High Temperature Oxidation as a Production Route for Electronic Materials () 摘要:Oxidation of metallic components often results in degradation and structural failure, preven-tion is therefore an important topic. On the other hand, oxidation process creates new products such as metal oxides, can be used as a production route. A well-known process in semiconductor industry is that oxidation......
