Compound Wafer
Compound semiconductors are formed by multy-elements, such as III-V compound, II-VI compound and IV-IV compound.Compared with silicon semiconductors, compound semiconductor is far more expensive and much more difficult to produce large diameter crystal therefore silicon has been major semiconductor materials until nowadays.However,compound semiconductor wafers are being used for applications like LED,LD,solar battery and field-effect transistor and Hall elements based on its light-receiving and emitting,high speed motion and magnetoelectric function.For example,Sapphire,Silicon Carbide (SiC),Gallium Arsenic(GaAs),Gallium Phosphorus(GaP) and Gallium Nitride substrate are being used according to LED application characteristics and thin deposition (epitaxial layer) is formed on substrate in order to produce device function.
About WAFER TECHNOLOGY

III-V Compounds Wafer
Overview
III-V group compound semiconductor formed by group-III and group-V elements. Alumium(Al),Gallium(Ga),Indium(In) are typical group-III elements while Nitrogen(N), Phosphorus(P), Arsenic (As) and Antimony (Sb) are belong to group-V elements.GaN,AlN and InN compound which use group-V element Nitrogen are particularly called as Nitrogen compound.
Key Features and Advantages
Many of III-V compound semiconductors are directly transition semiconductors therefore can be used in emition elements like LED or LD.Further,compound semiconductors have different bandgap compared with Silicon (Si) so they can also be used in light-receiving elements like photo diode.Moreover,they are also widely used in electrical device such as power amplifier or switch,high-speed circit of mobile phone or wireless LAN which is active around our daily lilves.
