Silicon Carbide Wafers for Energy Efficient Electronics(ST11136-1)

Aymont Technology, Inc.


Silicon Carbide (SiC) is a next-generation semiconductor material now being used for more energy-efficient electronics. Companies worldwide are trying to commercialize SiC electronic power devices for power factor correction in power supplies, AC drives, hybrid electric vehicles, and power handling and distribution. Energy efficiency will drive the anticipated market growth. Success in SiC has historically been limited by wafer size, availability, and cost.

Project Description

Aymont will determine 4H-SiC growth parameters in a large crystal growth furnace. Growth parameters that will be addressed are: exact growth temperatures, temperature gradients, and pressure during growth. These boules will then be sliced and polished to produce wafers. These wafers will be characterized and inspected by Aymont.


The demonstration of 100 mm diameter SiC wafers will have several quantifiable positive effects on New York. First, a possible 10-20% reduction in the amount of energy used in industrial motor drivers and a 40-50% reduction in electrical energy, and second, an anticipated 20% market share of SiC wafer production by 2013 can bring roughly 70 additional high paying jobs into Saratoga County.
