Embodiment 1
[0024] A silicon-silicon dioxide substrate is used as the growth substrate, and the thickness of the silicon dioxide layer heat-treated on the silicon surface is 300 nm. The substrate processing process is as follows: first clean the silicon-silica substrate, ultrasonically clean with acetone, ethanol and deionized water for 10 minutes, and then use a mixed solution of sulfuric acid and hydrogen peroxide with a volume ratio of 3:1 in 160 Clean at ℃ for 30 minutes, and then ultrasonically clean with deionized water for 5 minutes to remove excess concentrated sulfuric acid on the surface; put the cleaned silicon-silica substrate into 40-44wt% ammonia sulfide solution for 24 hours and soak The resulting silicon-silica substrate was finally ultrasonically cleaned in deionized water for 2 minutes, and the substrate was blown dry with high-purity nitrogen; the dried silicon-silica substrate was stored in vacuum for 24 hours to remove residual organic matter. Anneal the above substrat...
Embodiment 2
[0029] With aluminum oxide (Al 2 O 3 ) The substrate is a growth substrate, and the film deposition surface is the (100) surface of aluminum oxide. The substrate processing process is as follows: firstly, the aluminum oxide substrate is cleaned, ultrasonically cleaned with acetone, ethanol and deionized water for 10 minutes, and then a mixed solution of sulfuric acid and hydrogen peroxide in a volume ratio of 3:1 is used at 160℃ After cleaning for 30 minutes, and then ultrasonic cleaning with deionized water for 5 minutes to remove the excess concentrated sulfuric acid on the surface; put the cleaned aluminum oxide substrate into 40-44wt% ammonia sulfide solution for 24 hours, and the Finally, the aluminum oxide substrate was ultrasonically cleaned in deionized water for 2 minutes, and the substrate was blown dry with high-purity nitrogen; the blown-dried aluminum oxide substrate was stored in vacuum for 24 hours to remove residual organic matter. . Anneal the above substrate ...
