Semiconductor Technologies Laboratory
Focusing on compound semiconductors which are the key materials for photonic devices covering ultraviolet to infrared and superior electronic devices indispensable for wireless and optical communications as well as power electronics, we are conducting research and development on semiconductor materials and their application technologies, as well as peripheral technologies.
Sumitomo Electric’s compound semiconductors and their applications
Compound semiconductors are widely used in various application fields in which silicon devices cannot be used. Sumitomo Electric has developed a variety of materials as a pioneer in this field.
Making use of our technologies of bulk crystal growth, epitaxial growth, simulation technique, characterization and analysis, we are promoting research and development on high-quality, cost-effective solutions for application-specific needs as well as on challenges for new materials.
Product development and key technologies
Compound semiconductors are widely used for optical devices and electronic devices. In each of these areas, we work on the technological development aiming at downstream products such as epitaxial wafers, devices and modules, based on our material and device technologies.
Material design technologies
In the past, material designs depended on experiment alone. However, we are now working on the simulation technologies that will help us expand our total range of R&D, such as the first principle calculation and thermal-fluid analysis technique.
We anticipate various applications, such as the creation of new materials and the development of production process.
Ultracompact RGB laser module
We are developing ultracompact RGB laser modules by the combination of our proven visible laser and precision-packaging technologies and the integration of semiconductor lasers in three primary colors: red, green and blue, optical components and thermoelectric cooler.
We ensure its stable operations for a wide range of temperatures by the integration of three semiconductor lasers composed of different base materials and the effective temperature control using a thermoelectric cooler. We also achieve its high beam quality without bleeding by our laser alignment technology.
It is expected to be applied widely to head-up display, projector, pointer, illumination and other industrial products.
Development of semiconductor thin films
We are conducting research on the thin film growth technology of compound semiconductor crystals. Aiming at the applications to near-infrared sensors for chemical imaging, light-emitting devices and advanced power transistors, novel thin film crystals are being developed using our nano-structural analysis.
