Richard Mee

Richard Mee is the CEO of Tier 1 Silicon. Richard has held several executive leadership positions in the Silicon Wafer industry where he has rewarded shareholders for the past 3 decades by maximizing their value through various company growth strategies. Richard’s career in semiconductor materials began in 1988 working as a process/equipment engineer at Crystaltek, Inc., an east coast silicon wafer reclaiming house that serviced mainly IBM 3.25 in wafers. Moving to San Jose, CA in 1991 to co-found Wafer Reclaim Services, Richard had his first opportunity to startup a reclaim facility from the ground floor that boasted capabilities to reclaim 2-12 inch wafers. Joining SiliconQuest International in 1993 and serving as its President for 15 years, Richard combined wafer reclaim products with wafer brokerage to provide a balanced product offering. Building on the thesis that the market was in need of a wider range of silicon materials products, Richard partnered in 2008 with an investor group to roll up various silicon materials and silicon service companies. These acquisitions included: Wafer Reclaim Services, Techintercept, Montco Silicon, Isonics, and Pure Wafer. During this consolidation Richard held senior management positions including: President CEO, Executive Chairman, and Board member.
