Semiconductors Place Starkville in Every Corner of the World

October 24 — The world’s leading manufacturer of circuit board substrates perfects its product in Starkville at II-VI Advanced Materials.

“If you do some traveling outside of the country, say to China, India or Turkey, and you use your cell phone, there’s a little piece of Starkville inside the cell tower,” said Eric Bowman, the company’s site manager. “Pretty soon you’re going to find a little piece of Starkville in every electric vehicle that Toyota makes.”

Located in the Thad Cochran Research, Technology, and Economic Development Park, II-VI has just doubled its operation. Fifteen additional operators have been hired in the last two months. Four of its five onsite engineers are MSU graduates. He expects to have up to 100 employees in four years.

Bowman says he targets local hires with a preference for WorkKey certified operators accredited through East Mississippi Community College.

Production of a circuit board substrate starts with its growth in a furnace in the Pine Brook, N.J., facility. Its fabrication and preliminary characterization is done there. Then the product moves to Starkville for polishing, final polishing characterization, final cleaning and shipping.

The product is a silicon carbide wafer disc base for semiconductors that is like a very thin piece of glass. It is the first layer in production of an integrated circuit. One 150 mm diameter wafer can hold 300 to 400 computer chips.

Silicon carbide, the second hardest material known to man, is a specialty market for things that must deal with high temperatures. There is less need for cooling, so the components can handle a lot more power. Its durability makes it ideal for defense, space and mobile communication applications.

The downside of its strength is that SiC substrates are hard to manufacture, thus are quite expensive.

As very thin samples were being passed around the room, one broke. “Somebody at that table owes me $1,500,” Bowman quipped. “Actually, it’s okay. This is scrap.”

The corporation began manufacturing two inch wafers in 2002. It has just demonstrated the world’s first 200 mm (7.9 inch) wafer this year.

The former SemiSouth employee noted that he now is expanding operations into his old space in the research park. Bowman has been with II-VI for three years since SemiSouth closed. The current operation is located in Starkville because it originally was supplying the semiconductor manufacturer.

“We’ve performed so well that they keep saying, ‘This process doesn’t really work good in New Jersey; send it to Mississippi to see if they can make it work better,’” said Bowman. “My goal is to have everything from New Jersey down here.”

Just this year, the Starkville plant has ordered $4 million of new equipment. He expects to expand by $17 million in the next two years.

The 10,000 square foot facility is expanding into an additional 5,000 square feet of cleanroom space in the Powe Building. Given the SiC wafer’s minute tolerance, it must be manufactured in an area that is cleaner than a hospital operating room.

A key step in creating a cleanroom is to replace all of the ceiling tiles with High-efficiency particulate arrestance (HEPA) filters. Clean air is pushed down to the air returns in the room’s baseboards.
