• GPTG epiwafer technology verses a leading Competitor’s epiwafers

• Thickness Uniformity is Comparable• Doping Uniformity is Superior!• Defect Control is Comparable*

*Note: Competitor yield is based on counts of what they refer to as “Killer Defects”. GPTG yield is based on all observable defects on the epiwafer surface. 

GPTG’s Epiwafers Beat the Competition

Summary

• GPTGs epitaxy reactor is in production on 100 mm SiCsubstrates today.

• Doping uniformity, in particular, is better than commercially available epitaxy. 

• Sampling customers on 150 mm substrate epitaxymaterial now and can move to production as soon as the market is ready.

• We can leap ahead of the market using 200 mm SiCsubstrates and above with the right partner.
