Raymond D. “Ray” Zinn is an inventor, entrepreneur, investor, angel, bestselling author and the longest serving CEO of a publicly traded company in Silicon Valley. He is also the founder of a nationally launched ZinnStarter program at colleges around the country, providing the financial and mentoring support for students to launch new products and companies. In 2015, Ray published his first book, Tough Things First, with McGraw Hill. The book covers Zinn’s analysis of his nearly 40 years at the helm of Micrel, a Silicon Valley institution along with the critical factors that entrepreneurs and seasoned executives alike need to know, including the intricacies of nurturing corporate culture, how to make every employee (and every human) feel valued, the impact and limitations of policies and procedures, and how to manage growth. Zinn is also known for conceptualizing and in effect inventing the Wafer Stepper, and for cofounding semiconductor company Micrel (acquired by Microchip in 2015), which provides essential components for smartphones, consumer electronics and enterprise networks. He served as Chief Executive Officer, Chairman of its Board of Directors and President since the Company’s inception in 1978. Zinn led Micrel profitably through eight major downturns in global chip markets, an impressive achievement. Many chip companies weren’t able to make it through one downturn and very few have survived through all the major downturns. Micrel has been profitable from its very first year, aside from one year during the dot-com implosion. Ray Zinn holds over 20 patents for semiconductor design. He has been mentioned in several books, including Jim Fixx’s The Complete Book of Running and Essentialism by Greg McKeown.
