Today’s ribbon cutting is delivering on Team Michigan’s commitment that Michigan’s economic recovery is experienced by all 10 million plus of our friends and neighbors.”

SK Siltron CSS Background

SK Siltron CSS, headquartered in Auburn, Mich. (Bay County), announced plans in August 2021 to expand production of much-needed silicon carbide wafers, considered the future of the industry because of their ability to efficiently transfer energy. The company acquired and rehabilitated a facility in Monitor Township, near Bay City, to support its growth. 

The project is expected to result in the creation of up to 150 jobs and was supported by a $1.5 million Michigan Business Development Program performance-based grant. Michigan was chosen for the project over sites in Georgia, North and South Carolina, Tennessee, and Texas for its talent and proximity to automakers.

The project will result in high-wage jobs in high-tech manufacturing ranging from semi-skilled operators to engineers, and will continue to strengthen Michigan’s automotive, mobility and advanced manufacturing industries. The semiconductor industry already contributes $4.6 billion in total gross regional project for the state of Michigan, with Michigan among the top states in the nation for semiconductor manufacturing. Adding the new jobs and this significant investment by SK Siltron CSS in Michigan solidifies the company’s presence and creates a stronger path toward future investment here in the state.

The demand for power semiconductors is rapidly increasing as automakers enter the electric vehicle market and telecommunication companies expand 5G capabilities. SK Siltron CSS manufactures a specialty wafer made of silicon carbide (SiC) that can be used in electric vehicles. SiC wafers are more efficient at handling high powers and conducting heat than normal silicon. When used in EV system components, this characteristic can allow a more efficient transfer of electricity from the battery to the motor, increasing the driving range of an EV by 5 to 10 percent.

Michigan Competes for Semiconductors 

In the past year, Michigan has secured bold investments in semiconductor and polysilicon manufacturing.  Bringing this critical chain home, from China to Michigan, will cut down on costly productions delays, make businesses more efficient, and ultimately pass savings on to consumers.

  • Hemlock Semiconductor, a leading provider of high-purity polysilicon products for the electronic and solar power industries, onboarded over 400 full-time employees in Hemlock.   
  • KLA, a global semiconductor firm, opened their headquarters in Ann Arbor creating 600 good-paying jobs.  
  • Wacker, a chemical and polysilicon firm, opened a cutting-edge innovation center in Ann Arbor creating 300 good-paying jobs.  
  • SK Siltron, a semiconductor wafer manufacturer, announced a new facility near Bay City, creating 150 good-paying jobs.  
  • Calumet Electronics, one of a few American manufacturers producing organic substrate components for microelectronics, announced an expansion creating 80 jobs in the Keweenaw Peninsula. 

Creating Opportunity in Bay City

“Bay County has played an acclaimed and key role in the storied history of the automotive industry in the state of Michigan.  This significant investment and commitment by SK Siltron CSS reinforces that legacy and ensures that our community and state will continue to be at the forefront of mobility, technology, and ingenuity, now and well into the future,” said Trevor Keyes, President and CEO, Bay Future, Inc. “SK Siltron CSS is a world class, high technology, company that could have chosen to invest anywhere in the world, and chose Bay County, Michigan. We are appreciative that they decided to choose to invest here and are thankful to all of those who assisted in making this project a reality.”

SK Siltron CSS will work with local partners to train workers, focusing on critical initiatives to reskill and upskill workers for the sustained growth of the region. Specifically, SK Siltron CSS is proud to partner with Delta College through the Michigan New Jobs Training Program to support training in the skills needed for success in SiC wafer manufacturing. 

Working closely with Delta College, SK Siltron CSS is developing specific content to support the skills needed for employment while demonstrating its commitment to helping prepare Michigan workers for careers in advanced manufacturing. Moreover, by making these opportunities available to employees at all levels, SK Siltron CSS is committed to advancing the careers of current employees and supporting their professional development.

Governor Whitmer’s CHIPS and Science Act Executive Directive

The CHIPS and Science Act will fund $52 billion in incentives to boost domestic semiconductor production and research, $2 billion of which would be dedicated to incentivizing production of the “mature node” semiconductors used by automakers and parts suppliers. Mature node chips are also used in medical devices, agricultural machinery like farm tractors and combines, as well as radiation-proof chips required by our national defense industrial base. 

In early August, Governor Whitmer signed an executive directive instructing state departments and agencies to leverage incoming resources from the CHIPS and Science Act as effectively and efficiently as possible. The directive furthers collaboration with the MEDC to continue attracting long-term, sustainable investments from semiconductor companies around the world. Additionally, it instructs departments and agencies to identify opportunities for workforce development geared towards the needs of the semiconductor industry, including adapting existing programs, collaborating with higher education institutions, and providing targeted education and training with additional federal resources. Finally, it urges efficient approval of any permits, applications, or requests from the state to avoid duplication or delay. 

The directive will help increase domestic chip production near automakers and spur innovation, reduce inefficiencies, and avoid costly delays. By securing a robust semiconductor supply chain—anchored by SK Siltron CSS, Hemlock Semiconductor, KLA, and Calumet Electronics—Michigan will keep attracting long-term, sustainable investments from companies around the world and bring supply chain home.
