Mainly used for preparation of compound semiconductor, electronic components, refrigeration, thermoelectric conversion element and the atomic reactor in the liquid cooling carrier.
We supply SiC substrates(substrates made from semiconductor compounds), which we developed using our independently developed film deposition technology, both domestically and abroad.
Hitachi Cable manufactures supplies aluminum gallium arsenide(AlGaAs) epitaxial wafers and aluminum gallium indium phosphorus(AlGaInP) epitaxial wafers, both of which are compound semiconductor wafers for red LEDs.
SiC is a compound semiconductor that is extremely stable--thermally, chemically, and mechanically stable; the parameters that are important for use in power devices are excellent.
Context of the acquisition AKM is accelerating the development of business utilizing invisible optics(ex. IR and UV) based on its core technology for compound semiconductors.
With regard to compound semiconductor materials, the division supplies high-output LEDs including ultraviolet and infrared ray lights for use in vegetable plant growing facilities, displays, sensors and other industrial products.
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.
Mitsubishi Chemical's Epitaxial Wafers for Light Emitting Diode are high-quality, high-value-added compound semiconductor substrates. The LED layered structures are epitaxially grown on a Gallium Arsenide or Gallium Phosphide substrate by HVPE( Hydride Vapor Phase Epitaxy) or LPE( Liquid Phase Epitaxy).
Furthermore, as well as wire and cable, optical device products, optical fiber gyro for use in car navigation systems, compound semi-conductor wafers, wire and cable accessories and assemblies are also included in the certification.
The key product in this area is lapping plates made from a specially formulated ductile cast iron that are designed to produce thinner and smoother silicon wafers, glass substrates, sapphire substrates, compound semiconductors, and other products at even higher levels of precision.
This new LED also uses the ultraviolet LED epitaxial wafer technology developed as part of the high-efficiency electro-optic conversion compound semiconductor development program(the Light for the 21st Century project) of the New Energy and Industrial Technology Development Organization NEDO.
We have invested in the compound semi-conductor manufacturer-Giga Epitaxy Technology Corp.(hereunder written as GET) in the Taiwan region, and by mutual consent, have signed an agreement, to provide manufacturing technology related to our Gallium Arsenide compound semi-conductor epitaxial wafer.
In technical college, Noguchi and his teammates participated in a robot contest with their handcrafted motor driver, and in college, he researched compound semiconductors, LED, and LSI, diligently applying himself to the fields that are necessary to become a design engineer.
This period also saw progress in the R&D of high-speed devices exceeding the performance limits of Si devices. These included Josephson devices using superconductivity and compound semiconductor devices such as GaAs having higher electron mobility than Si devices.
IT-related Chemicals Sector| SUMITOMO CHEMICAL Optically functional films, touch screen sensor panels and color resists that are used to make LC and OLED displays; photoresists and high-purity chemicals required in the semiconductor manufacturing process; compound semiconductor materials used in antenna switches and other components of communication terminal equipment.
Next to oxygen, silicon is the most abundant element in the earth's crust, and is always found in sand and stone in nature. Germanium, silicon, and compound semiconductor elements are generally refined from raw ore.
In the latter half of 1960s, he began research on electrooptic effect of compound semiconductors and its application to bulk type optical modulators. Since early 1970s when integrated optics started, he has been working mainly on guided-wave-optic and integrated modulators/switches and related materials.
In recent years, in the midst of the explosive proliferation of wireless communication using mobile phones and mobile personal computers etc., the demand for compound semi-conductor material, especially Gallium Arsenide-used in these receiving/transmitting devices-has been rapidly increasing.
The new plant will play a key role as a base for production of high-performance Hall elements for use in cell phones, consumer electronics, automotive, and an expanding range of growing application fields, and will serve as the core for new business development in the field of compound semiconductor thin film devices.
