automotive market sector is continually increasing the efficiency of full-electric engines, which is driving the definition of new design rules for their electronic components. As a world leader in power semiconductors, Vishay’s goal is to meet the need for advanced 600 V to 1200 V diodes, IGBTs, and MOSFETs for electric (EV) and hybrid electric (HEV) vehicles. With the SiLA project, the company will apply thin wafer technology to its FRED Pt® fast recovery diodes to improve their electric and thermal behavior, and to guarantee efficiency improvements for energy conversion in battery chargers and motor controls for powertrains. This will allow for a further acceleration of new device adoption in the e-mobility market.

The main objectives of the SiLA project are to study and develop laser annealing technology to obtain: thermal dissipation improvements, reduced energy losses from conduction and switching, increased roughness in dynamic conditions, and a definition of new technological processes based on scientific activities fully developed in the Piedmont area. A project partner specializing in power lasers will share different laser sources and its know-how to realize an engineering laser system. All activities will be used as milestones and baselines to support the development of a new Vishay diode family and fabrication process.

Funding for the SiLA project (codes 337- 296 and 338- 296) grant was provided through Regional Operational Program (ROP) ERDF 2014-2020, Axis1, Act. I.1b.1.2 PRISM-E Call 2018 to support, in synergy with local partners’ R&D efforts, activities for developing new technologies.
