Japan is ahead! What are the brands related to “Diamond Semiconductor”? Utilizing “ultimate” performance for practical use in space communication and quantum computer fields
“Diamond semiconductors” expected as next-generation power semiconductorsThe movement towards practical application is attracting attention. Compared to conventional semiconductor materials such as silicon, silicon carbide, gallium nitride, etc., diamond can operate at high temperatures and high voltagesExtremely superior propertiesFrom having”The ultimate semiconductor materialIt is also called”.Energy efficiency and radiation resistanceis also expensive,EV (electric vehicle), quantum computer, aerospace fieldsIt is expected to be used in
The development of diamond semiconductors in Japan is ahead of the world due to industry-academia collaboration.Saga UniversityIs 23/4/23,The world's first electronic circuit incorporating a semiconductor device using diamondsIt was developed. At the end of the same year, a startup from Waseda UniversityPower Diamond Systemssucceeded in passing a large current (6.8 amps) to the diamond semiconductor. Also, startups by Hokkaido University, etc.Okuma Diamond Deviceis developing diamond semiconductors for equipment used in decommissioning nuclear power plants.
High cost and difficulty of processing to make substrates and wafers are issues in practical application, but it seems that technological progress in manufacturing and polishing artificial diamonds used as materials will contribute to the solution.Artificial diamonds are cheaper than natural diamonds where child labor and environmental damage are a problemSo, market expansion is also expected from an ESG perspective. Domestic artificial diamond-related stocks are as follows.
◆ $EDP(7794.JP$
A venture from the National Institute of Advanced Industrial Science and Technology that was listed on the Tokyo Stock Exchange Growth Market in '22.The only manufacturer in Japan of seed crystals, which are the raw materials for artificial diamondsThen, it is sold to overseas artificial gemstone manufacturers, university research institutes, device companies, tool manufacturers, etc. Business performance until the fiscal year ended 23/3 was excellent, but in this fiscal year, exports were suspended from April to June due to the Israeli dispute and Japan's export trade control law revisions.Sales for jewels, which are the main force, have been hit hardI received it. Export permits were obtained from July, and normalized.Rapid growth for devices. The fiscal year ending 2014/3 is expected to be in deficit of 265 million yenStock prices also continue to fall, but the quarterly report predicts a surplus conversion for the fiscal year ending 25/3.On March 22, we released a product suitable for diamond quantum device development.

◆ $Sumiseki Holdings(1514.JP$
Listed on the Tokyo Stock Exchange Standard.Diamond Materials, which is under its umbrella, manufactures and sells artificial polycrystalline diamonds for industrial useI will work on it. The product “SCM Fine Diamond” is used for precision processing of materials that are difficult to process such as ceramics. It also handles these new materials, but the coal business accounts for 90% or more of sales in the holdings as a whole, and dividends from Australian coal mines are a pillar of profit. Consolidated financial results for the fiscal year ending March 24 are expected to decrease sales and increase profit.
