Research & Innovation


Semiconductor Wafer Inc. ( SWI ) provides high purity single crystal ZnO wafer and ZnO bulk for power device , LED , sensor and detector applications . With an ideal crystal structure , ZnO wafer ( Zinc oxide ) has a 2% lattice mismatch to GaN , that is much less than the lattice mismatch of sapphire wafer and SiC wafer . ZnO wafer is one of the most suitable substrate for using as GaN epitaxial growth and wide band gap semiconductor application . ZnO wafer are supplied in square shape , undoped , size 10 x 10 x 0.5 mm , double sides polished surface finish and <0001> oriented , our high quality ZnO wafer have been widely used for the growth of nitride base devices . Please contact us for more product information .
