CVD VS PVD

Chemical vacuum deposition- CVD:

CVD (Chemical Vacuum Deposition) refers to the process of introducing vapors of gaseous or liquid reactants containing film elements into the reaction chamber and reacting with other gases to form thin films on the substrate surface. At present, metal-organic compounds are mainly used as precursors to deposit films on substrates by chemical reaction.

Stanford Advanced Materials can be used for high purity organometallic compounds. These products strictly control the content of metal impurities and are the preferred materials for MOCVD. They are widely used in LED, aerospace, display, electronics, new energy batteries, solar cells and other fields.

Physical vapor deposition -PVD:

PVD, physical vapor deposition, refers to the vaporization of materials into atoms, molecules or ionization into ions under vacuum conditions, and through the vapor process on the substrate to deposit a layer of film with special properties. There is no chemical change in the process. According to the different ion sources, PVD has the following ways: thermal evaporation, sputtering, ion plating.

Stanford Advanced Materials provides a variety of high purity elements, compounds, ceramics and other coating materials. Widely used in LED, aerospace, display, electronics, new energy batteries, solar cells and other fields.

Sputter coating is a kind of PVD. The company can provide target for pure metal, alloy and ceramics. Metal and alloy targets are prepared by casting and powder metallurgy. Ceramic targets are mainly prepared by hot pressing. In order to match different sputtering instruments, target shapes are different, mainly round target, square target, irregular shape target, hollow target, solid target and so on, which are generally customized according to requirements.

Target materials are widely used in IC, information storage, flat panel display, optical film, new energy battery, solar cell, superhard material coating, decorative coating and other fields.
