Monocrystalline diamond wafer is on the market with a most working temperature at 600℃ from PAM-XIAMEN. https://www.powerwaywafer.com/
The way to make single crystal diamond substrate wafers? Here’s a quick video for introducing the diamond wafer manufacturing course of briefly. Firstly, lower the small movie from a diamond with laser. Then, spray the resin and chemical brokers on the diamond movie and put it on a curler with diamond particles to shine. After that, cowl them with a metallic field, and fill in hydrogen and methane fuel. Improve the stress contained in the machine, and warmth the diamond movie to over 1000℃ in order that the methane will decompose carbon atoms, which type plasma on the diamond movies to assist them develop. That is the entire progress strategy of the diamond wafers.
