Mr. Jeffrey Gum has 15 years of experience in the Silicon Carbide and Silicon (Photovoltaics & Semiconductor) markets as an Engineer, Sales Director, and strategic consultant. Mr. Gum obtained a degree in Chemical Engineering from Montana State University and spent the first five years of his career working as a Nuclear Engineer. From there, he was hired by GT Advanced Technologies (GTAT), to lead R&D efforts in more efficient ways to make polysilicon, a pre-cursor material used in photovoltaic cells and semiconductor wafers. In 2016, GTAT pivoted to become a producer of Silicon Carbide substrate materials, and Mr. Gum took a leadership position as the Director of Global Sales until GTAT was acquired by onsemi in 2021. He now is employed by Hardinge, Inc., a multi-national machine tool builder and is responsible for new product / business development for advanced material markets with an emphasis on the semiconductor industry.
Hardinge, Inc. has over 130 years of experience in machining materials of all types. This presentation will address how a global, well-established machine tool company with deep-rooted application engineering expertise created a highly innovative solution for processing SiC as grown boules into wafer ready pucks. A comparison of this innovative solution (BoulePro 200AX) to the current market practice will be discussed and the cost benefits to this solution will be presented. While the emphasis for this topic is specific to SiC for semiconductor applications, alternate materials and processes that could benefit from a similar solution will be explored.
