Mustafa Pinarbasi, Ph.D., Chief Technology Officer and Senior Vice President of Magnetics Technology

Mustafa Pinarbasi is a pioneer and innovator in magnetic thin films. Dr. Pinarbasi spent the first 18 years of his career at IBM and Hitachi Global Storage Technologies (GST) (formerly IBM, now part of Western Digital) as a leading technologist in magnetic materials and thin films. At IBM, Dr. Pinarbasi pioneered the adoption of ion beam sputtering deposition technology, a revolutionary conductor and hard magnet process, by the magnetic head industry. He was recognized with the IBM Corporate Award in 2000 for his work on developing the giant magnetoresistive (GMR) sensors which resulted in the introduction of the first GMR-based hard disk drives in the world. In the same year he was named as an IBM Distinguished Engineer for his contributions to the thin film magnetic field. Dr. Pinarbasi spent five years at Hitachi GST, where he led the development of tunneling magneto-resistance (TMR) read head processing used in hard disk drive products.

He most recently was Chief Technology Officer at SoloPower, a thin-film solar company, where he built a comprehensive technology team, developed roll-to-roll thin film photovoltaic deposition processes and equipment, and spearheaded the industry’s first flexible and light weight CIGS (Copper Indium Gallium di-Selenide)-based solar modules that are certified to both U.S. and European standards. He is an inventor with over 190 U.S. patents, with several in thin film magnetic materials and processing, spin valve sensors, magnetic tunnel junctions, nanostructures and photovoltaic cells. He has authored or co-authored over 30 scientific publications in thin film materials, magnetic multilayer structures, processing, tooling, product development and reliability. During his career, he has been the recipient of numerous awards including the Gold Patent award at Hitachi GST and Outstanding Technical Achievement and Outstanding Innovation awards at IBM. Dr. Pinarbasi holds a Ph.D. in Materials Science and Engineering from the University of Illinois at Urbana-Champaign.
