			We asked Bing for a solution with less poisonous chemicals, and she came up with the following recipe [[Eco friendly Polysilicon deposition (CVD)]], however we yet have to verify it in a lab.

	==Hafnium oxide==		==Hafnium oxide==

			There are two ways known so far, which allow for Hafnium oxide deposition, one is using a common CVD the other one is using metalorganic chemical vapour deposition (MOCVD)

			For simplicity and cost reasons I've focused more on the CVD solution so far, because its chemicals required are easier to obtain and the process can be performed with a normal CVD furnace.
