Gas annealing
Web7 hours ago · Annealing is currently done in a furnace, requiring temperatures between 1,652 and 2,012 °F (900 to 1,100 °C). The researchers found that using microwave radiation to heat the silicon was almost ... WebAny protective gas mixtures between 100 percent nitrogen and 100 percent hydrogen can be used since every annealing base disposes of its own separate valve stand for the protective gas supply. Consequently, annealing cycles can be implemented with that hydrogen percentage needed to meet process requirements and/or economic aspects.
