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

This project allowed Aymont Technology the ability to take its proven, novel process for smaller diameter silicon carbide crystal growth (2 inch) and expand this to 5-inch crystals. Aymont designed, assembled, and tested its innovative crystal growth reactor to grow and characterize a silicon carbide, 4H single crystal boule.


The novel process gives a higher yield of SiC wafers at a lower cost. These wafers will then be sold to companies, such as GE Global Research, to produce the next generation of Metal-Oxide Semiconductor Field-Effect Transistors, (MOSFETs) to be used in AC motor drives, wind power, and other industrial applications. The implementation of silicon carbide MOSFETs in AC motor drives alone has the ability to save 50 trillion Btu for industrial businesses located in New York. The ability to provide this type of wafers as the starting material for semiconductor device manufactures will help lay the groundwork for New York to play an integral role in the power electronics revolution.

Project Results

This crystal growth technology will allow Aymont Technology to further increase the output of 4H crystals to meet the demands of an every expanding market. This project has helped to lay the groundwork for a potentially huge energy savings for New York businesses as well as other companies globally. Silicon carbide provides more efficient power switching than existing silicon power devices in wind power, hybrid and electric vehicles, and industrial motor drives. A 1 – 2% increase in inverter (AC motor drive) efficacy has been demonstrated with the use of silicon carbide. This in turn equates to a 10 – 20% reduction in the amount of energy required to operate these drives. The use of silicon carbide along with other electronic packaging and new technologies for inverters will reduce the electrical power consumed in New York from existing manufacturing users by 10%, or 50 trillion Btu. The silicon carbide market is currently growing rapidly. Aymont has estimated that it will add roughly 70 additional high-paying technology jobs in Saratoga County in the next few years due to growth in market share.
