Gallium nitride substrate

Gallium nitride substrate
Indispensable material for blue-violet lasers

Gallium nitride (GaN) semiconductor is used in blue-violet lasers that enable reading and writing of data from and to next-generation DVD discs. Thus, mass production of GaN substrates becomes a key to enhancing the performance of blue-violet lasers and commercializing this technology. Leveraging its experience in vapor phase synthesis, Sumitomo Electric has established a unique GaN substrate fabrication process and started shipment of the samples.
