Slight Increase in Exports of Semiconductor Materials from Japan
According to the announcement made by the Japan Society of Newer Metals on their website on December 10th, in the first half of fiscal 2014 (April to September 2014), the shipment value of compound semiconductor materials reached 15.7 billion Japanase yen(approx. USD157 million), 105% up from the previous fiscal year (15 billion yen in the same period in the previous year).
As the readers know very well, a semiconductor is a material that can be an insulator or conductor depending on conditions; therefore, semiconductors are used as materials for many electronic devices, being indispensable to modern technology.
The representative ones are Si, Ge, etc., as single materials, and GaAs, GaP, InP, GeN, CdTe, ZnSe, CdS, GaN, SiC, SiGe, CdZnTe, PbSnTe, HgCdTe, GaAlAs, InGaAs, etc., as compound materials.
GaAs, which counts for the largest market as a compound, is more expensive than Si, features high electron mobility, high-speed operation function, and reduced electric power consumption.
It is used for red LEDs, mobile phones, lasers, etc.
Recently, while exports have kept increasing, the Japanese market has been contracting, and the same tendency continued in the first half of fiscal 2014 (combining domestic sales and exports, the total amount is the same level as the previous year).
The market conditions for the raw material gallium are weak, and we have recently received fewer new inquiries.
Meanwhile, our domestic sales and exports of the other main compound semiconductor raw materials, GaP and InP, have increased.
